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)

Paramètres

  • string: une variable de type String()
  • string2: une autre variable de type String()

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

※ Remarque:

If the string is modified, it is highly recommended using String.reserve() to prevent the memory fragmentation issue
