Java: In Eclipse, is it possible to show an instance variable's name while debugging one of it's methods?

I've pasted the classes relevant to my question below. vis2 is an instantiated version of the Connect2 class. When debugging, if I'm in the Connect class, and then jump into the vis2.setURL(String url) method, this is listed in the Variablesview. The value for this is listed as Connect2 (id=22).

Is it possible to have Eclipse show WHICH instance of Connect2 this is describing (in this case vis2)? Thanks in advance.

Main.java

public class Main {
  public static main(String[] args) {
    Connect connect = new Connect();
    connect.findLocid();  
  }
}

Connect.java

public class Connect {
  public void findLocid(){
    Connect2 vis2 = new Connect2();
     vis2.setURL("Https://www.someurl.com");
     vis2.execute();
  }
}

Connect2.java

public class Connect2 {
  private String url;
  public Connect3 me;

  public void execute() {
    me = new Connect3(this.url);
    me.connect();
  }

  public void setURL(String url) {
    this.url = url;
  }
}

One way you could fix this problem is to add a name variable to each of your classes. For example, Connect2 could be modified as such:

public class Connect2 {
    private String url;
    public String name;
    public Connect3 me;
    public Connect2(String name) {// and the rest of your arguments
        this.name = name;
    }
    public void execute() {
        me = new Connect3(this.url);
        me.connect();
    }
    public void setURL(String url) {
        this.url = url;
    }
}

Then you can simply use the name as follows.

Connect2 <variable name> = new Connect2(<variable name>);//+ the rest of your arguments

Then you can easily find the value of the name variable.
