在另一种方法上访问实例变量 Java

Question

I'm trying to print the obj.age, obj.name and obj.gender on my printStuff method but I can't seem to access it. What's the right way to access it?

Here's my code:

public class myLove {
   int age;
   String name;
   char gender = 'M';
   static char status;
   static String address;
   
   public static void main(String args[]){
      myLove.address = "Tiptop ambuclao";
      myLove.status =  'S';
      
      myLove obj = new myLove();
      obj.age = 17;
      obj.name = "John Doe";
      obj.gender = 'M';
   }
   
   public void printStuff(){
       System.out.println("Name: "+name);

}

}

Answer 1

If you just want to call printStuff from the main method you can simply do this:

public static void main(String[] args) {
  MyLove myLove = new MyLove();

  // set some data here

  myLove.printStuff();
}

Old Answer:

Since your printStuff method is public, you can access it from any other class:

public class OtherClass {
  
  public static void printMyLove(MyLove myLove) {
    myLove.printStuff();
  }

}

This can be simply called from your main method like this:

public static void main(String[] args) {
  MyLove myLove = new MyLove();

  // set some data here

  OtherClass.printMyLove(myLove);
}
