1 <p>This code compares <code>java.lang.String</code> objects for reference
2 equality using the == or != operators.
3 Unless both strings are either constants in a source file, or have been
4 interned using the <code>String.intern()</code> method, the same string
5 value may be represented by two different String objects. Consider
6 using the <code>equals(Object)</code> method instead.</p>
