How to get two string input and compare them in Java?

Question

When I get two string input and compare them with two saved strings it always gives wrong result as I am using (== && ==) operators

Answer 1

String is an object so it can't be compared using boolean operators like primitive data types

Answer 2

Use equals() method if you want to compare there value and use instanceOf keyword if you want to compare there referance

Answer 3

Use variable.equals(variable2). It is case sensitive, if you want to ignore case use .equalsIgnoreCase(variable2)

Answer 4

No sorry I haven't used it often, but its System.exit(0). Look up "Java Docs" followed by a method, it's one of the best Java documentation I've found

Answer 5

"string".equals("string")
>>
true

"string".equals("string2")
>>
false

Answer 6

What about not equal !=

Great
Thanks again

Answer 8

You can't use a boolean operator when comparing contents of a string use the equals() instead. If it's case sensitive use the equalsIgnoreCase ().
