So I have this program and I would want to have Java figure out the username by itself.
import java.io.*; import java.nio.file.Files; public class Demo { public static void main(String[] args) throws IOException { File file = new File("/Users/angel/Desktop"); String[] files = file.list(); for (String string : files){ for (int i = 0; i < files.length; i++) { if(String.valueOf(string).contains(".png")){ File sourceFile = new File("/Users/angel/Desktop/" + string); File destinationFile = new File("/Users/angel/Desktop/Screenshots/Screenshot" + string ); Files.move(sourceFile.toPath(), destinationFile.toPath()); string = ""; } } } } }
