What is up XPG Another programming tutorial and this time we will dive into what begallegal1 is studying. Java is one hell of a program, and in my adventures in College, I took a small class regarding it and enjoyed myself. However, Java was one of the programming languages I grasped rather quickly compared to most! In this tutorial we will go over the different variables and their types. This is a simple tutorial and will basically explain the differences between the two, and their role in Java. Variable: it is basically a placeholder or a identifier which would have some known or unknown information. Most of the time, it is a value. Type: A type is just a set of various types of data. We will firstly begin with the more built in basic data types. byte: (number) short: (number) double: (floating number) - i.e. 5.1, anything with a decimal involved is a floating number. long: (number) int: (number) char: (a character) - This is mostly defined as text. boolean: (True or False) Numbers: To set and put a number to a data type: int Number; Number = 5; or to be even more efficient: int Number = 5; This rule applies to most of them, and its that easy to set them. float f = 4.5; Float allows you to add a decimal to the number! Strings and Characters: For the character and well text settings: char Name = 'Iamcoolz'; Strings and how to combine them: String String1 = new String(" Hello XPG and welcome to a tutorial by:"); String String2 = new String = ("Iamcoolz"); String String3 = String1 + String2; Now looking at the above, we went over how to add numbers so let's add it a string, to make a combined sentence using a variable set by you! int MyNumberz = 365; String String1 = "There are " + MyNumberz + " days in a year"; Now Boolean is a bit more complicated, however, still rather simple. if (temperature > 75 ) { system.out.println("It is somewhat nice outside"); } Using an IF statement, you can make booleans come to life! I hope this wasn't too tough to read, I am a tad bit tired so -Iamcoolz
