3.4 Les Variables

So what are variables? Variables are a way to store information in our computer. The variables we define in a program can be accessed by a name we give them and the computer will determine or they will be stored in the computer’s RAM or RAM memory. From now on, a variable such as sound may be modified, in other words its content is variable. There are many types of data that we can define for our variables. Like boolean which is a Logical Value: true or false. Short, int, long which are integers, that is, numbers without commas. Float, double are semicolon numbers. Byte byte signed. And char which is a unicode character (in java code it is surrounded by single odds)
