Java 如何打印具有参数的对象数组？

好的，这很简单

我需要在特定索引处打印出对象的所有参数。但是，所有对象都显示内存地址。我知道你必须重写toString方法。但我不太确定在哪里

任何帮助都会很好

这是我的员工类别代码：

public class Employee {

private String name;
private int age;
private String department;

public String getDept(){
    return department;
}//end dept

public void setDept(String dept){
    this.department = dept;
}//end

public String getName(){
    return name;
}//end name

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

public int getAge(){
    return age;
}//end age

public void setAge(int a){
    this.age = a;
}//end

public Employee (String n,int age,String dept){

    this.name = n;
    this.age = age;
    this.department = dept;

}//end employee

}//末级

以下是我的主要方法中的代码：

public class Company {


public static void main(String [] args){

    Employee[] e = new Employee[13];

    e[0] = new Employee("Counting Guru",55,"Accounting");
    e[1] = new Employee("Counting Pro",45,"Accounting");
    e[2] = new Employee("Counting Savvy",40,"Accounting");
    e[3] = new Employee("Counting Novice",25,"Accounting");
    e[4] = new Employee("Sales Guru",50,"Marketing");
    e[5] = new Employee("Sales Pro",48,"Marketing");
    e[6] = new Employee("Sales Savvy",38,"Marketing");
    e[7] = new Employee("Hiring Guru",58,"Human Resrouces");
    e[8] = new Employee("Hiring Pro",47,"Human Resrouces");
    e[9] = new Employee("Hacking Pro",47,"Information Systems");
    e[10] = new Employee("Hacking Guru",51,"Information Systems");
    e[11] = new Employee("Hacking Savvy",38,"Information Systems");
    e[12] = new Employee("Hacking Novice",23,"Information Systems");


    for(int i = 0;i<e.length;i++){
        System.out.println(e[i]);

    }//end 
}//end main
}//end company

将toString放在Employee类中，上面可能有@Override标记

@Override
public String toString() {
    return name + ", " + age + ", " + department;
}

将toString放在Employee类中，上面可能有@Override标记

@Override
public String toString() {
    return name + ", " + age + ", " + department;
}

现在只需在employee数组上循环，并打印employee对象

现在，只需在employee数组上循环，并按您已有的方式打印employee对象。

完全正确。但是我想打印出所有参数，因此我不确定如何实现toString方法。返回一个包含所有要打印的参数的字符串。请准确地执行。但是我想打印出所有参数，所以我不确定如何实现toString方法。返回一个包含所有要打印的参数的字符串。我想打印出所有3个参数，那么我该如何做呢？我知道您必须返回要显示的变量，但我有3个不同类型的变量/我想打印出所有3个参数，那么我该怎么做？我知道您必须返回要显示的变量，但我有3个不同类型的变量/
