Write a code in java to explain the while loop in Java?

// This is the Hello program in Java

class Hello {

public static void main (String args[]) {

System.out.print("Hello "); // Say Hello
int i = 0; // Declare and initialize loop counter
while (i < args.length) { // Test and Loop
System.out.print(args[i]);
System.out.print(" ");
i = i + 1; // Increment Loop Counter
}
System.out.println(); // Finish the line
}

}
