Simple Java GUI (Graphical User Interface)

Simple Java GUI:

In this blog, we will learn about how to create a simple input dialog box in Java. For this we need to import the library javax.swing.JOptionPane. [Solve JOptionPane error in Eclipse]

Example 1- Input Value is String.

package com.java_tutorial;

import javax.swing.JOptionPane;

public class Gui_example {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		
	     String web_name = JOptionPane.showInputDialog("Enter Your Website Name");
	     JOptionPane.showMessageDialog(null, "Hi.... " + web_name);
	
  }

}

Output:

Example 2- Input Value is Integer.

package com.java_tutorial;

import javax.swing.JOptionPane;

public class Gui_example {

	public static void main(String[] args) {
		// TODO Auto-generated method stub 
		
	     int web_traffic = Integer.parseInt(JOptionPane.showInputDialog("Enter Your Website Traffic"));
	     JOptionPane.showMessageDialog(null, "Your Website Traffic Is.... " + web_traffic);
	
  }

}

Output:

Example 3- Input Value is Double.

package com.java_tutorial;

import javax.swing.JOptionPane;

public class Gui_example {

	public static void main(String[] args) {
		// TODO Auto-generated method stub 
		
	     double web_speed = Double.parseDouble(JOptionPane.showInputDialog("Enter Your Website Speed"));
	     JOptionPane.showMessageDialog(null, "Your Website Speed Is.... " + web_speed+ " ms");
	
  }

}

Output:

Simple Java GUI Source Code: When you run the code it asks you for input one by one.

package com.java_tutorial;

import javax.swing.JOptionPane;

public class Gui_example {

	public static void main(String[] args) {
		// TODO Auto-generated method stub 
		
	     
		 String web_name = JOptionPane.showInputDialog("Enter Your Website Name");
	     JOptionPane.showMessageDialog(null, "Hi.... " + web_name); 
		
		 int web_traffic = Integer.parseInt(JOptionPane.showInputDialog("Enter Your Website Traffic"));
	     JOptionPane.showMessageDialog(null, "Your Website Traffic Is.... " + web_traffic);
		
		 double web_speed = Double.parseDouble(JOptionPane.showInputDialog("Enter Your Website Speed"));
	     JOptionPane.showMessageDialog(null, "Your Website Speed Is.... " + web_speed+ " ms");
	
  }

}
