    I am trying to get selection from user from keyboard…….
    For some arithmetic operation as selected by the user……..
    After doing some operation
    I wish to ask again the user for new selection.
    As I have already put the code for user input and arithmetic operations I wish I could go back for user to input again or to quit…….

    Say I ask…..
    “Please input x for multiply z to divide or e to exit.”
    If user give input x
    I do multiply operation on the data I collected before
    Display the output and ask again
    “Do you wish some other operation y to continue or n to exit”
    If user input is y I go back to the line
    “Please input x for multiply z to divide or e to exit.” Again

    regards

    Your Problem statement is not clear for me but I will try to suggest you as per my understanding of your problem.

    For above mention case no need to use labels you can mange simply by writing the while and dowhile loops
    efficiently.

    For reference consider below template of code

    char ch;
    Scanner sc=new Scanner(System.in);
    do
    {
    /********************
    *********************
    Add your input statements
    Here read data using scanner object
    for int using sc.nextInt()
    for string using sc.next();
    for double usinf sc.nextDouble();
    and perform operations
    ********************
    ********************
    *********************
    *********************/

    System.out.println("Press Y to Continue or N to Quit");
    ch=sc.next();
    }while(ch.compareToIgnoreCase(yes)==0)

    I hope above block will helpful for you.
