I have an array of String
file names and I want to convert them into File
array. I am wandering whether there is a more elegant way of doing it rather than this one.
String[] names = {file1, file2, file3};
File[] files = new String[names.length];
for (int i = 0; i < names.length; i++) {
files[i] = new File(names[i]);
}
EDIT Thanks for noting in comments. I am using Java 8
In Java 7 or less, using plain JDK, there's not. Since Java 8, you may use streams for this:
String[] names = {file1, file2, file3};
File[] files = Arrays.stream(names)
.map(s -> new File(s))
.toArray(size -> new File[names.length]);
