JAVA课程设计 本计算器可以进行简单的四则运算（加、减、乘、除）但仅限于十进制下，还可以进行（八进制，十进制，十六进制）之间的相互转换，八进制最多可以输入19位数，十进制最多可以输入18位数，十六进制最多可以输入14位数,backspace表示退格, clear表示初始化，在window下直接运行（Jsp2003.bat）即可，界面为灰白对称。

-JAVA curriculum design of the calculator can be simple arithmetic (add, subtract, multiply, divide) but only under the metric system can also be used for (octal, decimal, hexadecimal) between conversion, octal can enter up to 19-digit, decimal can enter up to 18-digit, hexadecimal can enter up to 14 digits, backspace backspace said, clear that the initialization, running in the window directly (Jsp2003.bat) can interface to gray symmetry.
