Man. Please listen to my voice. In this life, in my university day, maybe I am too stupid or what but I didn’t care. I get 92 out of 100 for Java Programming 1.
Haha… it is still ‘1’ rite, not yet Java Programming 2 or Java Web Programming. But men, please listen.
Twos complement is one of the building block for Computer Organization and Architecture to get an A+. To study the twos complement, you need a 1 pound of XOR logical rules in your ingredients.
What is XOR operation? XOR is a logical, boolean, operator to let you get ‘1’ if either of values but not both is ‘1’, and ‘1’ is representing a true value. Now imagine XOR in its simplest way like this.
Classmate of mine–is not actually a classmate, but can be said classmate because at that time I enter the class that not belong to my (even though the same Java class) and one of them did–said: “This class should not be called Java 2, should be Java 10, or Java 100”. All laugh.
Yeah, no one can deny that the logic in polymorphism was not easy at the first time. Even the most advanced programmer had time to imagine what the hell was that. Come’on, don’t said you understand Pythagoras, Algebra, chemical equilibrium since you were 5th grader. Gosh!
Okay okay. Then how we can learn it the easiest way?
