Try the following code.
public class booleantest
{
public static void main(String argv[])
{
Object obj = null;
if (obj instanceof Boolean)
System.out.println("failed");
else
System.out.println("passed");
}
}
It prints 'passed'. Although you can cast a null object to any type
by itself it is of the null type and an instanceof comparison fails.
