How to use the java classes code example

Example 1: java class

public class Lightsaber {
  // properties
  private boolean isOn;
  private Color color;
  
  // constructor
  public Lightsaber(Color color) {
    this.isOn = false;
    this.color = color;
  }
  
  // getters
  public Color getColor() {
    return color;
  }
  public boolean getOnStatus() {
    return isOn;
  }
  
  // setters
  public void turnOn() {
    isOn = true;
  }
  public void turnOff() {
    isOn = false;
  }
}



// Implementation in main method:
public class test {
  public static void main(String[] args) {
    Lightsaber yoda = new Lightsaber(green);
    yoda.turnOn();
  }
}

Example 2: how to make a class in java

// Public creates avaliability to all classes/files
public class Object {
  // Instance of a variable per each class created
  public int a = 1;
  // Private restricts in local space (within these brackets)
  private int b = 5;
  
  // Defaults as public
  int c = 0;
  
  // Method Examples
  void setB(int B)
  {
  	b = B;
    // No return b/c 'void'
  }
  int getA()
  {
    return b;
    // Return b/c 'int' in front of method
  }
}
