Basic Input program

One way of getting input from a user is to use stuff already built into java, and this is known as a scanner. A scanner takes input from a user (keyboard) and stores it as a variable.

// we need to import the Scanner, if we
// don't import it, we cannot use it.
import java.util.Scanner;

class jamesprogram {

	public static void main(String args[]){
		// make variable that will hold the input from
		// the keyboard. So whatever we input into
		// the system, will be stored in the variable 
		// froggy
		Scanner froggy = new Scanner(;

The use of nextLine() after froggy. causes the program to wait until it receives input from froggy (i.e. the system has received input)
