System.out.Println with operator ==

[Shiva Kumar Shedad]

class TestOut
{
public static void main(String[] args)
{
String s1 = "shiva";
String s2 = s1;
System.out.println("Hello World! :: "+ s1==s2);
System.out.println("Hello World! :: "+ s1.equals(s2));
}
}

I'm not sure why the "Hello WOrld! :: " of first SOP does not print on console when i run this program?

[nans nav]

in case of first SOP i.e
System.out.println("Hello World! :: "+ s1==s2);
comparing is made like this :
(("Hello World! :: "+ s1) == s2 which will return you false.
If you keep the s1==s2 in braces you will get the desired result:
System.out.println("Hello World! :: "+ (s1==s2));

output:
Hello World! :: true
