Java programming read input format output from console and from inputbox
Using dialog box for Input and Output
Using Console output windows to prompt for Input and output is very old-fashioned . And sometimes outdated. The more current way is to create a separate pop-up windows for each input.
Call the static showInputDialog method of the JOptionPane class, and supply the string that prompts the input from the user. For example:
Read an Integer
String strNumber= JOptionPane.showInputDialog("Enter an integer number:");
The above method returns a String object.
Use the Integer.parseInt(strNumber) to convert the strNumber to an Integer intNumber
int intNumber = Integer.parseInt(strNumber) ;
Read a number with decimal points.
String strPrice= JOptionPane.showInputDialog("Enter a price:");
The above method returns a String object.
Use the Double.parseDouble(strPrice) to convert the strPrice to a double number dblPrice
double dblPrice = Double.parseDouble(strPrice) ;
Display on a messgebox
JOptionPane.showMessageDialog(null, "Price : " + price);
