Displaying Text in a Dialog Box

By -
In this program, will we be showing you how to use JAVA program to display a text using JAVA GUI (Graphics User Interface) in a dialog box.

Typically,dialog boxes are windows in which programs display important messages to the user of the program. 

This application uses Java's Class JOptionPane which provides prepackaged dialog boxes that enables programs to display windows containing messages to its user.

we will be using the import javax.swing.JOptionPane which is an import declaration and is part of the Java API. 
Programmers use import declarations to identify the predefined classes used in Java Program. The import declaration help the compiler locate the classes you intend to use, this tells the compiler that our program uses class JOptionPane from package javax.swing and this package helps programmers create graphical user interfaces (GUI) for applications.

 The program below illustrates how to create a text in a dialog box.

import javax.swing.JOptionPane;  

public class HelloWorld{

  public static void main(String args[])
  {
    JOptionPane.showMessageDialog(null, "Welcome to\nJava Programming!!");
   
    System.exit(0);
  }
}

Java applications can also be run on command prompt.  On Printing Your Fist Java Program we explain the steps with developing your first java program on command prompt.

C programming Project From Deitel C how to program (Making a difference) Create a BMI calculator application that reads the user’s weight in pounds and height in inches (or, if you prefer, the user’s weight in kilograms and height in meters), then calculates and displays the user’s body mass index.  Also, the application should display the following information from the Department of Health and Human Services/National Institutes of Health so the user can evaluate his/her BMI: BMI VALUES Underweight: less than 18.5 Normal: between 18.5 and 24.9 Overweight: between 25 and 29.9 Obese: 30 or greater One thing we generally need to know is that Bmi is universally expressed in Kg/M 2  and heights in Meters  and the formula given by; BMI weightInKilog rams --------------------------------------------- heightInMeters  ×  heightInMeters It can also be expressed in Pounds and Inches with the formula given as; ...

Adding two Integers in Java Application

This application reads (or inputs) two integers (whole numbers,) typed by a user at the keyboard, computes their sum and displays it. This program Must keep track of the numbers supplied by the user for the calculation later in the program. Programs remember numbers and other data in the computer’s memory and access That data through program elements called variables . Solution //Addition program that displays the sum of two numbers. //Java packages import javax.swing.JOptionPane; //program uses JOptionPane public class Addition{     //main method begins execution of java application   public static void main (String args[])   {     String firstNumber; //first string entered by user     String secondNumber; //second string entered by user         int number1;   //first number to add     int number2;   //second number to add ...

Calculating Product, sum, difference, and quotient of Five Integers

A simulation question is given to write an application using Java language that asks the user to enter five integers, obtains the numbers from the user and prints the product, sum, difference and quotient (division) of the numbers using the Java GUI (Graphics User Interface). In  Java, user input is normally in form of strings and not integers; so when the user inputs an integer as a string, we need to convert it to its corresponding integer by calling the integer.parseInt() method. We will also be importing the javax.swing.JOptionPane, which will be used be used for dialog boxes. in my tutorial on Comparing Two Integers in Java programming , i explained the usefulness of dialog box. import javax.swing.JOptionPane; public class Product{   public static void main (String args[])   {     int r;     int s;     int t;     int u;     int v;     int sum;     int product; ...
