While Loop in Java

While Loop in Java

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:

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:

 

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

ctrl+c

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