java我的输出有一些问题

卡勒顿地区每年夏天都会举办一次小型奥运会。创建一个名为Participant的类，其中包含名称、年龄和街道地址字段。包括为每个字段分配参数值的构造函数和返回包含所有值的字符串的toString（）方法。还包括一个equals（）方法，该方法确定两个参与者在所有三个字段中的值相同时是否相等。创建一个包含两个数组的应用程序，每个数组至少包含5名参与者——一个包含迷你马拉松的参与者，另一个包含跳水比赛的参与者。提示用户两个事件中的参与者将文件另存为BC。java和ABC。爪哇

import javax.swing.JOptionPane;
import java.util.*;

public class ABC {
     private  static Participant mini[] = new Participant[2];


    public static void main(String[] args) {

        setParticipant();
        displayDetail();

    }


        // BC p=new BC(name,age,add);
    //displayDetails();
        // System.out.println(    p.toString());
    public static void displayDetail() {

        String name=null;
       String add = null;
        int age=0;

        System.out.println("Name\tAdress\tAge");
      BC p=new BC(name,age,add);
        for (int x = 0; x < mini.length; x++) {
//Participant p1=mini[x];
            System.out.println(p.toString());
        }
    }



           public static String getName() {
              Scanner sc = new Scanner(System.in);
              String name;
             System.out.print(" Participant  name: ");
              return name = sc.next();
           }

         // System.out.print(" Participant  name: ");
         // name = sc.next();
          public static int getAge() {
int age;
               System.out.print(" Enter age ");
                 Scanner sc=new Scanner(System.in);;
                return age= sc.nextInt();
          }
         public static String getAdd() {
             String add;

            Scanner sc=new Scanner(System.in);;
       System.out.print("Enter  Address: ");
       return add=sc.next(); 
         }


    public static void setParticipant(){
        for (int x = 0; x < mini.length; x++) {
         System.out.println("Enter loan details for customer " + (x + 1) + "...");
//Character loanType=getLoanType();
        //String loanType=getLoanType();
        String name=getName();
          String add=getAdd();
          int age=getAge();
         System.out.println();
        }


      }
    }

    //another class
public class BC {


    private String name;
    private int age;
    private String address;


    public BC(String strName, int intAge, String strAddress) {

        name = strName;
        age = intAge;
    address = strAddress;
    }


    @Override
    public String toString() {
        return "Participant [name=" + name + ", age=" + age + ", address=" + address + "]";
    }
public boolean equals(Participant value){
    boolean result;
    if (name.equals(name) && age==value.age && address.equals(address))
            result=true;
    else 
        result=false;
    return result;
        }





}

outPut:
Enter loan details for customer 1...
 Participant  name: hddgg
Enter  Address: 122
 Enter age 12

Enter loan details for customer 2...
 Participant  name: ddjkjde
Enter  Address: hdhhd23
 Enter age 12
//Why I'm not getting right output
Name    Adress  Age
Participant [name=null, age=0, address=null]
Participant [name=null, age=0, address=null]
