如何将所有输入显示在一个JOptionPane中，而不是一次显示一个窗口？

Question

Below is my code. I am very new to Java and programming in general this is my 2nd day in class, when i run this i end up being able to only open one dialog box at a time instead of being able to input all of the data and having it all show in the dialog box. Any help would be greatly appreciated! Looking forward to learning more about programming and hopefully one day helping others.

import java.util.Scanner;
import javax.swing.JOptionPane;


public class EchoProgram {
    public static void main(String[] args) {
        byte byteValue;
        short svalue;
        int ivalue;
        long lvalue;
        float fvalue;
        double dvalue;
        char charValue;
        boolean booleanvalue;


        Scanner keyboard= new Scanner(System.in);
        System.out.println("Enter a byte value (-128 through 127)");
        byteValue = keyboard.nextByte();
        JOptionPane.showMessageDialog(null, "You have entered " + byteValue);

        System.out.println("Enter a short value (-32,768 through 32,767)");
        svalue = keyboard.nextShort();
        JOptionPane.showMessageDialog(null, "You have entered " + svalue);

        System.out.println("Enter a int value (-2,147,483,648 through 2,147,483,647)");
        ivalue = keyboard.nextInt();
        JOptionPane.showMessageDialog(null, "You have entered " + ivalue);

        System.out.println("Enter a long value (-9,223,372,036,854,775,808 through 9,223,372,036,854,775,807)");
        lvalue = keyboard.nextLong();
        JOptionPane.showMessageDialog(null, "You have entered " + lvalue);

        System.out.println("Enter a float value (number with decimals)");
        fvalue = keyboard.nextFloat();
        JOptionPane.showMessageDialog(null, "You have entered " + fvalue);

        System.out.println("Enter a double value (number with decimals)");
        dvalue = keyboard.nextDouble();
        JOptionPane.showMessageDialog(null, "You have entered " + dvalue);

        System.out.println("Enter a char value (a through z)");
        charValue = keyboard.next().charAt(0);
        JOptionPane.showMessageDialog(null, "You have entered " + charValue);

        System.out.println("Enter a boolean value (true or false)");
        booleanvalue = keyboard.nextBoolean();
        JOptionPane.showMessageDialog(null, "You have entered " + booleanvalue);
        keyboard.close();
    }
}
