1. copy the work without changing it
2. modify the work providing you send me a copy which I can use in any way I want, including incorporating into this work.

6. fold the work into a funny hat and wear it on your head.

This is not thread safe, not high performance, and doesn't tell EOF. It's intended for low-volume easy keyboard input. An example of use is:

EasyIn easy = new EasyIn();
int i = easy.readInt(); // reads an int from System.in
float f = easy.readFloat(); // reads a float from System.in
