                Scanner scanner = new Scanner(System.in);
                int eid,sid;
                String ename;
                System.out.println("Enter Employeeid:");
                eid=scanner.nextInt();
                scanner.nextLine(); //This is needed to pick up the new line
                System.out.println("Enter EmployeeName:");
                ename=scanner.nextLine();
                System.out.println("Enter SupervisiorId:");
                sid=(scanner.nextInt());  
        }
}

调用nextInt（）是一个问题，因为它没有'拿起新线（当你按下回车键）。因此，在此之后调用scanner.nextLine（）可以正常工作。

Calling nextInt() was a problem as it didn't pick up the new line (when you hit enter). So, calling scanner.nextLine() after that does the work.
