icalculator's Introduction

iCalculator

A calculator by myself in Java

目的

学习表达式求值后,根据自己的理解,运用Java编写了该计算器。计算器可完成小数,多位数,带符号数,三角函数和带括号表达式的加、减、乘、除、乘方、开方等复杂的计算。

队列中的符号替代:

sin:-1.01101  
cos:-1.01102  
tan:-1.01103  
sqrt:-1.01104  
加号:-1.01001  
减号:-1.01002  
乘号:-1.01003  
除号:-1.01004  
乘方:-1.01005  
左括号:-1.01006  
右括号:-1.01007  

原理

  • 使用队列和栈进行表达式求值,具体实现可参考这篇博客,两者的核心思路是一致的

  • 运用Java的Swing包完成控件的布局
