Input

Try the following code:

1. Open Ready to Program.
2. Open the IBIO.java file in the Unit 1 folder of the I://. Save it to the Unit 1 folder in your own space on the G://. (Or download it)
3. Open a new program in ready to program. Save it to the Unit 1 folder in your own space on the G://. Cut and paste in the following code:

  public class FirstInput
  {
   public static void main (String args [])
   {
     new FirstInput ();
   }

   public FirstInput ()
   {
   	System.out.println ("W E L C O M E");
   	System.out.println ("");
   	int a = IBIO.inputInt ("Input a number >> ");
   	System.out.println ("You have entered " + a + ".");
   	System.out.println ("");
   	String name = IBIO.inputString ("Type your name >> ");
   	System.out.println ("The name you entered is " + name + ".");
   }
 }
 

This code has a couple of new things in it.

• Two variables are declared. "a" is an integer. "name" is a string.
• We have called the class IBIO to get input for us. Ex. name = IBIO.inputString ("Type your name >> "); Note that the IBIO Class has to be saved to the same spot as the file that uses it.
• We have outputted what is in a variable. System.out.println ("The name you entered is " + name + ".");
