[英]why am i getting the error of below code ;
這是我收到錯誤的程序:
// 導入掃描儀 Class 導入 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);
}
}
這些是我得到的錯誤:
