Hi everybody, I have the following code


public class AutoBoxingObj {

Integer y = new Integer(567);
Integer x = y;
System.out.println(y==x);
}

but when I try System.out.println(y==x); I get the following compiler error:

cannot find symbol
symbol: class out
location: class java.lang.System

<identifier> expected

cannot find symbol
symbol: class y
location: class AutoBoxingObj

<identifier> expected


And I don't undertand what's going on ...please some help.

You need to place your code inside of a method(most likely the main method) in order for it to function the way you want it to.
