How to get textpad to compile and run java applications?
Create your java program and save it. Copy this source code file to bin folder of java (i.e where java is installed). Then open up console window by going on START->RUN->type cmd->OK A black console screen opens up. With CD command enter into the bin directory of java folder like I had java 1.6.0_10 version so I will write cd C:\program files\java\java1.6.0_10\bin and press enter after going into this directory write javac

Why can't I run a java program?
I created a package in Eclipse and ran my HelloWorld just fine from Eclipse. When I went to a command prompt and navigated to that folder and ran javac HelloWorld.java, it complied without issue. When I ran java HelloWorld, I got Error: Could not find or load main class HelloWorld I also tried java Hello.HelloWorld thinking that it might be because it had a package declaration

I've been trying to get my Java and Textpad to work together for so long on my 64 bit windows 7 OS, and after uninstalling and reinstalling about twenty times and modifying environment variables, I just don't know what to do.

What should I learn in order to make Java program?
First of all in order to make a Java program you should be a programming geek means you should know about basics of object oriented languages/* Means basic of c,c++ the difference between Procedural and Object Oriented Language what they are actually */So as a newbie try your level at core java by understanding the OOPS concept of Java. Use a perfect Java book as a guide there are many available I prefer 1) Head First Java 2)Java The Complete Reference 3) Core Java 4)Thinking in Java , I.e . Try to learn every concepts like syntax of Java and all. And as using java for the first time ,one should know what are their components . Like try to know The JDK and JRE ,latest version of Java /* JDK 8*/ and what JIT compiler is Including their heart the JVM. And even try to learn how to install the JDK setup and setting the environmental variables.Now to run a Java Program their are many ide’s available like NetBeans,Eclipse, Enide studio, Blue J, jedit, J source, Dr Java .I.eBut for a Rookie I prefer one should start using a simple text editor like notepad and try to make your first program simple by using simple java concepts. write a simple java program to print hello world and compile it using the command line.Ex:~Class Abc{System.out.println(“Hello World”);}Compile the program as > javac Abc.javaRun the program as > java AbcI prefer this might be enough for one to learn in order to do Java Programming. And give your PERFECT SHOT! ;)I hope this helps in some concerns! :)
