java中关于数组作函数的疑问

[夜半微凉]

class Student {
    private String studentName;
    private String[] courseName;
    private int[]  courseScore;
    public Student(String studentName,  String[] courseName,int[] courseScore;) {
        this.studentName = studentName;
        this.courseName = courseName;
        this.courseScore = courseScore;
    }
    private int sum() {
        int sum = 0;
        for(int i=0; i<courseScore.length; i++) {
            sum += courses[i];
        }
        return sum;
    }
    private double avg() {
        return this.sum() / courses.length;
    }
    public void printStudentInfo() {
        System.out.println("StudentName:\t\t" + studentName);
        for(int i=0; i<courseScore.length; i++) {
            System.out.println(courseName[i] + ":\t\t" + courseScore[i]);
        }
        System.out.println("TotalScore:\t\t" + this.sum());
        System.out.println("Average:\t\t" + this.avg());
    }
}
public class MainClass {
    public static void main(String[] args) {
        String studentName = "James.King";
        Course courseA = new Course("courseA", 60);
        Course courseB = new Course("courseB", 70);
        Course courseC = new Course("courseC", 80);
        Course courseD = new Course("courseD", 90);
        Course courseE = new Course("courseE", 100);
        String[] course = new String{"courseA","courseB","courseC","courseD","courseE"};
        int[] score = new int{60,70,80,85,90};
        Student student = new Student(studentName, course[5],score[5]);
        student.printStudentInfo();
    }
}

Student student = new Student(studentName, course[5],score[5]);
为什么调用该构造方法时无法解析？

[qery]

Student student = new Student(studentName, course[5],score[5]);

-->

Student student = new Student(studentName, course,score);

不能用数组传递吗？

[Quote=引用 1 楼 qery 的回复:]

Student student = new Student(studentName, course[5],score[5]);

-->

Student student = new Student(studentName, course,score);

正解
course[5],score[5]这两个参数传错了，应该传递数组的引用（即数组名).你把course[5]当成整个数组了，其实couuse[int x]这只是数组里的一个值。

上面有很多错误，重新编译后是这样的

public class Student {
	private String studentName;
    private String[] courseName;
    private int[]  courseScore;
    public Student(String studentName,  String[] courseName,int[] courseScore) {
        this.studentName = studentName;
        this.courseName = courseName;
        this.courseScore = courseScore;
    }
    private int sum() {
        int sum = 0;
        for(int i=0; i<courseScore.length; i++) {
            sum += courseScore[i];
        }
        return sum;
    }
    private double avg() {
        return this.sum() / courseScore.length;
    }
    public void printStudentInfo() {
        System.out.println("StudentName:\t\t" + studentName);
        for(int i=0; i<courseScore.length; i++) {
            System.out.println(courseName[i] + ":\t\t" + courseScore[i]);
        }
        System.out.println("TotalScore:\t\t" + this.sum());
        System.out.println("Average:\t\t" + this.avg());
    }

}
public class MainClass {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		String studentName = "James.King";
        String[] course = new String[]{"courseA","courseB","courseC","courseD","courseE"};
        int[] score = new int[]{60,70,80,85,90};
        Student student = new Student(studentName, course[5],score[5]);
        student.printStudentInfo();

	}

}

楼主在玩人吧!

public Student(String studentName, String[] courseName,int[] courseScore;)(你带个分号干吗?难道在你工程里面没报错!)

Student student = new Student(studentName, course[5],score[5]);

你的构造 怎么写的 放的是数组 你调用的时候 怎么的就用 数组的原数? 我真是佩服你! 玩人这样玩啊...

你String a[]=B[5]; 这样去玩玩吧 看看报错不!

String[] course = new String{"courseA","courseB","courseC","courseD","courseE"};
int[] score = new int{60,70,80,85,90};

可以这样new 出来? 你使用的是什么工具?难道这样的代码不报错?

[jacky花园]

汗~

你传的是数组中的值
而你的构造是数组的嘛
还有比我更粗心的朋友哟~~``

呵呵，晓得了

[夜半微凉]

对不起，各位，刚才是在UtralEdit中写出来的。没有编译过。有很多错误。已经修改了。4楼为正解。

那你对得起4楼吗? 结贴像你这样结贴的? 别人把你代码重新给你搞好了 得分 0?

估计那哥们以后都不会看你的贴了 如果有 拉黑的功能 你估计就进去了
