一道想不通的题
package org.dothwinds.date;
import java.util.Calendar;
public class Student {
public static final Student STUDENT = new Student();
private final int age;
private final static int Brithday = Calendar.getInstance().get(Calendar.YEAR);
private Student() {
age = Brithday - 1983;
}
public int MyAge() {
return age;
}
public static void main(String[] args) {
System.out.println( "The Student age is " + STUDENT.MyAge());
}
}
最后答案The Student age is -1983
但是去掉static就是24（也就是想要的结果）
不明白为什么~~
请教了~
[解决办法]
因为静态数据是首先按顺序载入的
所以在载入
public static final Student STUDENT = new Student();
时，还没伦到
private final static int Brithday = Calendar.getInstance().get(Calendar.YEAR);
所以i为0，然后赋给final的age，所以age=0-1983
