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