我有这个代码
enum check
{
STUDENT ("Sireee"), ID (12354), YEAR ("1st Year"), DEP("College of Computer Studies");
private String year;
private String student;
private String dep;
private int id;
// some Constructor here
我的问题是我不知道如何在主类中获取STUDENT,ID,YEAR和DEP的值。如何能够得到这个值?
我的**期望的输出**是
父亲
12345
第一年
计算机学院

您使用错误的方式使用enum
。在您的情况下,最好使用class
Student.java
public class Student {
private int id;
private String name;
private String year; // int is prefered. since you are using string I used it.
private Department dep; // demonstrating use of enum
// getters and setters
}
现在,让我们看看如何使用enum
Department.java
public enum Department {
CSE("Computer Science Engineering"),
MEC("Mechanical Engineering")
private String name;
Department(String name) {
this.name = name;
}
public String getName() {
return name;
}
}
如果您希望现在显示值,让我们创建两个学生并显示值
public class Test {
public static void main(String[] args) {
Student s1 = new Student();
s1.setName("John Wick");
s1.setId(1);
s1.setYear("1st Year");
s1.setDepartment(Department.CSE);
Student s2 = new Student();
s2.setName("Will Smith");
s2.setId(2);
s2.setYear("2nd Year");
s2.setDepartment(Department.MEC);
System.out.println(s1.getName() + " department is " + s1.getDepartment().getName());
System.out.println(s2.getName() + " department is " + s2.getDepartment().getName());
}
}
Output
:
John Wick department is Computer Science Engineering
Will Smith department is Mechanical Engineering
