Why results are different

Report a typo

Given two snippets of code with the Boolean class.

Boolean true1 = true;
Boolean true2 = true;
System.out.println(true1 == true2); // true

Boolean true1 = new Boolean(true);
Boolean true2 = new Boolean(true);
System.out.println(true1 == true2); // false

Why results are different?

Select one option from the list

This strange behavior is due to the fact that Boolean is a primitive type

Comparing reference types using == always return a random result

In the first case, the same cached object is used while in the second case new objects are always created

In the first case, the equals is implicitly called for two different objects
