I am trying to make a class that flips a coin and returns the year and type of coin and if its head or tails. I am sure that i made my class correctly but can someone show me how the tester class should look like.

This is my class:

public class Coin

//These are constants that are provided for your use. For example, using the 
constant "TAILS" is the same as typing a 1.
private final static int HEADS = 0;
private final static int TAILS = 1;
private final static int UNKNOWN = -1;

//ADD: private instance variables, type (String), year (int), face (int)
private String type;
private int year;
private int face;

// ADD: set type and year to parameters, set face equal to UNKNOWN
public Coin(String _type, int _year)

type = _type;
year = _year;
face = UNKNOWN;


//ADD: set type, year and face to parameters
public Coin(String _type, int _year, int _face)

type = _type;
year = _year;
face = _face;


// ADD: return the value of variable type
public String getType()

 return type;


// ADD: if the year is between 1850 and 2015 (inclusive) set the year and retrn true.
// Otherwise, just return false
public boolean setYear(int _year)

year = _year;
if ((year >= 1850) && (year <= 2015)) 

 return true;
 
else

 return false;



// ADD: return the value of the coin. (.25 for a quarter, .10 for a dime, etc.)
// Precondition: type will have a valid value of "quarter", "dime", "nickel" or "penny"
public double getValue()

 double value;
 if (type == "quarter")
 
 value = .25;
 

 if (type == "dime")
 
 value = .10;
 

 if (type == "nickel")
 
 value = .05;
 

 if (type == "penny")
 
 value = .01;
 
 return value;


// ADD: return the year
public int getYear()

return year;


// ADD: return the string "heads", "tails" or "unknown"
public String getFace()

 return face;


//ADD: Use Math.random to produce a random int (0 for heads, 1 for tails). 
//Set face equal to the value and then use the getFace method to return "heads" or "tails"
//To call the getFace method, the code is simply: getFace()
public String flip()

if (Math.random() < 0.5)

getFace("Heads");

else

 getFace("Tails");

return flip;



// ADD: return the year and type of coin. For example: 1985 quarter
public String toString()

This is my Tester Class:

/* Prompt the user for the number of coin flips.
Flip the count the designated number of times - displaying the number of the coin 
flip and the result
Display the number of coin heads and number of tails!

How many flips would you like? 4
1. heads
2. tails
3. heads
4. heads

The results:
3 heads - 75.0%
1 tails - 25.0%

import java.util.Scanner;
public class CoinFlipper

public static void main(String[] args)

 Coin coin = new Coin("quarter",1950,0);
Scanner in = new Scanner(System.in);
int flips;
System.out.println("How many flips?");
flips = in.nextInt();

System.out.println("The results:");
