Cannot find symbol variable Keyboard...

[Alnegar]

Hi, I'm new to Java, and I started out with my first class- I'm using Jcreator LE as an IDE and well, it's giving me an error every time I compile, saying 'Cannot find symbol variable Keyboard' and pointing towards the input statements. Please can someone tell me what I'm doing wrong and how to fix it? Here's my code;

/**
*My First Class
*/


public class HelloWorld {

public static void main (String args [] ) {

String name;
int age;

System.out.print("Enter your name: ");
name = Keyboard.readString(); //Pointing at this line...

System.out.print("Enter your age: ");
age = Keyboard.readInt(); //It's pointing me at this line too...

System.out.println("My name is " + name +
" and I am " + age + " years old.");
}


}

What is Keyboard? Where and how have you used this before? Are you trying to use a Scanner object or is this in some 3rd party library that needs to be included in your program?

well, want i want to do is input the input by the user by typing from the keyboard, as i was following an example in my notes...

How is the compiler supposed to know that? The word 'Keyboard' doesn't automagically ring a bell and make the compiler generate the correct code for you.

kind regards,

Either your teacher was using and importing a 3rd party library that has a Keyboard class with static methods, or he was using a Scanner class object. Only you and your notes know for sure.

thanks all for your quick replies, i'll make sure i'll ask my teacher about it, i'll post you how it went.

Good luck. Note that if you will be using an object of the Scanner class, you'll need to change the method names to those used by Scanner objects such as nextInt() and nextLine().
