Using the display() Method

Since this method is a member of a CheckingAccount object, the object's data is accessed by using the variable name, like accountNumber. The dot operator is needed outside of the object, like account1.accountNumber in the main method.

Another nice thing to do is to use the tabulation character "\t" to align the output better. When the display() has been defined, the testing program can be more easily written:

class CheckingAccount
{
  . . . . (Now including the display() method.)
}

class CheckingAccountTester
{
  public static void main( String[] args )
  {
    CheckingAccount account1 = new CheckingAccount( "123", "Bob", 100 );

    account1.display() ;
    account1.processDeposit( 2000 );
    account1.processCheck( 1500 );
    account1.display() ;

  }
}
