Java While Loop

The Java while loop is used to iterate a part of the program several times. If the number of iteration is not fixed, it is recommended to use while loop.

Syntax:

1. while(condition){  
2. //code to be executed  
3. }  

Example:

1. public class WhileExample {  
2. public static void main(String[] args) {  
3.     int i=1;  
4.     while(i<=10){  
5.         System.out.println(i);  
6.     i++;  
7.     }  
8. }  
9. }  

Output:

1
2
3
4
5
6
7
8
9
10

Java Infinitive While Loop

If you pass true in the while loop, it will be infinitive while loop.

Syntax:

1. while(true){  
2. //code to be executed  
3. }  

Example:

1. public class WhileExample2 {  
2. public static void main(String[] args) {  
3.     while(true){  
4.         System.out.println("infinitive while loop");  
5.     }  
6. }  
7. }  

Output:

infinitive while loop
infinitive while loop
infinitive while loop
infinitive while loop

ctrl+c
