我正在开发一个项目，其中 3 个文本文件存储到一个文件夹中。我试图避免将 3 个路径硬编码到源文件中。
话虽如此，我想通过在提示符下键入来运行程序：java sourceCode folderName。
请看下面我到目前为止所取得的成就

public static void main (String[] args)throws IOException {

//two other objects

int page=0;
while (scan.hasNext()){
String readprt=scan.next();
//char[] c = s.toCharArray(); //conversion into character

int size=charArray.length ; //length of word
thesize +=size;
