Looking at the code for a class

Let's say we are making an app for the military. It is for use by senior officers to micro-manage their troops in battle. Among others, we would probably need a class to represent a soldier.

Class implementation

Here is the real code for our hypothetical class. We call it a class implementation. As the class is called Soldier, if we implement this for real, we would do so in a file called Soldier.java:

public class Soldier {
   
   // Member variables
   int health;
   String soldierType;
   // Method of the class
   void shootEnemy(){
             // Bang! Bang!
   }
   
}

The preceding is a class implementation for a class called Soldier. There are two member variables, or fields, an int variable called health, and a String variable called soldierType...
