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:


while(condition){  
//code to be executed  
}

Example:

public class WhileExample {  
public static void main(String[] args) {  
    int i=1;  
    while(i<=10){  
        System.out.println(i);  
    i++;  
    }  
}  

Output:

3
4
5
6

Java Infinitive While Loop

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


Syntax:


while(true){  
//code to be executed  
  

Example:

public class WhileExample2 {  
public static void main(String[] args) {  
    while(true){  
        System.out.println("infinitive while loop");  
    }  
}  

Output:
infinitive while loop

ctrl+c

Now, you need to press ctrl+c to exit from the program.
