Loops in Java

Loops In Java

In Java, there may be requirement of the situation that you wants to execute a piece of code number of times, In that case loops may help you to handle the situation and run code multiple times.


Types of loop in java:-

  1. do...while loopLike a while statement, except that it tests the condition at the end of the loop body.

2. while loopRepeats a statement or group of statements while a given condition is true. It tests the condition before executing the loop body. 


3. for loopExecute a sequence of statements multiple times and abbreviates the code that manages the loop variable.

  

Example do..while Loop:


public class Loops {


public static void main(String[] args) {

do {
System.out.println(a);
a++;
}while(a<10);

}

}


Example while Loop:



public class Loops {

public static void main(String[] args) {

int a = 10;
while(a>0) {
System.out.println(a);
a--;
}

}

}

Example for Loop:

public class Loops {

public static void main(String[] args) {

for(int a=10; a>0; a--) {
System.out.println(a);
}

}

}
