[answered] Comparising input strings (Java)

Question

I have an input (scanner.nextLine()) and I enter "ABC". Why does input=="ABC" return false?

Answer 1

Use s1.equals(s2) to compare strings:

input.equals("ABC')

Answer 2

Because String in Java is a reference type, this means that when you use the String in your program, you are actually using its reference.

"ABC" == "ABC" actually compares the references of the strings.
