I have a method (par.getstatus) which outputs a message that looks exactly like this: 3::0::P:3::C:2::S:1::M:1::D:0::A:0::Q:0null

problem is when I write:

    String s = par.getStatus(3);
    assertTrue(s == "3::0::P:3::C:2::S:1::M:1::D:0::A:0::Q:0null");

it does not return true. I know that the string is the right one, cause I printed it to the console, and copied and pasted it directly, checked that I did that right many times. And to check that it is not the assertTrue method that I am using that is wrong, I wrote:

    String d = "rr";
            assertTrue(s == "rr");

which returns true.

Someone said that it could be null that is causing the problems, so i removed that, but still no luck. Does anyone know what the problem could be here? thanks

    Please search for answers on SO... You should never compare strings (or, indeed, most objects) in java using the == comparison operator. Use `aString.compareTo(otherString)` or `aString.equals(otherString)`. – jgitter May 12 '14 at 12:44
  • thanks I did search but missed the other thread, will look harder next time. thanks for your help. – user1319364 May 12 '14 at 12:51

s == "3::0::P:3::C:2::S:1::M:1::D:0::A:0::Q:0null"

== compares the references of two Strings and these two strings are not the same Object.

use String.equals() to compare the content of two Strings: Have look at this question.

assertTrue(s.equals("3::0::P:3::C:2::S:1::M:1::D:0::A:0::Q:0null"));
