如何在此 Java 程序中获取 Null 值

问：

package home;

public class Home {
    String HomeName = null;
        int room = 0;
        int kitchen = 0;
        int bathroom =0;
    
    //Constructor
    Home(String HomeName){
        System.out.println(HomeName);
    }
    Home(String HomeName, int rooms, int k ,int bathroom){
        System.out.println(HomeName+":rooms:"+rooms+":kitchen"+k+":bathroom"+bathroom);
        this.HomeName = HomeName;
        this.room = rooms;
        this.kitchen = k;
        this.bathroom = bathroom;
    
    }
    public void finaloutputhome(){
        System.out.println("Your Home Name:"+HomeName);
        System.out.println("Rooms Count:"+room);
        System.out.println("kitchen Count:"+kitchen);
        System.out.println("Bathroom Count:"+bathroom);
    
    }
        
    public static void main(String[] args) {
        
        Home obj2 = new Home();
        obj2.finaloutputhome();
        
        
    }
    
}

错误代码==>

*跑：

Exception in thread "main" java.lang.RuntimeException: Uncompilable code - no suitable constructor found for Home(no arguments)
    constructor home.Home.Home(java.lang.String) is not applicable
      (actual and formal argument lists differ in length)
    constructor home.Home.Home(java.lang.String,int,int,int) is not applicable
      (actual and formal argument lists differ in length)
    at home.Home.main(Home.java:1)

我需要的输出===>>
