Answer 1

@ECHO OFF
java -jar "Path/To/The/Jar/Whatever.jar"

I would recommend first jaring up your class(es) and providing a link to the jar.

Answer 2

If you are having:

• a class Myclass,
• with a package name of com.mycomp.util.

Then:

• use the parent dir of com e.g. c:\src
  (the folder that contains the com package),

• store the below commands in a batch file:

  cd c:\\src  
  java -cp jar1;jar2; com.mycomp.util.Myclass
  

Execute the batch file to run the Java program.

Answer 3

If you have compiled your .java file, and have the .class file, containing bytecode for your main function, then just run:

java myclass

where myclass is the module name (file has to be myclass.class).

This won't work if myclass isn't in the default package. Also, by Java conventions, it should be "Myclass" instead of "myclass" – Falsecard

Answer 4

Just use this in ur .bat file
java -classpath folderName/example.jar; com.example.package.ExampleProgram if you are placing the .bat file in the same folder with the jar, then its not necessary to mention the folderName

Answer 5

You can do the following:

1. Open a new Text File in Notepad.

2. Write the following lines of code, then saves it as "MyFile.bat"
   (Note: Save it as a .BAT File)

   @ECHO OFF
javac YourClass.java
java YourClass

3. Now double click the BAT file to execute your Java program.

Note: The BAT file and Java Class should be in the same directory.
