String.equals()
Description
Compare l'égalité de deux objets String. La comparaison est sensible à la casse, ainsi le String "hello" n'est pas égal au String "HELLO".
Syntaxe
string.equals(string2)
Valeurs Renvoyées
- true: si l'objet string est égal à l'objet string2
- false: si ce n'est pas le cas
Exemple
void setup() {
Serial.begin(9600);
String myString = "Arduino";
if (myString.equals("Arduino"))
Serial.println("Two strings is equal to each other");
else
Serial.println("Two strings is NOT equal to each other");
}
void loop() {
}
The result on Serial Monitor:
COM6
Two strings is equal to each other
Autoscroll
Clear output
9600 baud
Newline
※ Remarque:
If the string is modified, it is highly recommended using String.reserve() to prevent the memory fragmentation issue
