Java comparison with == of two strings is false?

Question

This question already has answers here:

Answer 1

The == operator compares the object references, not the value of the Strings.

To compare the values of Strings, use the String.equals method:

"231".equals(parts[0]);

This is true with any other object in Java -- when comparing values, always use the equals method rather than using the == operator.

The equals method is part of Object, and should be overridden by classes which will be compared in one way or another.
