Unit 5 Writing Classes

Java is an object-oriented programming language.

Everything in Java is associated with classes and objects, along with its attributes and methods. For example: in real life, a car is an object.

The car has attributes, such as weight and color, and methods, such as drive and brake.

Classes are sets of objects which share common characteristics/ behavior and common properties/ attributes.

public int scoreGuess (String guess){

    int count = 0;
    //Initializes count at 0
    for (int i = 0; i <= secret.length() - guess.length(); i++) {
        if (secret.substring(i, i + guess.length()). equals(guess)) {
            count++;
        }
    }
    return count * Math.pow(guess.length(), 2);
}

public void addMembers (String[] names, int gradYear) {

    for (string n : names) {

        MemberInfo newM = new MemberInfo (n, gradYear, true);
        
        memberList.add(newM);
    }
}

Creation of Classes: should be done with UpperCamelCase and made with a key word for the class.

class MyPainter {

}

Main Method: Called automatically when a class is ran and creates an object.

class MyPainter {

    public static void main (String[] args) {
      MyPainter obj = new MyPainter();
    }
  }

The Keyword "This" helps us to see the properties of a class.

Constructor: Called when the object is created and doesn't return a value because the object is automatically called.

class MyPainter {
    int paint1;
    int paint2;
  
   
    public MyPainter (int paint1input, int paint2input) //This is a constructor

Get Methods: obtain the properties of an object beyond the defined class

class MyPainter {
    int paint1;
    int paint2;
  
   
    public MyPainter (int paint1input, int paint2input) //This is a constructor

    public int getpaint1() {
        return this.paint1;
      }
