I need to write a class that encapsulates this program It sh

I need to write a class that encapsulates this program. It should supplement the constructor, accessors, and mutators. As well as methods like toString and equals.The program should not be altered.

Quarters, dimes, nickles, and pennies all need methods.

import java.text.NumberFormat;

public class CoinsClient
{
public static void main( String [] args )
{
    NumberFormat dollarFormat = NumberFormat.getCurrencyInstance( );

    Coins c1 = new Coins( 4, 3, 2, 3 );
    Coins c2 = new Coins( -1, 5, 3, 4 );
    System.out.println( \"The number of quarters of coins #1 is \" + c1.getQuarters( ) );
    System.out.println( \"The number of dimes of coins #1 is \" + c1.getDimes( ) );
    System.out.println( \"The number of nickels of coins #1 is \" + c1.getNickels( ) );
    System.out.println( \"The number of pennies of coins #1 is \" + c1.getPennies( ) );

    System.out.println( \"\ Coins #2 is \" + c2.toString( ) );
    System.out.println( \"From quarters: \" + dollarFormat.format( c2.moneyFromQuarters( ) ) );
    System.out.println( \"From dimes: \" + dollarFormat.format( c2.moneyFromDimes( ) ) );
    System.out.println( \"From nickels: \" + dollarFormat.format( c2.moneyFromNickels( ) ) );
    System.out.println( \"From pennies: \" + dollarFormat.format( c2.moneyFromPennies( ) ) );
    c2.outputTotalAmount( );
    System.out.println( );

    if ( c1.equals( c2 ) )
      System.out.println( \"Original coins #1 and #2 are identical\" );
    else
      System.out.println( \"Original coins #1 and #2 are different\" );

    c2.setQuarters( 4 );
    c2.setDimes( 3 );
    c2.setNickels( 2 );
    c2.setPennies( 3 );

    if ( c1.equals( c2 ) )
      System.out.println( \"Original coins #1 and modified coins #2 are identical\" );
    else
      System.out.println( \"Original coins #1 and modified coins #2 are different\" );

}
}

// Created Coin Class to include all the deifined functionalities
import java.text.NumberFormat;
public class Coins

}

}
void outputTotalAmount()
{
double amount = quarters*25 + dimes*10 + nickels*5 + pennies;
System.out.println( \"Total amount is \" + amount);
