        Scanner scanner = new Scanner(System.in);

        System.err.println("Please enter first number to add : ");
        int number = scanner.nextInt();

        System.out.println("Enter second number to add :");
        int num = scanner.nextInt();

        //adding two numbers in Java by calling method
       int result = add(number, num);

       System.out.printf(" Addition of numbers %d and %d is %d %n", number, num, result);
    }

    public static int add(int number, int num){

Check your pc's java version.

Java Scanner is included from a specific version.java.util.Scanner was introduced in version 1.5 ("Java 5"). Make sure you have the same the java version 1.5 or higher on your old machine.

Download new version of jvm and jre from their site and then try.
