Is it possible to properly compare objects using the operators >, < and == in Java? I have implemented the Comparable interface in one of my objects.

It would save some time and be nice to write

if (obj1 < obj2) do sth

instead of

if (obj1.compareTo(obj2) < 0) do sth

Is that possible if I implement something else or does it generally not work like this?

  • No Java does not support operator overloading (except for Strings that you can concatenate with +). Commented Dec 10, 2014 at 11:21

No, this is not possible. Java does not support operator overloading.

You might want to check Groovy, which is a Java like language that runs on the JVM and does support operator overloading.

@CGFoX You can also check Scala which runs on the JVM and support operator overloading (you could even mix Scala and Java code).

In a word- no, it is not possible. Java does not support operator overloading, and the comparison operators (<, <=, > and <=) are reserved for primitive types only.

No, it's not possible. These operators only work on primitive types.

< > Operators are only usable on primitives - such as integers.
