  a1.cunkuan ();
  a1.qukuan ();
  a1.chaxun ();
  a1.finalize ();
  
 }
}

The results are as follows:

Experimental experience:

1.Java in object-oriented class encapsulating core features, is thought specific implementation information hiding technology, and the feeling in C ++ classes encapsulated many similarities.

2. The procedure to get a start, no start, after careful thought, nothing more than the private banking clients of information hiding, then there are operations on the money, and take on deposit.

3. This program should also take into account the money deposited is greater than zero, the money in the account is greater than the money taken.
