Question

I have DirectoryPath:
data/data/in.com.jotSmart/app_custom/folderName/FileName
which is stored as a String in ArrayList

Like

ArrayList<String> a;
a.add("data/data/in.com.jotSmart/app_custom/page01/Note01.png");

Now from this path I want to get page01 as a separate string and Note01 as a separate string and stored it into two string variables. I tried a lot, but I am not able to get the result. If anyone knows help me to solve this out.

Answer 1

f.getParent()

Returns the pathname string of this abstract pathname’s parent, or null if this pathname does not name a parent directory.

For example

    File f = new File("/home/jigar/Desktop/1.txt");

    System.out.println(f.getParent());// /home/jigar/Desktop
    System.out.println(f.getName());  //1.txt

Update: (based on update in question)

if data/data/in.com.jotSmart/app_custom/page01/Note01.png is valid representation of file in your file system then

for(String fileNameStr: filesList){
  File file = new File(fileNameStr);
  String dir = file.getParent().substring(file.getParent().lastIndexOf(File.separator) + 1);//page01
  String fileName = f.getName();
  if(fileName.indexOf(".")!=-1){
     fileName = fileName.substring(0,fileName.lastIndexOf("."));
   }
}
