Java for Loop Program

This Java program demonstrates the usage of for loop statement in Java:

public class ForTest {
  public static void main(String args[]) {
    int x;
  
    for(x = 0; x<10; x = x+1)
      System.out.println("This is x: " + x);
  }
}

Output:

This is x: 0
This is x: 1
This is x: 2
This is x: 3
This is x: 4
This is x: 5
This is x: 6
This is x: 7
This is x: 8
This is x: 9

The for loop with block statements:

/*
  Demonstrate a block of code.
  
  Call this file "BlockTest.java"
*/
public class BlockTest {
  public static void main(String args[]) {
    int x, y;
  
    y = 20;

    // the target of this loop is a block
    for(x = 0; x<10; x++) {
      System.out.println("This is x: " + x);
      System.out.println("This is y: " + y);
      y = y - 2;
    }
  }
}

Output:

This is x: 0
This is y: 20
This is x: 1
This is y: 18
This is x: 2
This is y: 16
This is x: 3
This is y: 14
This is x: 4
This is y: 12
This is x: 5
This is y: 10
This is x: 6
This is y: 8
This is x: 7
This is y: 6
This is x: 8
This is y: 4
This is x: 9
This is y: 2
