如何从Java中的方法中选择多个不同类型的值并在主类中使用它？

Question

I have made a method which I will use several times in my main, but change the paremeters each time. I cannot figure out how to call each different values from that method. below is what I have so far for my method, it contains type Strings, int and JLABEL.

private static void method(String a, int b, int c, int d, String e, JLabel f) {
    try {
        a = (String) field1.getText();
        b = (int) (Double.parseDouble(studentid.getText());
        c = (studentname.getText()));
        d = (Integer.parseInt(hourtravel.getText()));
        countCommandsAdded.setText("e");
        contentPane.remove(f);
    }catch (NumberFormatException arg0){

    }   

}

How can I return, in this case I need to return String a, int b, int c, int d, and remove JLabel f from my design and change text of String e.

Thanks.

You can have methods with the same name in the same class, with different parameters, and different return types. This is called Overloading and it is better explained here http://docs.oracle.com/javase/tutorial/java/javaOO/methods.html .

In your case, though it is not the most brilliant solution, you can have multiple method(...) with the parameters you want, performing different logic.

As other poster suggest, a better, more OOP compliant solution would be to use generics , or to use a class as wrapper for your different values.
