Errata - John Meyers Exam

[Najmunnisa Sageer]

Hi,

First of all let me thank for the free online John Meyers mock exam.This exam has helped me a lot in improving my generics knowledge.

In one of the mock question

class test
{
int x; test(int input) { x = input; }
public static void main( String args[] )
{
System.out.println( new test(3).equals(new test(3)) );
}
public boolean equals( Object o)
{
return ( (test)o ).x == x;//1
}
}

Its a compiler error on the line 1 and the answer is displayed as
"Prints true".

Everything is OKAY.
Compiler is happy and proper output is displayed.
