下面是一个代码块,它做了两件事 - 函数 readBCInputDataFromTextFile 读取文本文件,并将读取的数据存储在变量 textData 中,该变量是一个字符串数组(即 String[]) 数组大小使用 int 变量填充numOfLines(同样在函数 readBCInputDataFromTextFile 中)。此功能完美运行。
代码所做的第二件事(在函数 checkBCInput 中) - 现在不起作用 - 是使用正则表达式分离数据并将其存储在 4 个“容器”(所有这些都是向量)中:bcStringConstant、bcNameVec、bcTempVec 和bcHTCVec。
现在我的问题是:如何将变量 textData 传递给函数 checkBCInput。如果我将这两个函数的代码合并到一个 java 文件中,代码就可以执行。但是这种让事情发挥作用的方式并不是很好——模块化会受到影响。因此,我需要将代码分成两个函数——一个读取文本文件并将读取的内容传递给第二个函数,第二个函数使用正则表达式将读取的数据存储到特定的容器中。
我尝试从 readBCInputDataFromTextFile 返回 textData,但这在我正在运行的当前模拟中不起作用。我还尝试将读取的数据传递给 checkBCInput——但这会导致另一个错误消息:“找不到符号:符号 textData”。第二种方法(下面以粗体显示)将起作用,但我还看不到解决方案:-/
