Codecademy Learn Java tutorial walkthrough 10: relational operators
Codecademy basics tutorials always cover relational operators for each programming language taught. Relational operators refer to the !=, >, ==, <= in (5!=3) or (5>3) or (5==5) or (5 <= 7). Each is a test to see if the left and right side of the relational operator has the said relation. For example, 5!=3 will evaluate to true because it is testing for whether it is true 5 doesn't equal to 3, and that is indeed the case, so the result is true. What about (5==3)? It tests if 5 equals to 3, and the answer is no so it evaluates to false. The result of a statement with a relational operator almost always only returns only true or false. Do you remember what's the name of the data type that can only be true or false? Yes a Boolean. A Boolean can either be true or false. Why are relational operators useful?
For example in the previous exercise, we used Modulo to see if z % 2 is zero, which means z is even. We can ask the program to do something only of z is even. Below so the pseudo code to do that (pseudo code is descriptive English words that explains what the code which is yet to be written is intended to do).
if ( (z % 2) ==0) print "z is even!"
This code reads first calculate z % 2, and if that is 0, print out a message saying z is even
