The output of the program in Method Overloading in Java:

/opt/tools/java/jdk1.8.0_60/bin/java com.mrbear.App

So, from the tutorials¹:

Note: Overloaded methods should be used sparingly, as they can make code much less readable.

Quoting² from the JLS³:

When a method is invoked (§15.12), the name of the class, the name of the method, the number of actual arguments and the compile-time types of the arguments are used, at compile time, to determine the signature of the method that will be invoked (§15.12.2).
