I cant under stand when do i use equals() and when do i use == in java

Answer 1

Generally, use == for primitive data-types.
Use .equals() for Objects.

Primitive data-types in java are luckily easy to see as they have a lower case letter in the front.

Primitives:
int, double, long, short, byte, boolean, float, and char.

Answer 2

Usually we use == to get a Boolean.

But recently I have learned that:
String s1 = "myString";
String s2 = new String("myString");

s1 == s2. ---> False.

Shocking right?
In this case we would use
s1.equals(s2); ---> True.

Answer 3

== is to compare the object/primitive in memory
.equals() is for comparing the value.

Basically, if you want to compare Strings or other non-primitives use .equals(). For primitives use ==.

Answer 4

thx guyz very helpful

Answer 5

As far as I now, the == operator compares the reference of an object? Correct me if i'm wrong.
