Why did you install netbeans if you want to compile & run from the command prompt?

What happens when you type 'javac' at the command prompt?

first change the dir to the location of saved .java file using the cd on your terminal application or command prompt.
then type javac "asdf.java" whatever, then type java "asdf" and it will run

I installed netbeans for compiling java program but after knowledge of java program through command prompt then.Dear friend I saved java program in D location as D:\mywork , When I used command prompt to write d: & enter then get the information D:\> but from here i am facing problems to use command prompt for compilation & run.

Okay but where I save the java program has saved in D location.Shall I save the program in C drive?U please tell me all steps....

first the HelloWorld needs to be in file of same name, you have Helloword.java should be HelloWorld.java
once you have renamed it, type at the prompt

Code :

---

d:\mywork>javac HelloWorld.java

---

Java is case sensitive.

next type: java helloworld
and you should have it.

Go in the directory where your jdk is installed.
Place your .java file in bin folder located inside jdk folder.
Go to command prompt and move to jdk\bin directory
And then write javac className.java
java className

Or set your environment variables such as JAVA_HOME, CLASSPATH

Place your .java file in bin folder located inside jdk folder.

Only for testing. Do not leave any of your files in the JDK folder.
