Java While Loop

    Unlike for-loop, while loop is used when the number of iteration is not known. The while loop will execute the program several times until the condition is false. Syntax

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

    Example

    public class WhileExample {  
    public static void main(String[] args) {  
        int i=1;  
        while(i<=3){  
            System.out.println(i);  
        i++;  
        }  
    }  
    }

    Output

    1
    2
    3

    Infinitive while loop

    The while loop will execute infinite time when we pass the true value as the condition. If you want to exit from the infinite loop then press ctrl+c. 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 
    infinitive while loop 
    infinitive while loop 
    infinitive while loop 
    infinitive while loop 
    ctrl+c
