why am i getting the error of below code ;

Question

Here's the program in which I am getting an error:

// import Scanner Class import java.util.Scanner;

// creating ClassStudent1
class ClassStudent1 {

    // creating instance variable for ClassStudent1 class
    int id;
    String name;

}

// creating another class in which main() will be present
class Student2{

    // creating main() method
    public static void main(String[] args) {

        // creating Scanner Class object
        Scanner sc=new Scanner(System.in);

        // creating ClassStudent1 object
        ClassStudent stu = new ClassStudent();

        // asigning value to the ClassStudent1 object stu
        stu.name="jay";
        stu.id=1023;

        // printing the value which is asign to the object
        System.out.println(stu.id);
        System.out.println(stu.name);

        // asigning value to the Scanner Class object
        System.out.println("enter your name");
        String b=sc.nextLine();

        System.out.println("enter your id");
        int a=sc.nextInt();

        stu.id = a;
        stu.name = b;

       System.out.println("your id is:",a);
      //  System.out.println("your name is:",b);

        System.out.println(a);
        System.out.println(b);
    }
}

these are the errors that I am getting:

Answer 1

Your error is in this line:

System.out.println("your id is:",+a);
