Did you have a question?

[bairava surya]

this program doesnt compile?

Are you asking if the program compiles? ,,,

Isn't it easier to just try to compile it?

And if it doesn't compile, and you're asking why, maybe you should tell us what the error message is?

[bairava surya]

it is showing error as illegal character \160

[Campbell Ritchie]

That suggests you have been using a word processor rather than a text editor. Find out what \160 is: look in the Unicode website for it; I think it is \u0070. But that comes out as p so it must be 160 in decimal not octal so try \u00a0 instead and see what that is.

By the way, your choice of names for your types and variables is really bad. This1?

Please indent your code consistently and put one blank like before each method or constructor. It is difficult to read as it is.

Hi Bairava,
Let me try to explain ..

In main() you are creating one object of type This1 by using new This1() .When the object is being created it is calling the no-arg constructor , now here is the trick .In the constructor

This1() {
		System.out.println(this);
	}

System.out.println(this) means it is calling the This1 object and internally calling the overridding toString() .
We are getting the expected output as :TestClasssi10

Hope you understand .

Thanks ,
Satya
