java - 构造函数声明中存在语法错误 : '{' expected

Question

我不明白我对这个构造函数做错了什么:

  public class Student(String first_name, String last_name, int home1, int home2,int quiz1, int quiz2, int quiz3, int exam1, int exam2)
  {
    fname=first_name;
    lname=last_name;
    hw1_grade=home1;
    hw2_grade=home2;
    quiz1_grade=quiz1;
    quiz2_grade=quiz2;
    quiz3_grade=quiz3; 
    exam1_grade=exam1;
    exam2_grade=exam2;
  }

编译器说:需要“{”。另外:<标识符>预计它会一遍又一遍地显示此错误

Answer 1

public class Student {
    private String fname;
    private String lname;
    private int hw1_grade;
    private int hw2_grade;
    private int quiz1_grade;
    private int quiz2_grade;
    private int quiz3_grade;
    private int exam1_grade;
    private int exam2_grade;

    public Student(String first_name, String last_name, int home1, int home2, int quiz1, int quiz2, int quiz3,
            int exam1, int exam2) {
        fname = first_name;
        lname = last_name;
        hw1_grade = home1;
        hw2_grade = home2;
        quiz1_grade = quiz1;
        quiz2_grade = quiz2;
        quiz3_grade = quiz3;
        exam1_grade = exam1;
        exam2_grade = exam2;
    }
}
