java Quarterback class

Here's my program, I need to fill in the blank methods and can't figure them out. I'm using JAVA object oriented. Please help, I'm new to this so I'm kind of confused. If someone could just help me out it will be awesome, just a little help is better than none.

Description

For this program, you are to create a Quarterback class. This is a simple object that represents a quarterback in the NFL. Implement the UML diagram given below. You may create additional private methods that you feel are necessary or helpful to implement this class.

UML Diagram:

Create a Quarterback class based on the following UML diagram.

-- attempts : int The number of passing attempts made by this Quarterback.

­-- completions : int The number of passing completions made by this Quarterback.

­-- firstName : String This Quarterback’s first name.

­-- interceptions : int The number of interceptions thrown by this Quarterback.

-- lastName : String This Quarterback’s last name.

-- touchdowns : int The number of touchdowns thrown by this Quarterback

-- yards : int The number of passing yards this Quarterback has.

• Quarterback () Creates a new Quarterback object.
• Quarterback (String first, String last,

  int completions, int attempts,

  int yards, int interceptioiinint int touchdowns) Creates a new Quarterback object with the given parameters.

• copy() : Quarterback Returns a Quarterback object whose properties are identical to this Quarterback’s properties.
• equals(o : Object) : boolean Returns true if o is a Quarterback and o’s first name, last name, attempts, completions, yards, interceptions and touchdowns are all equal to this Quarterback’s corresponding properties.
• getAttempts() : int Returns this Quarterback’s number of passing attempts.
• getCompletions() : int Returns this Quarterback’s number of completions.
• getFirstName() : String Returns this Quarterback’s first name.
• getInterceptions() : int Returns this Quarterback’s number of interceptions.
• getLastName() : String Returns this Quarterback’s last name
• getRating() : double Returns this Quarterback’s NFL passer rating. The formula for NFL passer

  rating can be found at: http://en.wikipedia.org/wiki/Passer_rating.

• getTouchdowns() : int Returns this Quarterback’s number of touchdowns
• getYards() : int Returns this Quarterback’s number of passing yards.
• setAttempts(attempts : int) Sets this Quarterback’s attempts to attempts.
• setCompletions(completions : int) Sets this Quarterback’s completions to completions.
• setFirstName(name : String) Sets this Quarterback’s first name to name.
• setInterceptions(interceptions : int) Sets this Quarterback’s interceptions to interceptions.
• setLastName(name : String) Sets this Quarterback’s last name to name.
• setTouchdowns(touchdowns : int) Sets this Quarterback’s touchdowns to touchdowns.
• setYards(yards : int) Sets this Quarterback’s yards to yards.
• toString() : String Returns a String representation of this Quarterback consisting of the first name, a space, the last name, and this Quarterback’s passer rating displayed to one decimal. E.g., if q is a Quarterback object, q.toString() will return: “Aaron Rodgers 123.8”

OK. I'll give you some pointers

For the constructor you need to set the objects properties to the relevant arguments passed in the constructor. Then in the copy method since you already have a constructor that takes all the properties you need to call it with the properties of the current object.

For the equals method you compare primitive types with the == operator and strings have an equals method to check for string equality.

To write the toString method you need create a string with the relevant properties and spaces between them and return that string.

That should get you started.
