Need help with the following assignment:

Deliverables:

Pocket.java

Coin.java

Nickle.java Penny.java Dime.java Quarter.java * are all the same methods just with cooresponding names

PocketMain.Java

NoSuchCoin.java

Here is the code I have so far, it works, but I need to program to continue even after I put in an invalid type or number. I do not know where to put the exception. It is meant to have coins added to it, subtracted from it, the sum of coins added up, number of coins added up and all outputted. Here is my code:

public abstract class Coin

{

private String name;

//takes in coin name as part of constructor and stores it in a private string

public static final String DIME = "DIME";

public static final String NICKLE = "NICKLE";

public static final String PENNY = "PENNY";

public static final String QUARTER = "QUARTER";

//separate string constants for each coin

public String getName()

{

return name;

}

//method that returns coin's name

public void setName(String name)

{

this.name = name;

}

//sets the name for a coin

public Coin()

{

}

//blank class method

public Coin(String name)

{

this.name = name;

}

//coin constructor

public abstract int getValue();

//abstract getValue method

}
