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
