Comparing Strings with serialEvent

Using Arduino Programming Questions

About String initialization, I've just tried this:

String str1("first string");
String str2("second string");

void setup() {
    Serial.begin(115200);    
}


void loop() {
    Serial.print("str1=");
    Serial.println(str1);
    Serial.print("str2=");
    Serial.println(str2);
    
    delay(2000);
}
