Java: String.toLowerCase() strange boolean result

[Lycanus Darkbinder]

Note: I didn't post this in Modder support because it isn't a Java "school" as the description says.

 

At any rate, I was trying to set a boolean flag based on the dimension name but found that in this particular code snippet isNether always equals false.

 

// Assuming dimID is -1
String dimName = DimensionManager.getProvider(dimID).getDimensionName().toLowerCase();
boolean isNether = (dimName == "nether");

 

If I hover over dimName in Eclipse it says nether and the byte array associated with it is 6 characters so there doesn't appear to be any newline character at the end.

 

Note: I am using equalsIgnoreCase("nether") but I'm curious why toLowerCase() doesn't work.

toLowerCase works, you just can't compare Strings with == because that checks for identity on objects, not equality.

 

Ah, thanks. I guess I need a Java refresher, been in the C++ universe too long.
