Converting a String to Object [closed]

Question

How can I convert a String to Object? Actually, I want to set

clientSession.setAttribute("username", "abc")

However, it shows

java.lang.String given, required java.lang.Object.

Answer 1

A Java String is an Object. (String extends Object.)

So you can get an Object reference via assignment/initialisation:

String a = "abc";
Object b = a;
