What are the different types of References in Java?

Comment

In Java, there are four types of references:

1. Strong Reference

2. Soft Reference

3. Weak Reference

4. Phantom Reference

import java.lang.ref.*;
class Gfg
{
    //code
    public void x()
    {
        System.out.println("GeeksforGeeks");
    }
}
  
public class Example
{
    public static void main(String[] args)
    {
        //Strong Reference
        Gfg g = new Gfg();     
        g.x();
        ReferenceQueue<Gfg> refQueue = new ReferenceQueue<Gfg>();
        PhantomReference<Gfg> phantomRef = null;
          
        phantomRef = new PhantomReference<Gfg>(g,refQueue);
        g = null; 
        g = phantomRef.get(); 
        g.x();
    }
}
