I need to create an Account.jav and Account test.java but I am lost PLZHelp

Question

This is what I got I have tried understanding what I am doing wrong I am really lost and I am begging anyone to help me PLEASE?!?
// Fig. 3.12: AccountTest.java
// Create and manipulate an Account object.
public class Account
     private double balance; // instance variable that stores the balance
   // constructor
     public Account( double initialBalance )
      // validate that initialBalance is greater than 0.0;
      // if it is not, balance is initialized to the default value 0.0
          if ( initialBalance > 0.0 )
        balance = initialBalance;
   } // end Account constructor
   // debit (subtract) an amount to the account
     public void debit( double amount )
          balance = balance - amount; // add amount to balance
    // end method debit
if(debitAmount>account1.getBalance())
     System.out.printf("You don't have enough money for this transaction, the amount available is  $%.2f",getBalance());
else
     account1.debit(debitAmount);
     System.out.printf("The new balance is $%.2f",getBalance());
//And for AccountTest.java:
public class AccountTest {
     // main method begins execution of Java application
public static void main( String args[] )
     Account account1 = new Account( 50.00 ); // create Account object
     double currentBalance = account1.getBalance();
// display initial balance of each object
     System.out.printf( "account1 balance: $%.2f\n",
     currentBalance );
// create Scanner to obtain input from command window
     Scanner input = new Scanner( System.in );
     double debitAmount; // debit amount read from user
          System.out.print( "Enter withdrawl amount from your account: " ); // prompt
          debitAmount = input.nextDouble(); // obtain user input
          if(debitAmount > currentBalance)
               System.out.printf("Debit amount of $%.2f is greater than the Available Balance of $%.2f.%n",debitAmount,currentBalance);
          else
               System.out.printf( "\nwithdrawling %.2f to account1 balance\n\n", debitAmount );
               account1.debit( debitAmount ); // add to account1 balance
               currentBalance = account1.getBalance();
// display balances
     System.out.printf( "account1 balance: $%.2f\n",     currentBalance );
     } // end main
}

Did you have a specific question?
There are several thing I would like to point out
1. Did you keep both the public classes in the same file(AccountTest.java)? Each java file can contain only one public class. Either move class Account to its own file (Account.java) or remove the public modifier (i.e., make it friend)
2. Class Account is not defined properly. What is that hanging if statement doing there?
3. There is a call to method getBalance() of the Account class. Where have you defined it?
Here's the modified source.
File 1. Account.java. Notice the method getBalance which was previously missing.
// Separate file Account.java
// Create and manipulate an Account object.
public class Account
  private double balance; // instance variable that stores the balance
  // constructor
  public Account( double initialBalance )
    // validate that initialBalance is greater than 0.0;
    // if it is not, balance is initialized to the default value 0.0
    if ( initialBalance > 0.0 )
      balance = initialBalance;
  } // end Account constructor
  // debit (subtract) an amount to the account
  public void debit( double amount )
    balance = balance - amount; // add amount to balance
  }// end method debit
  public double getBalance()
    return this.balance;
}File 2. AccountTest.java.
//AccountTest.java
import java.util.Scanner;
public class AccountTest
  // main method begins execution of Java application
  public static void main( String args[] )
    Account account1 = new Account( 50.00 ); // create Account object
    double currentBalance = account1.getBalance();
    // display initial balance of each object
    System.out.printf( "account1 balance: $%.2f\n", currentBalance );
    // create Scanner to obtain input from command window
    Scanner input = new Scanner( System.in );
    double debitAmount; // debit amount read from user
    System.out.print( "Enter withdrawl amount from your account: " ); // prompt
    debitAmount = input.nextDouble(); // obtain user input
    if(debitAmount > currentBalance)
      System.out.printf("Debit amount of $%.2f is greater than the Available Balance of $%.2f.%n",debitAmount,currentBalance);
    else
      System.out.printf( "\nwithdrawling %.2f to account1 balance\n\n", debitAmount );
      account1.debit( debitAmount ); // add to account1 balance
      currentBalance = account1.getBalance();
    // display balances
    System.out.printf( "account1 balance: $%.2f\n",  currentBalance );
  } // end main
}Are your questions answered? Have you learnt something out of all this?
