Variables are containers for storing data values.
In Java, there are different types of variables, for example:
String - stores text, such as "Hello". String values are surrounded by double quotes int - stores integers (whole numbers), without decimals, such as 123 or -123 float - stores floating point numbers, with decimals, such as 19.99 or -19.99 char - stores single characters, such as 'a' or 'B'. Char values are surrounded by single quotes boolean - stores values with two states: true or false
To describe each characteristic of a particle separately Arrays are used [Array] (https://vscode.dev/github/gmandroroshe/java-for-beginners/blob/main/arrays)
