So I want to write java programs on Windows, besides writing codes, I have to be able to compile and test the programs, there are a few steps that need to be done before I could really do it without errors.<\/em><\/p>\n

I needed Java SE Development Kit JDK 8<\/a>, download and install. I use notepadd++<\/a> to write codes.<\/em><\/p>\n

Now, Windows doesn’t know where javac or path of the program are, I have to set them or I’ll get all the errors. Using cmd windows and set the path. At the prompt:<\/em><\/p>\n

\n

set path=”C:\\Program Files\\Java\\jdk1.8.0_20\\bin”<\/em><\/p>\n

set classpath=%classpath%;.; \/\/don’t forget the little “.” between ;;<\/em><\/p>\n<\/blockquote>\n

\"java<\/a>\u00a0 \u00a0 \u00a0\"javatxt\"<\/a><\/p>\n

So, I used notepad++ to create a program call HelloWorld.java in my portable drive J:\\java\\programs\\ with the content:<\/em><\/p>\n

\n

public class HelloWorld {
\npublic static void main(String[] args) {
\nSystem.out.println(“Hello World.”);
\n}
\n}<\/p>\n<\/blockquote>\n

Now I can compile the program with “javac HelloWorld.java”<\/em><\/p>\n

Below is the screen shot of all the problems before I set the path of java and classpath.<\/i><\/p>\n

\"javaprogramming<\/a><\/p>\n

Now the path is set temporarily, I need to set the path and classpath permanently so I don’t have to type every time.<\/em><\/p>\n

Right-click mycomputer –>properties–>system protection–>advanced–>Environment Variables and add PATH and CLASSPATH with the java sdk bin address with “;”\u00a0<\/em><\/p>\n

Add PATH<\/em><\/p>\n

\"Computer<\/a>\u00a0 \u00a0 \u00a0\"System<\/a><\/p>\n

\"Add<\/a>\u00a0 \u00a0 \u00a0\"PATH<\/a><\/p>\n

Add CLASSPATH<\/em><\/p>\n

\"CLASSPATH<\/a>\u00a0 \u00a0 \u00a0\"PATH<\/a><\/p>\n

No more setting PATH or CLASSPATH<\/em><\/p>\n

\"PATH<\/a><\/p>\n
