What are the pitfalls of a Java noob? [closed]

Answer 1

There's always:

String a = "wow, not the same";
String b = "wow, not the same";
String c = new String("wow, not the same");
if (a == b) { //happens to evaluate to true, but you shouldn't do this
    ...
}
if (a == c) { //evaluates to false, which is why you shouldn't do it
    ...
}

//This is how you *should* do this
if (a.equals(b)) { //evaluates to true
    ...
}
if (a.equals(c)) { //evaluates to true
    ...
}
