Simply create a .bat file with the following lines in it:

@ECHO OFF
set CLASSPATH=.
set CLASSPATH=%CLASSPATH%;path/to/needed/jars/my.jar

%JAVA_HOME%\bin\java -Xms128m -Xmx384m -Xnoclassgc ro.my.class.MyClass

Sure, call the java executable.

Mine is C:\Program Files\Java\jre6\bin\java.exe, so to run it I would do

C:\Program Files\Java\jre6\bin\java.exe -jar myjarfile.jar

That should be `java -jar myjarfile.jar` (your example is missing the `-jar`) – Feb 18 '13 at 17:54

It's the same way you run it from command line. Just put that "command line" into a ".bat" file.

So, if you use java -cp .;foo.jar Bar, put that into a .bat file as

@echo off

java -cp .;foo.jar Bar

echo Your class Name is %Name% & pause
echo To creat a Notepad

notepad %Name%.java

pause
javac
echo Your java Path succsussfully set.
javac %Name%.java
pause
echo Successfully Compiled
java %Name%
pause

1)open a notpad 2)copy and past this code and save this file as ex: test.bat 3)Double Click tha batch file. 4)put your java codes into the notepad and save it as N.B.:- save this java file same folder that your batch file exists.

what's the purpose of opening up notepad when you just want to compile and run? — Faahmed, Mar 29 '14 at 20:37

javac Application.java

java Application

pause

The javac command will compile the java program and the java command will run the program and pause will pause the result until you cross it.

Call the class which has main() method.

java MyClass

Here MyClass will have public static void main() method.

javac (.exe on Windows) binary path must be added into global PATH env. variable.
```
javac MyProgram.java
```
or with java (.exe on Windows).
```
java MyProgram.jar
```
