通过JAVA设计 GUI 界面的计算器程序，用户可以通过鼠标依次输入参加计算的数值，进行加、减、乘、除等混合运算,这些完成标准计算器的基础操作。当选择科学计算器后，可以实现sin 、 cos 、 tan 、 ln、x^y、x^2、x^3、pi、n!、mod和十六进制除这个以外还可以删除输入，清空结果，求1除X，X百分比，十进制是，八进制，二进制的相互转换。-GUI interface design through JAVA calculator program, the user can take part in the importation of the mouse followed by the numerical calculation for add, subtract, multiply, divide, such as mixed computing, which the basis of the standard calculator operation. When choosing a scientific calculator, you can realize sin, cos, tan, ln, x ^ y, x ^ 2, x ^ 3, pi, n!, Mod and hexadecimal In addition to the outside can also delete the import, empty the results, and one in addition to X, X percentage of the metric system is octal, binary mutual conversion.
