对象的设置方法错误

Question

不太清楚为什么，但 eclipse 对我的 setter 方法产生错误，读取 "Syntax error, insert "...VariableDeclaratoid" to complete FormalParamaterList."

这是我的代码：

public class Student {
    public int id;
    public String name;

    Student() {

    }

    public int getID() {
        return id;
    }


    public void setID(i) {
        this.id = i;
    }

    public String getName() {
        return name;
    }

    public void setName(n) {
        this.name = n;
    }

    public String toString() {
        System.out.println("The student's name is: " + this.name);
        System.out.println("The student's ID is: " + this.id);
    }
}

Answer 1

因为你没有给你的参数 i 和 n 它们的类型。见下文

public void setID(int i) {
   this.id = i;
}



public void setName(String n) {
  this.name = n;
}
