Answer:

  public static void main( String[] args )
  {
    CheckingAccount account1 = new CheckingAccount( "123", "Bob", 100 );
    System.out.println( account1.toString() );
    account1.processDeposit( 2000 );
    account1.processCheck( 1500 );
    System.out.println( account1.toString() );
    
    CheckingAccount account2 = new CheckingAccount( "007", "James Bond", 50000 );
    System.out.println( account2.toString() );
    account2.processDeposit( 70000 );
    account2.processCheck( 10000 );
    System.out.println( account2.toString() );
    
     
   }

Further Testing

When the program is run, you will see:

C:\CAI\Notes\chap32>java CheckingAccountTester
Account: 123;   Owner: Bob;     Balance: 100
Account: 123;   Owner: Bob;     Balance: 585
Account: 007;   Owner: James Bond;      Balance: 50000
Account: 007;   Owner: James Bond;      Balance: 110000

QUESTION 20:

Now try to do something a little bit tricky. Say that James wrote out a $300 check to Bob, and that Bob deposited the check in Bob's account. Add statements (after all the others in the main method) that do this.
