Delete Files with same Prefix String using Java

Question

I have around 500 text files inside a directory with a same prefix in their filename say dailyReport_.

The latter part of the file is the date of the fi

Answer 1

I know I'm late to the party. However, for future reference, I wanted to contribute a java 8 stream solution that doesn't involve a loop.

It may not be pretty. I welcome suggestions to make it look better. However, it does the job:

Files.list(deleteDirectory).filter(p -> p.toString().contains("dailyReport_08")).forEach((p) -> {
    try {
        Files.deleteIfExists(p);
    } catch (Exception e) {
        e.printStackTrace();
    }
});

Alternatively, you can use Files.walk which will traverse the directory depth-first. That is, if the files are buried in different directories.
