Description: 使用Java制作计算器的实例，适合学习的Java源码下载。运用了Java2的图形界面技术和消息响应技术。通过图形界面技术，制作了计算器的用户界面。通过消息响应技术，实现响应用户的操作的功能，最终实现人机交互。用到的JAVA知识点有：窗口布局器GridLayout的应用，对按钮消息的监听和响应。
程序及注释
首先定义具有计算功能的类Calculator。在类Calculator中定义处理加减乘除运算的函数，分别命名为opAdd (),opSubtract(),opMultiply(),opDivide()。然后实现人机交互效果，要先定义实现用户界面类CalculatorGUI。通过Panel类的setLayout()函数进行用户界面的布局。此外，要通过actionPerformed(ActionEvent event))函数来实现对按钮事件的监听，并根据不同的按钮事件进行不同的运算。最后实现用户界面类与处理运算类的融合.，所以要在用户界面类(CalculatorGUI)中定义处理运算类(Calculator)的对象，这样，就完成了计算器的功能-Making use of Java calculator examples for learning Java source code download . Use of technology Java2 graphical interface and message response technology . Graphical interface technology , making the user interface of the calculator . By message response technology, features in response to user actions , and ultimately human-computer interaction . JAVA knowledge points used are: window layout is GridLayout applications for the button to listen and respond to the message .
Procedures and Notes
First class definition Calculator with calculating functions . Defined handler arithmetic operations in the class Calculator , named as opAdd (), opSubtract (), opMultiply (), opDivide (). Then realize the effect of human-computer interaction , the user interface must first define the implementation class CalculatorGUI. ( ) Function layout of the user interface by the Panel class setLayout. In addition, to be implemented on the button event listener through actionPerformed (ActionEvent event)) Platform: |
