How to program calculator in java


Hello,
If the question is : how to make a programmable calculator run a program written in Java, the amswer is : you cannot. Maybe the newer ones.

But if you are looking for the source code of a Java applet that simulates a calculator, then maybe you should launch a Google search with keywords Java calculator and see what you get. I do not want to spoil your fun by supplying a link to what my search returned.
Hope it helps.

What is the difference between Java editor and Java software?


java editor is a text editor which probably understands java language synthax and can automatically call java to compile your code.
Java software is a program written in Java programming language which is interpreted/executed by JVM(JAva virtual machine) on a target computer.
Your question is a rough equivalent to : What is a difference between typewriter and a recipe book written in English language
