Java While Loop

Unlike for-loop , the while loop is used when the number of iterations is unknown. The while loop will execute a 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, 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
