Thread: 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();
}

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


} // end of amount method

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;
}
