Declaring Variables in Java

Storing Information

Lets look at a scenario. How should you store the following information?

1. Quest Completion

2. Player Name

3. Currency

In order to do that, first you must understand what is a variable.

Common Types of Data

• String for Text information

• Integer for Number information without decimals.

• Boolean for logical situation like True or False

Therefore, in Java. You can declare the variables like the following and print them out.

public class BasicVariables 
{
    public static void main(String[] args)
    {
        String sPlayerName = "Gladeus";
        int iCurrency = 712;
        boolean bCompletedQuest = false;
        
        System.out.println("Player Name: " + sPlayerName);
        System.out.println("Currency: " + iCurrency);
        System.out.println("Quest Completed: " + bCompletedQuest);
    }
}

Data Types

Java is a statically typed language, at compile time its variables & its data type are defined. Therefore, such variables cannot hold other data types after declaration.

So what other data types are there?
