I used to teach the Data Processing Class at the local Community College. Part of the curriculum was How to write java programs. We started with a blank page, wrote every line, compiled it, and tested the program. My question is what do I need to download in order to be able to waste a little time writing programs to REVERSE the order of a sentence and such. I used to spend a lot of free time playing with java. also where do I get it I think I have already downloaded a bunch of stuff from sun java but the blank page with a compiler button at the side just don't come up, I get a bunch of HTTP stuff that I don't understand and have no desire to work with. Maybe I need an old Java program. Any help will be appreciated, thanks.you could try netbeans IDE; or eclipse.

At it's core java has always simply been javac- the command line java compiler. I am not aware of any built-in tool with a "compiler button", so that was probably some other piece of software.

P.S: Java is now owned by Oracle. Somehow I don't feel that BODES well for the language.

In any case, you could always simply use notepad/ a text editor and the command-line, just like in the beginning days

create a quick test program in notepad; for example, "javatest.java":

Code: [Select]public class javatest{
public static void main(String[] ARGS)
{

System.out.println("Java test.");

}
}
And, if you installed the JDK properly, java (the VM) and javac (the compiler) should both be readily available at the command line:

Code: [Select]C:\>javac javatest.java

which, I don't doubt you already know, creates the class file:

Code: [Select]C:\>java javatest
Java test.

BC_Programmer pretty much has it covered.

Just one quick point though - if you'll be developing (/writing test programs), you'll need the Java JDK release (http://www.oracle.com/technetwork/java/javase/downloads/index.html) not the standard runtime one. This can be a common mistake since people download 'Java' (the runtime one, not the JDK) but then can't write and run programs.I just downloaded the jdk, will see what happens, thank you.Can U plaese give me some programming codes for java?
