How to run Java Programs

Question

I am just starting Java but I know Scheme...How do you run java code using emacs and putty? I made a program and saved it as first.java on emacs and when i try to open it in putty i did load "first.java" but nothing happened so how do you do this and can yo write Java code in Dr.Scheme?

Answer 1

First, you have to name your file the same as the public class that is contained in the file. Then, once your class is written, you need to compile it using javac and run the .class file that is produced using the command java [ClassName].

A few things to note is that you are going to make sure you have a Java Development Kit (JDK) and that your path is set up so that javac and java are on the path.

I would poke around the Java Tutorials, specifically the "Hello World" application example.
