How to compile Java
 

We all know Java compiles down into byte format which requires a JVM to run. Often for deployment we can not guarantee that our clients will have the JRE installed, nore can we supply them with a jar file. What solutions do people use to compile their Java code into native code for simple use and execution?

You can try this http://gcc.gnu.org/java/

You need jdk to compile java application

In JDK, open DOS and type..
javac filename.java
and to run/execute the file type-
java filename

You must to share path to your client.They are same path in their pc.

java class name.java

You can set path ,than after use cmd and type class name xyz.java.

If you want to compile a java file then first of all you have to set the path of that file after that you can only run any of the file available on that location by using CMD and typing "javac filename.java".

JDK is required to compile the java code using 'javac' command.

To compile java file you need to use javac command e.g. javac myfile.java
this will compile the myfile and make the .class file.

Compile Java
 

Compile Java through command line command is javac file name.java, example javac Hello.java

1st of all download JDK and install it on your PC and now you can use Windows Command prompt to run your code. Otherwise you can also use Eclips, Netbeans. For new comer I prefer Windows cmd option to run a Java code.
