Java While Loop
As we are discussed in previous file, java while loop is used to repeat the part of the program many times. If the number of repetition is not fixed, then while loop is use.
Syntax
while (condition)
{
statements (s)
}
Flowchart
In above flowchart shows, firstly, condition is evaluated and if condition is true then statement in while loop is executed. If condition is false,then it comes to out of the loop and go to next statement.
Example
public class whileLoopExample{
public static void main(String[]args){
int i=1;
while(i<=15){
System.out.println(i);
i++;
}
}
}
Output

Infinitive While Loop
In while loop if we pass true it will be infinitive while loop.
Syntax
while (true){
statement(s);
}
Example
class WhileInfinitiveExample2 {
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
Ctrl+c is use to exit the program
