i've been using == operator in program compare strings far. however, ran bug, changed 1 of them .equals() instead, , fixed bug. is == bad? when should , should not used? what's difference? == tests reference equality (whether same object). .equals() tests value equality (whether logically "equal"). objects.equals() checks nulls before calling .equals() don't have (available of jdk7, available in guava ). consequently, if want test whether 2 strings have same value want use objects.equals() . // these 2 have same value new string("test").equals("test") // --> true // ... not same object new string("test") == "test" // --> false // ... neither these new string("test") == new string("test") // --> false // ... these because literals interned // compiler , refer same object "test" == "test" // --> true // ... should call objects.equals() o...
