java中如何将字符串组合为一个“文件路径”呢？

实现思路:
    方式1:可借助java.nio.file.Path 中的Paths类中的方法生成路径
    方式2:可借助File对象生成相应的路径信息

//方式1 Java8
Path path = Paths.get(path1,path2,"文件名.txt");

//方式2 
File baseDirectory = new File(path1);
File subDirectory = new File(baseDirectory,path2);
File fileInDirectory = new File(subDirectory,"文件名.txt");
