How is HashCode generated for string variables in Java?

Question

Java

Can we hope for the uniqueness of the number if the string is different?

String A = "AA";
String B = "BB";
String a = "aA";
// Всегда должно быть - "A.Equals(a) = false";

Answer 1

1. If you install raw Java, you can see the sources.
2. At the expense of uniqueness, I don’t remember exactly, but everything seems to be as you need. But it is better to look in the raw.
3. The uniqueness of the hash can be taken as the address of the object (for example, the this variable with casting for the type).

Answer 2

But it's enough to go into the String class and see. Even in the javadoc it is displayed.
