Java implementation of address book management system tutorial

The example in this article shares the specific code for implementing the address book management system in Java for your reference. The specific content is as follows

Process of completing the project:

1. Determine the general direction according to the needs
2. Function module analysis
3. Interface implementation
4. Function module design
5.coding
6. Code test

The following is the source code:
