What exactly do you mean by "delete"? And `obj` is an object, not a constructor – user Sep 30 '20 at 17:14

delet, Disable the option to use obj again – Ziv Sion Sep 30 '20 at 17:16

It will eventually be automatically garbage collected if it has zero references to it. – user Sep 30 '20 at 17:17

1No, there's no way and you don't need to do it either. – Kayaman Sep 30 '20 at 17:23

You can do this.
public class Main {
public static void main(String[] args) {
{
OuterClass obj = new OuterClass();
}
// the field obj no longer exists.
String obj = "hi"; // this works as the previous `obj` doesn't apply here
}
}

Firstly I didn't DV. Secondly can you elaborate what are trying to achieve. I don't think you are deleting the object by anyhow – Zahid Khan Sep 30 '20 at 17:54

@Zahidkhan this "deletes" the reference field, but the object will still use memory until the next GC. – Peter Lawrey Oct 02 '20 at 06:12

The better option was to dereference it using `obj = null`; rather than creating a scope. – Zahid Khan Oct 02 '20 at 19:58
