Need help with user input/output for GUI.

//This is my code so far. I'm suppose to have the user enter this:

user enters a int between <= 12 then would display this message Howdy youngster

user enters a int between >12 and <20 then would display another message displays You're getting old. etc..





I dont know how to set it up so the number i enter coordinates with the right message.





public class L4_SimpleCalc
{
public static void main (String arg[] )
{
JOptionPane.showMessageDialog(null, "The Old Man says:");

//Read in a value
String enterNum = JOptionPane.showInputDialog(null, "What is your age?:");

//convert string to a number
double num1 = Double.parseDouble(enterNum);

JOptionPane.showMessageDialog(null, "Howdy youngster!");
JOptionPane.showMessageDialog(null, "Howdy, you're on your way!!");
JOptionPane.showMessageDialog(null, "Howdy, you're a mover and a shaker!");
JOptionPane.showMessageDialog(null, "Howdy, old timer!");






























}


}

Sounds like a job for some if statements.

The if-then and if-then-else Statements (The Java™ Tutorials > Learning the Java Language > Language Basics)

import javax.swing.*;
public class L4_SimpleCalc
{
public static void main (String[] args)
{
JOptionPane.showMessageDialog(null, "The Old Man says:");

//Read in a value
String enterNum = JOptionPane.showInputDialog(null, "What is your age?:");


int age;
char text;

if (age <= 12){
text = "Howdy uoungster!";
} else if (age >12 and <20){
text = "Howdy, you're on your way!!";
} else if (age >=20 and <40){
text = "Howdy, you're a mover and a shaker!";
} else if (age >=40){
text = "Howdy, old timer!";
} else {
text = "too old";

}


}

This still isnt right but im on the right track I need it to work like that. how do i enter a value and have it come out in GUI with the right message?

When do you set age? What do you do with enterNum?

im lost..bad. I just wanna be able to enter a number and have that number go to the correct statement. if you could guide me out a little bit it would be a better learning process.

If you figure out the answers to the question I asked you, you'll figure out why you're getting compiler errors.
