String Problem

[Vijay Kumar]

Hi..all
I am compiling and executing a simple String program on JDK 1.5
my code is....

   
public class StringTest {
public static void main(String[] args){
String str1="HELLO";
String str2="HELLO";
System.out.println("str1.equals(str2):"+str1.equals(str2));
System.out.println("str1==str2       :"+str1==str2);
}
}

its out put is :
str1.equals(str2):true
false

but I am expecting

str1.equals(str2):true
str1==str2 :false

why does str1==str2 : is disappeared in outout


help me out please.

Thanks

The reason is that + has higher precedence than ==, so the String concatenation is performed first, and then the resulting String is compared with == to str2.

Also I would expect that when you fix the String concatenation problem, you won't get a false in the second statement.
