>From the String source (I'm getting too used to sniff inside Sun's code to
see what it is doing):
public boolean equals(Object anObject) {
if (this == anObject) {
return true;
}
if (anObject instanceof String) {
String anotherString = (String)anObject;
int n = count;
if (n == anotherString.count) {
char v1[] = value;
char v2[] = anotherString.value;
int i = offset;
int j = anotherString.offset;
while (n-- != 0) {
if (v1[i++] != v2[j++])
return false;
}
return true;
}
}
return false;
}
Not too bad if the compared strings don't have the same length. Anyway I
think switch will be always better than if...else.
IMHO I use to work only with int and translate them to String only for
printing and for input.
