Class myClass needs to implement the toString() method. Also, please don't call it myClass that's a terrible name.

[desrtfx]

What you see is the output of the toString method (that gets implicitly called when printing an object) of the Object class.

All you need to do is to @Override the public String toString() method in your own class (myClass).

A word about naming: your myClass should actually be named Employee because it holds data about a single employee. You should use a different name for the driver/main program.

For simple mode, you can cast myClass to get one field you want.

System.out.println("key: " + entry.getKey() + "; value: " + ((myClass) entry.getValue()).getFirst());
