Java instance variables initialization with method

Question

I am a little bit confused about the following piece of code:

public class Test{

  int x = giveH();
  int h = 29;

  public int giveH(){
     return h;
  }
         


        

Answer 1

It's bad practice to use a method in the field initializer. You can fix this by making h final. Then it will be initialized when the class is loaded.

import java.util.ArrayList;

public class Test {
    int x = giveH();
    final int h=29;

    final public int giveH(){
        return h;
    }

    public static void main(String args[]) {
        Test t = new Test();
        System.out.print(t.x + " ");
        System.out.print(t.h);          
    }
}
