Statement: Ask the user to enter a whole dollar amount. Then, compute the least 
amount of bills (twenties, tens, fives, and ones) needed to generate the dollar amount.

Algorithm:

Ask the user to enter a whole dollar amount. If the amount is greater than 20, divide the amount by 20. 
If there are remainders, divide the remainder by ten. Then, divide the remainder of that amount by 5. Then if there is a remainder left, 
that is the number of one dollar bills the user will have. Finally, ask the user if they would like to enter another whole dollar amount,
 or quit the program.

Implementation.

//Money in the Bank


public class moneyinthebank{


// Instance variables
// Enter a whole dollar amount
private String dollaramount;        // Whole dollar amount
private int dollar1;                // Amount 1
private int dollar2;                // Amount 2
private int dollar3;				// Amount 3
private int remainder;              // Amount 4

public void setAmount (String nm){
	//Set an amount
	  amount = nm;
  }

public string getAmount (){
	// Get a dollar amount
	return amount
  }

  public int getTwenties(){
	  // compute number of twenties needed.
	  int twenties ;
	  if (amount >= 20) amount / 20 = twenties;
	  if (amount <= 19) twenties = 0;
	  return twenties;
  }

  public int getTens(){
	  // compute number of tens needed
	  int tens;
	  if (amount >= 20) amount / 20 = dollar1;
	  if (amount <= 19) twenties = 0;
	  if (amount >= 10) amount / 10;
	  if (amount <= 10) tens = 0;
	  return tens;
}

  public int getFives(){
	  // compute number of tens needed
	  int tens;
	  if (amount >= 20) amount / 20;
	  if (amount <= 19) twenties = 0;
	  if (amount >= 10) amount / 10 = dollar2;
	  if (amount <= 10) tens = 0;
	  if (amount >= 5) amount / 5;
	  if (amount <= 5) fives = 0;
	  returns fives;
}

  public int getOnes(){
	  // compute number of ones needed
	  int tens;
	  if (amount >= 20) amount / 20;
	  if (amount <= 19) twenties = 0;
	  if (amount >= 10) amount / 10;
	  if (amount <= 10) tens = 0;
	  if (amount >= 5) amount / 5 = dollar3;
	  if (amount <= 5) fives = 0;
	  if (amount >= 5) amount / 1 = remainder; //number of ones needed
	  return ones;
}

publis String toString(){
	//determine least number of bills needed for the whole dollar amount
	String str;
	str = "Number of bills needed:  " + "\n" +
	"Twenties: " + dollar1 + "\n" +
	"Tens:" + dollar2 + "\n" +
	"Fives:" + dollar3 + "\n" +
	"Ones: " + remainder
	return str;
}
}

Revision:
I can't really revise anything, because I don't know if my program works. I do not have JAVA on my computer, so I am praying this works.
