How to get an InputDialog box to accept two values successively

package javaapplication4;
import javax.swing.*;

public class JavaApplication4 {


    public static void main(String[] args) {
        // TODO code application logic here
        int num1;

        num1 = Integer.parseInt(JOptionPane.showInputDialog("Please enter a value"));
            if(num1<50 && num1>100)
                System.out.println("value is correct");
            else 
                System.out.println("value is incorrect");

Solution 1

You can repeat the operation 2 times like this :

public static void main(String[] args) {
    int i = 0, n = 2;//repeat n time
    while (i < n) {
        // TODO code application logic here
        int num1;

        num1 = Integer.parseInt(JOptionPane.showInputDialog("Please enter a value"));
        if (num1 < 50 && num1 > 100) {
            System.out.println("value is correct");
        } else {
            System.out.println("value is incorrect");
        }
        i++;
    }
}

Solution 2

You can use an array to store your values and check them later for example :

public static void main(String[] args) {
    int i = 0, n = 2;

    // TODO code application logic here
    int num1[] = new int[n];

    while (i < n) {
        num1[i] = Integer.parseInt(JOptionPane.showInputDialog("Please value " + (i+1)));
        i++;
    }
    if (num1[0] < 50 && num1[1] > 100) {
        System.out.println("value is correct");
    } else {
        System.out.println("value is incorrect");
    }
}

This will ask you for the n value, in your case will ask you to enter 2 values so it will stored in your array, then you can check this values of array.

EDIT

You have to use a separator and you can split with this separator for example your input should look like this :

6999,888
--1---2

so when you split with , String[] spl = res.split(","); you will get an array of String like [6999,888], then you can use this two value to make your condition :

int v1 = Integer.parseInt(spl[0]);//convert String to int
int v2 = Integer.parseInt(spl[1]);//convert String to int

So your program should look like this :

public static void main(String[] args) {
    String res = JOptionPane.showInputDialog("Please enter a value separated with , :");
    String[] spl = res.split(",");
    System.out.println(Arrays.toString(spl));
    //you have to make some check to avoid any problem
    int v1 = Integer.parseInt(spl[0]);
    int v2 = Integer.parseInt(spl[1]);

    if (v1 < 50 && v2 > 100) {
        System.out.println("value is correct");
    } else {
        System.out.println("value is incorrect");
    }
}

Edit2

You can show your result in JOptionPane like this :

if (v1 < 50 && v2 > 100) {
    JOptionPane.showMessageDialog(null, "value is correct");
} else {
    JOptionPane.showMessageDialog(null, "value is incorrect");
}

EDIT3

To get the max you have to check it like this :

if (v1 > v2) {
    JOptionPane.showMessageDialog(null, "larger value is : " + v1);
} else {
    JOptionPane.showMessageDialog(null, "larger value is : " + v2);
}

Or in one line you can use :

JOptionPane.showMessageDialog(null, "larger value is : " + (v1 > v2 ? v1 : v2));
