How to Use Java - JOptionPane Input Dialog

Java Input Dialog is a part of java Option Pane that allows user to input any character into the form. every character given there will become a String data type. Java Input Dialog used for program when needed a respond from user, like's asking for feedback, answer, confirmation, and more.

Then here's the simple program that use JinputPane, don?t missed to include import javax.swing.JoptionPane:

Java:

import javax.swing.JOptionPane;
public class tryJInputPane {
public static void main(String[]args){
JOptionPane.showInputDialog(null);
}
}

Program will works, but it?s doesn?t give you any result to the output because the code above just to display the input dialog. To get value when user giving input any character to your input dialog, add a String data type beside your JoptionPane syntax.

Java:

import javax.swing.JOptionPane;
public class tryJInputPane {
public static void main(String[]args){
//every character that typed in the JOptionPane will stored into "Data"
String Data = JOptionPane.showInputDialog(null);
//print "Data"
System.out.println("Your Input : "+Data);
}
}

You may use more features from JoptionPane, like?s add a description, title for your OptionPane, and message type, and here?s the example :

Java:

String Data = JOptionPane.showInputDialog(null,"[write any description here]", "[title frame]", JOptionPane.PLAIN_MESSAGE);
