In this part, you will figure out how to utilize SQLite in Java programs. 

Installation

Before you begin utilizing SQLite in our Java programs, you need to ensure that you have SQLite JDBC Driver and Java set up on the machine. You can check Java instructional exercise for Java establishment on your machine. Presently, let us check how to set up SQLite JDBC driver. 

• Download most recent adaptation of sqlite-jdbc-(VERSION).jar from sqlite-jdbc storehouse. 
• Add downloaded container record sqlite-jdbc-(VERSION).jar in your group way, or you can utilize it alongside - classpath alternative as clarified in the accompanying models. 

Following area expects you have little information about Java JDBC ideas. On the off chance that you don't, at that point it is proposed to went through thirty minutes with JDBC Tutorial to get settled with the ideas clarified underneath. 

Connect to Database

Following Java programs tells the best way to associate with a current data set. On the off chance that the information base doesn't exist, at that point it will be made lastly a data set item will be returned. 

import java.sql.*;

public class SQLiteJDBC {
  public static void main( String args[] ) {
      Connection c = null;
      
      try {
         Class.forName("org.sqlite.JDBC");
         c = DriverManager.getConnection("jdbc:sqlite:test.db");
      } catch ( Exception e ) {
         System.err.println( e.getClass().getName() + ": " + e.getMessage() );
         System.exit(0);
      }
      System.out.println("Opened database successfully");
   }
}

Presently, we should accumulate and run the above program to make our data set test.db in the current registry. You can change your way according to your necessity. We are accepting the momentum adaptation of JDBC driver sqlite-jdbc-3.7.2.jar is accessible in the ebb and flow way. 

$javac SQLiteJDBC.java
$java -classpath ".:sqlite-jdbc-3.7.2.jar" SQLiteJDBC
Open database successfully

In the event that you will utilize Windows machine, at that point you can arrange and run your code as follows − 

$javac SQLiteJDBC.java
$java -classpath ".;sqlite-jdbc-3.7.2.jar" SQLiteJDBC
Opened database successfully

Create a Table

Following Java program will be utilized to make a table in the recently made data set. 

import java.sql.*;

public class SQLiteJDBC {

   public static void main( String args[] ) {
      Connection c = null;
      Statement stmt = null;
      
      try {
         Class.forName("org.sqlite.JDBC");
         c = DriverManager.getConnection("jdbc:sqlite:test.db");
         System.out.println("Opened database successfully");

         stmt = c.createStatement();
         String sql = "CREATE TABLE COMPANY " +
                        "(ID INT PRIMARY KEY     NOT NULL," +
                        " NAME           TEXT    NOT NULL, " + 
                        " AGE            INT     NOT NULL, " + 
                        " ADDRESS        CHAR(50), " + 
                        " SALARY         REAL)"; 
         stmt.executeUpdate(sql);
         stmt.close();
         c.close();
      } catch ( Exception e ) {
         System.err.println( e.getClass().getName() + ": " + e.getMessage() );
         System.exit(0);
      }
      System.out.println("Table created successfully");
   }
}

At the point when the above program is accumulated and executed, it will make COMPANY table in your test.db and last posting of the document will be as per the following − 

-rw-r--r--. 1 root root 3201128 Jan 22 19:04 sqlite-jdbc-3.7.2.jar
-rw-r--r--. 1 root root    1506 May  8 05:43 SQLiteJDBC.class
-rw-r--r--. 1 root root     832 May  8 05:42 SQLiteJDBC.java
-rw-r--r--. 1 root root    3072 May  8 05:43 test.db

INSERT Operation

Following Java program tells the best way to make records in the COMPANY table made in above model. 

import java.sql.*;

public class SQLiteJDBC {

   public static void main( String args[] ) {
      Connection c = null;
      Statement stmt = null;
      
      try {
         Class.forName("org.sqlite.JDBC");
         c = DriverManager.getConnection("jdbc:sqlite:test.db");
         c.setAutoCommit(false);
         System.out.println("Opened database successfully");

         stmt = c.createStatement();
         String sql = "INSERT INTO COMPANY (ID,NAME,AGE,ADDRESS,SALARY) " +
                        "VALUES (1, 'Paul', 32, 'California', 20000.00 );"; 
         stmt.executeUpdate(sql);

         sql = "INSERT INTO COMPANY (ID,NAME,AGE,ADDRESS,SALARY) " +
                  "VALUES (2, 'Allen', 25, 'Texas', 15000.00 );"; 
         stmt.executeUpdate(sql);

         sql = "INSERT INTO COMPANY (ID,NAME,AGE,ADDRESS,SALARY) " +
                  "VALUES (3, 'Teddy', 23, 'Norway', 20000.00 );"; 
         stmt.executeUpdate(sql);

         sql = "INSERT INTO COMPANY (ID,NAME,AGE,ADDRESS,SALARY) " +
                  "VALUES (4, 'Mark', 25, 'Rich-Mond ', 65000.00 );"; 
         stmt.executeUpdate(sql);

         stmt.close();
         c.commit();
         c.close();
      } catch ( Exception e ) {
         System.err.println( e.getClass().getName() + ": " + e.getMessage() );
         System.exit(0);
      }
      System.out.println("Records created successfully");
   }
}

When above program is assembled and executed, it will make given records in COMPANY table and will show following two line − 

Opened database successfully
Records created successfully

SELECT Operation

Following Java program tells the best way to get and show records from the COMPANY table made in the above model. 

import java.sql.*;

public class SQLiteJDBC {

  public static void main( String args[] ) {

   Connection c = null;
   Statement stmt = null;
   try {
      Class.forName("org.sqlite.JDBC");
      c = DriverManager.getConnection("jdbc:sqlite:test.db");
      c.setAutoCommit(false);
      System.out.println("Opened database successfully");

      stmt = c.createStatement();
      ResultSet rs = stmt.executeQuery( "SELECT * FROM COMPANY;" );
      
      while ( rs.next() ) {
         int id = rs.getInt("id");
         String  name = rs.getString("name");
         int age  = rs.getInt("age");
         String  address = rs.getString("address");
         float salary = rs.getFloat("salary");
         
         System.out.println( "ID = " + id );
         System.out.println( "NAME = " + name );
         System.out.println( "AGE = " + age );
         System.out.println( "ADDRESS = " + address );
         System.out.println( "SALARY = " + salary );
         System.out.println();
      }
      rs.close();
      stmt.close();
      c.close();
   } catch ( Exception e ) {
      System.err.println( e.getClass().getName() + ": " + e.getMessage() );
      System.exit(0);
   }
   System.out.println("Operation done successfully");
  }
}

At the point when the above program is arranged and executed, it will deliver the accompanying outcome.

UPDATE Operation 

Following Java code tells the best way to utilize UPDATE explanation to refresh any record and afterward bring and show the refreshed records from the COMPANY table. 

import java.sql.*;

public class SQLiteJDBC {

  public static void main( String args[] ) {
  
   Connection c = null;
   Statement stmt = null;
   
   try {
      Class.forName("org.sqlite.JDBC");
      c = DriverManager.getConnection("jdbc:sqlite:test.db");
      c.setAutoCommit(false);
      System.out.println("Opened database successfully");

      stmt = c.createStatement();
      String sql = "UPDATE COMPANY set SALARY = 25000.00 where ID=1;";
      stmt.executeUpdate(sql);
      c.commit();

      ResultSet rs = stmt.executeQuery( "SELECT * FROM COMPANY;" );
      
      while ( rs.next() ) {
         int id = rs.getInt("id");
         String  name = rs.getString("name");
         int age  = rs.getInt("age");
         String  address = rs.getString("address");
         float salary = rs.getFloat("salary");
         
         System.out.println( "ID = " + id );
         System.out.println( "NAME = " + name );
         System.out.println( "AGE = " + age );
         System.out.println( "ADDRESS = " + address );
         System.out.println( "SALARY = " + salary );
         System.out.println();
      }
      rs.close();
      stmt.close();
      c.close();
   } catch ( Exception e ) {
      System.err.println( e.getClass().getName() + ": " + e.getMessage() );
      System.exit(0);
   }
    System.out.println("Operation done successfully");
   }
}

At the point when the above program is accumulated and executed, it will create the accompanying outcome.

SALARY = 20000.0

ID = 4
NAME = Mark
AGE = 25
ADDRESS = Rich-Mond
SALARY = 65000.0

Operation done successfully

DELETE Operation

Following Java code tells the best way to utilize use DELETE proclamation to erase any record and afterward bring and show the leftover records from the our COMPANY table. 

import java.sql.*;

public class SQLiteJDBC {

   public static void main( String args[] ) {
      Connection c = null;
      Statement stmt = null;
      
      try {
         Class.forName("org.sqlite.JDBC");
         c = DriverManager.getConnection("jdbc:sqlite:test.db");
         c.setAutoCommit(false);
         System.out.println("Opened database successfully");

         stmt = c.createStatement();
         String sql = "DELETE from COMPANY where ID=2;";
         stmt.executeUpdate(sql);
         c.commit();

         ResultSet rs = stmt.executeQuery( "SELECT * FROM COMPANY;" );
         
         while ( rs.next() ) {
         int id = rs.getInt("id");
         String  name = rs.getString("name");
         int age  = rs.getInt("age");
         String  address = rs.getString("address");
         float salary = rs.getFloat("salary");
         
         System.out.println( "ID = " + id );
         System.out.println( "NAME = " + name );
         System.out.println( "AGE = " + age );
         System.out.println( "ADDRESS = " + address );
         System.out.println( "SALARY = " + salary );
         System.out.println();
      }
      rs.close();
      stmt.close();
      c.close();
      } catch ( Exception e ) {
         System.err.println( e.getClass().getName() + ": " + e.getMessage() );
         System.exit(0);
      }
      System.out.println("Operation done successfully");
   }
}

When the above program is compiled and executed, it will produce the following result.

Opened database successfully
ID = 1
NAME = Paul
AGE = 32
ADDRESS = California
SALARY = 25000.0

ID = 3
NAME = Teddy
AGE = 23
ADDRESS = Norway
SALARY = 20000.0

ID = 4
