How to understand this code?

Question

Java

Hello everyone, I have the following code snippet

public static final ParseTree NULL_PARSE_TREE = new ParserRuleContext() {
        @Override
        public String getText() {
            return null;
        }
    };

please tell me what is happening in it?

Answer 1

A static final field named NULL_PARSE_TREE of type ParseTree is created and given an instance of the ParseRuleContext class with the getText method overridden to always return null.
Why is another question that cannot be answered without context.
