java图形化界面实现简单计算器

-.z.学号11710115**城建大学Java语言程序设计C实验报告实验5：计算器学生路江飞班级11卓越7班一、实验目的1．掌握Java图形组件和布局管理器的使用；2．掌握使用Java事件处理机制的使用；3．掌握图形界面的各种控件的使用，如：标签、文本框、按钮、复选框、列表框、窗框等。二、实验要求1．采用布局管理器进行界面的布局；2．学会对不同的事件用相应的事件处理器；3．写出实验报告。要求记录编译和执行Java程序当中的系统错误信息提材示，并给出解决办法。三、实验容1．在随堂练习的简单计算器基础上设计一个多功能计算器。包括复杂的功能：比如记忆功能，三角函数，成方，对数等等。五、实验结果文件1:packageputer;import;publicclasspuere*tendsJFrame{privateJPanelcontentPane;privateJTe*tFieldte*tField;privateJTe*tFieldte*tField_1;privateJTe*tFieldte*tField_2;privateJTe*tFieldte*tField_3;/** *Launchtheapplication. */publicstaticvoidmain(String[]args){ EventQueue.invokeLater(newRunnable(){publicvoidrun(){//运行程序时，点击按钮输入公式，当点击等于号时显示出计算结果try{ puerframe=newpuer();
