hi i have this method

 public class Validate {
	String name;
	public boolean val( String strName)
	{
		name=strName;
		boolean b=true;
		if(name.length()<3)
		b=false;
		return b;
	}
}   

so how can i determine that this method returns true in if condition?

Can you elaborate what you are trying to accomplish?

There could be a lot of catches in what you are asking & we can lead you to the solution(not provide it).

Please use the code tag if you are trying to paste the code.

[Raymond Tong]

so, you want to call a method inside if statement ?

 if (myMethod())

Well, the easiest way is to call the method and see what it returns. Any reason you can't do that?

[Avishkar Nikale]

I suggest you start by reading a good book on Java to get hold on
language constructs.

This is very trivial & once you go through a good book you can write this code.

For your information the if condition accepts any boolean value or
call to a boolean function inside the round-brackets.

Hope this will lead you to the solution.

ya i want to call method inside the if() and check where it is true...

Just call that method by passing some argument, you'll get to know what this method returns.

boolean isValidName = val("Hello");

Is this what you want? I'm not sure of my interpretation though..

[David Newton]

Just for clarity, you're not checking the return type of the method, you're checking the returned *value*. They mean quite different things.

Have a look at the code conventions; there is something very similar to what you want in §10.5.2.
