the == operator will only return true when comparing two object when they are the same object...ie (name == name) will always be true but (name == "sam") will always be false...because "sam" is implicitly another string object. also,
Code:String name = "sam";
String name2 = name;
if (name == name2) { //will be true because they point to the same object
}

what you want is name.equals("sam")...it will be true when the strings are the same.
