Java Basics Using Qt Jambi Tutorial

2. Looping Statements

   3. while, do-while statements – The while statement executes a block while the condition is true.

Ex.

import java.lang.*;

public class MovingCar{

static boolean ismoving = true;

static boolean breaks = false;

public static void main(String[] args){

while(ismoving){

if(breaks){

ismoving = false;

System.out.println("breaks is applied...stopped.");

}

else{

System.out.println("The car is moving.");

}

breaks = true;

}

}

}

This code prints “The car is moving.” once and breaks is applied and goes out of the while loop.

Do-while statements' difference is hat the condition is placed at the bottom and executes the block of code once.

Ex.

do{

//statements

}while (condition);

4. For Loop

Ex. for (x=0; x<10;>

//increment or decrement (x--)using unary operator

//initialization and executes once.

//Condition when met, or when it evaluates to false, it terminates.

System.out.println(x);

}
