    Default Can someone help me to bring just a variable from one method to another?

    I need to get the "math" variable into another method. any help would be appreciated.

    public static void Amount()
    {
    Scanner input = new Scanner(System.in);

    double initialAmount;
    double paycheckAmount;

    // user inputs the initial amount that is in their bank account

    System.out.println("Please enter your initial amount in you bank account.");
    initialAmount = input.nextDouble();
    input.nextLine();

    // dont let user input a negative value

    while(initialAmount < 0)
    {
    System.out.println("That is an invalid Value, please enter a valid value.");
    System.out.println("Please enter your initial amount in you bank account.");
    initialAmount = input.nextDouble();
    input.nextLine();
    }
    // user inputs the amount of their paycheck, that amount gets added to the initial amount

    System.out.println("Please enter your paycheck amount.");
    paycheckAmount = input.nextDouble();
    input.nextLine();

    // dont let the user input a negative value

    while(paycheckAmount < 0)
    {
    System.out.println("That is an invalid Value, please enter a valid value.");
    System.out.println("Please enter your paycheck amount.");
    paycheckAmount = input.nextDouble();
    input.nextLine();

    System.out.println("You have " + math + " dollars in your bank account");

    You can either return the variable from the Amount() function, or make it a class-level variable:

    public static double Amount() {
     ...
     double math = initialAmount + paycheckAmount;
     return math;
    }

    Or:
    private static double math;
    public static void Amount() {
     ...
     math = initialAmount + paycheckAmount;
    }
