Java 将文件读取器合并到代码中时出现问题
我已经写了这段代码，几乎完成了，但是我一直想知道如何在代码中实现filereader，将文件中的数据放入现有的数字列表/数组中。我在一些网站上查阅了如何安装filereader，但在语法方面却被一次又一次地难住了：（我还被迫坚持使用Java1.4.2，所以我不能使用Scanner之类的东西 以下是不完整的代码：Java 将文件读取器合并到代码中时出现问题,java,filereader,Java,Filereader,我已经写了这段代码，几乎完成了，但是我一直想知道如何在代码中实现filereader，将文件中的数据放入现有的数字列表/数组中。我在一些网站上查阅了如何安装filereader，但在语法方面却被一次又一次地难住了：（我还被迫坚持使用Java1.4.2，所以我不能使用Scanner之类的东西 以下是不完整的代码： import java.io.BufferedReader; import java.io.FileNotFoundException; import java.io.FileReade
