In order to convert a byte array to a file, we will be using a method named the getBytes() method of String class. Implementation: Convert a String into a byte array and write it in a file. Example: Java.
Java – How to save byte[] to a filewrite is the simplest solution to save byte[] to a file. // bytes = byte[] Path path = Paths. get("/path/file"); Files. write(path, bytes);
copyOf(byte[] original, int newLength) method copies the specified array, truncating or padding with zeros (if necessary) so the copy has the specified length. For all indices that are valid in both the original array and the copy, the two arrays will contain identical values.
You can use:
File.WriteAllBytes("Foo.txt", arrBytes); // Requires System.IO
If you have an enumerable and not an array, you can use:
File.WriteAllBytes("Foo.txt", arrBytes.ToArray()); // Requires System.Linq
You can use File.WriteAllBytes
