public class Test {
	public static void main(String[] args) {
		 
		 //  String str="c:\program\user"; Error Invalid unicode 
		String str1="c:\\Program\\user";
		
	}

}

Q1. If I have commented then also why it is giving error.If have commneted then it is supposed not to read by compiler So their is no question What I have written?
Q1.If I have enclosed within double quote("") It should consider as String?

I get no compiler error when I try your code.

What is the exact text of the error you are getting?

I even tried it from the cmd prompt and got below error.

Test.java:7: illegal unicode escape
// String str="c:\program\user"; Error Invalid unicode "
^
1 error

yeah correct but after commenting also it is giving error why ?

My mistake...i was not compiling what i thought i was.

my guess is that this is due to the unicode conversion that happens before much else. Even though it is a comment, something is trying to make it unicode, so the "\u" is being read as a unicode reference.

If you change the comment line to something like

// String str="c:\program\puser"; Error Invalid unicode

it compiles.
