Our goal in this chapter is to convince you that writing a computer program is easier than writing a piece of text such as a paragraph or an essay. Java programs in this chapter.

JOptionPane showInputDialog examples. By Alvin Alexander.

JOptionPane showInputDialog examples

Last updated: Dec 14, 2013 I thought I'd share a collection of JOptionPane showInputDialog examples today. I'll start with the easiest example first, then try to add a little complexity as we go along. First up, here's a simple JOptionPane showInputDialog example where I display a dialog that prompts a user to enter their name: import javax.swing.*; /** * JOptionPane showInputDialog example #1. * A simple showInputDialog example. * @author alvin alexander, */ public class JOptionPaneShowInputDialogExample1 { public static void main(String[] args) { // a jframe here isn't strictly necessary, but it makes the example a little more real JFrame frame = new JFrame("InputDialog Example #1"); // prompt the user to enter their name String name = JOptionPane.showInputDialog(frame, "What's your name?

") Here's what this dialog looks like when this code is compiled and run: From a UI perspective, note that the title of the input dialog this code displays simply shows "Input". Information - C++ Information. C++ - Transpose a 2d dynamic matrix. Basic Datatypes. Variables are nothing but reserved memory locations to store values.

Basic Datatypes

This means that when you create a variable you reserve some space in memory. Based on the data type of a variable, the operating system allocates memory and decides what can be stored in the reserved memory. Therefore, by assigning different data types to variables, you can store integers, decimals, or characters in these variables. There are two data types available in Java: Primitive Data TypesReference/Object Data Types Primitive Data Types: There are eight primitive data types supported by Java.

Byte: Byte data type is an 8-bit signed two's complement integer.Minimum value is -128 (-2^7)Maximum value is 127 (inclusive)(2^7 -1)Default value is 0Byte data type is used to save space in large arrays, mainly in place of integers, since a byte is four times smaller than an int.Example: byte a = 100 , byte b = -50. Javanotes 7.0, Section 2.4. Section 2.4 We have seen that it is very easy to display text to the user with the functions System.out.print and System.out.println.

Javanotes 7.0, Section 2.4

But there is more to say on the topic of outputting text. Furthermore, most programs use data that is input to the program at run time, so you need to know how to do input as well as output. This section explains how to get data from the user, and it covers output in more detail than we have seen so far. It also has a section on using files for input and output. 2.4.1 Basic Output and Formatted Outupt The most basic output function is System.out.print(x), where x can be a value or expression of any type. System.out.println(x) outputs the same text as System.out.print, but it follows that text by a line feed, which means that any subsequent output will be on the next line.
