System.out.println() question

[Chetan Dorle]

Hi All,

One of the interviewer asked the below question

In main method we have out.println("world") stmt . After executing this we want output as Hello world . How will you write code without calling any method of other class or not passing runtime input from args[].

Can you guys please give your input.

Thanks in advance....

after returning main? if yes:look for threads else include one more out.print ;)

Hi Seetharaman ,

Thanks for the reply . Yes it is in the main() so will return output in the excution .

Can you please give some input on how to do it with threads.

Thanks ..

It says after executing this. Did you ask exactly what they mean by that? Simply leaping in with a solution is far less likely to get you appointed than asking lots of questions.

public class InterviewQ{
  static{
     System.out.print("Hello ");
  }
  public static void main(String[] args){
     System.out.print("world");
   }
}

That should work, yes.

just another idea. Here you can modify the initial output however you like:

public class Output {

	public static Output out;
	
	public static void printf(String input) {
		System.out.printf("Hello World");
	}
	
	static {
		out = new Output();
	}
	
	public static void main(String[] args) {
		out.printf("World");
	}
}

Cheers,
Michael
