The problem isn't with your understanding of == and equals(); it's a question of what you're printing out.
So let's say i and j are two different objects. That means that the condition in your first if would be false. Therefore you print the boolean value of i!=j, as opposed to the String "i!=j". Since i is NOT == j, the expression i!=j is true. That's what gets printed: "true".
You can collapse that first if/else with its two println() statements into just a single...
You have a similar problem with the second if. Let's say i="Ryan" and j="Shiva". The expression in the if will be false, so it goes to the else part. There it prints out the value of the expression !i.equals(j). Since i.equals(j) is false, NOT i.equals(j) is true. So "true" gets printed.
Just replace that whole if/then with...
