methods

[lilac87]

Hi!
I am trying to implement the following methods into the code below. The methods are: calcuateRetire() and display. I'm really new to java, so please give me some advice.

import javax.swing.JOptionPane; public class calculate {public static void main (String [] args) {
int age, retire;
age = Integer.parseInt (JOptionPane.showInputDialog("Your age?"));
retire = 65 - age;
JOptionPane.showMessageDialog(null,"You are eligible to retire in: "+ retire + " years"); }}

@IEEE please do not take peoples threads. Post your own thread for your own problems.

@OP we're going to need some more description if we are going to help. I really have no idea what you are trying to do.

I've implemented the methods, but it doesn't calculate the retiring age. I'm not sure how to fix it. I want it to calculate correctly, that's all. any advice?

import javax.swing.JOptionPane;
public class Lab2Solution
{
public static void main (String [] args)
{
age = enterAge(int age);
calculateAge();
display();
}
private static int enterAge()
{
int age;
while (age <= 0 || age >= 65)
age = Integer.parseInt (JOptionPane.showInputDialog ("Your Age?"));
return age;
}

public static int calculateRetire()
{
int age=0, retire=0;
retire = 65 - age;
return retire;
}

public static void display()
{
int retire=0;
calculateRetire();
JOptionPane.showMessageDialog(null,"You are eligible to retire in: "+ retire + " years");
}

}

Hello lilac87,

your enterAge() method does not accept any arguments but you r passing...... correct code will be;

code

import javax.swing.JOptionPane;
public class Lab2Solution
{
public static void main (String [] args)
{
int age = enterAge();
int retire=calculateRetire(age);
display(retire);
}
private static int enterAge()
{
int age;
age = Integer.parseInt (JOptionPane.showInputDialog ("Your Age?"));


return age;
}

public static int calculateRetire(int age)
{
int retire=0;
retire = 65 - age;
return retire;
}

public static void display(int retire)
{
JOptionPane.showMessageDialog(null,"You are eligible to retire in: "+ retire + " years");
}

}
