Replace old path to new path

I have below mentioned full path string:

String originalpath = C:\test\sample\batchmatch\internal\a\b\a.pdf

I need to replace first part of the path with new path

For example:

oldpath =  C:\test\sample\batchmatch\internal\to 
new path = C:\testdemo\sampledemo\batchmatchdemo\internal

I have tried below mentioned approach, but it doesn't work.

String newpath = originalpath.replaceAll(oldpath,newpath);

Could you please help me?

class Demo {
    public static void main(String[] args) {
        String originalpath = C:\test\sample\batchmatch\internal\a\b\a.pdf;
        String oldpath =  C:\test\sample\batchmatch\internal\;
        String newpath = C:\testdemo\sampledemo\batchmatchdemo\internal;
        String relacepath = a.replaceAll(oldpath ,newpath);
        System.out.println("replacepath::"+ relacepath );
    }
}

There are several methods to do this as for example :

    String communPath = "C:/test/sample/batchmatch/internal";
    String secondpartOfPath = "/a/b/a.pdf";
    String originalpath = communPath.concat(secondpartOfPath);
    String newPath = "C:/testdemo/sampledemo/batchmatchdemo/internal";
    System.out.println(originalpath);
    String path = originalpath.replaceAll(communPath, newPath);
    System.out.println(path );

originalpath : C:/test/sample/batchmatch/internal/a/b/a.pdf

path : C:/testdemo/sampledemo/batchmatchdemo/internal/a/b/a.pdf

This should be a bit flexible for you irrespective of your platform (i.e \ or /)

    String oldPath =  "C:\\test\\sample\\batchmatch\\internal\\a\\b\\a.pdf".replaceAll("(\\\\+|/+)", "/");
    String newPath = "C:\\testdemo\\sampledemo\\batchmatchdemo\\internal".replaceAll("(\\\\+|/+)", "/");

    String partToKeep = "\\a\\b\\a.pdf".replaceAll("(\\\\+|/+)", "/");
    String partToReplace = oldPath.substring(0, oldPath.indexOf(partToKeep));

    String replacedPath = oldPath.replaceAll(partToReplace, newPath).replaceAll("(\\\\+|/+)", Matcher.quoteReplacement(System.getProperty("file.separator")));
    System.out.println(replacedPath);

    String originalpath = "C:/test/sample/batchmatch/internal/a/b/a.pdf";
    String oldpath =  "C:/test/sample/batchmatch/internal";
    String path = "C:/testdemo/sampledemo/batchmatchdemo/internal";
    System.out.println(originalpath);
    String newpath = originalpath.replaceAll(oldpath,path);

    System.out.println(newpath);

  }
