While Loop

Lesson 9 of 11 in Coddy's Control Statements in Java course.

The while loop is used to iterate a part of the program repeatedly until the specified condition is true; if the condition is false, the loop automatically stops.

While loop is a kind of countdown like you do on New Year's Eve from ten to one.

Syntax:

while (condition){    
	// code to be executed   
	// Increment / decrement statement  
}

Challenge

Easy

Write a simple program to print "Hello World! " 5 times using the while loop. Make sure you have space after the exclamation mark and do not print on a new line.

Try it yourself

class Hello {
    public static void hello() {
        // Write code here
    }
}
