    You need to debug the code to see what the problems are.
    Open a command prompt window and enter the java command to start the execution:
    java -jar TheJarFileNameHere.jar

    That will allow you to see any error messages written to the console.

    Copy the full text of any error messages you want help with and paste it here.

    If there aren't any error messages, then some println() statements need to be added to the code so show what the code is doing and what the values of variables are.
    If you don't understand my answer, don't ignore it, ask a question.

    Select Edit
    Select 'Select All' - The selection will show
    Click in upper left again
    Select Edit and click 'Copy'

    Paste here.

    The jar file must be in the same folder where the java command is executed. For the last post that would be:
    C:\Users\sakonpure6

    specified)
    Is that file in the jar file? If so the code must treat it as a resource and use one of getResource methods to access it.
    If it can't be in the jar file, then the Music folder must be in the same directory as the jar file.
    If you don't understand my answer, don't ignore it, ask a question.
