import java.util.File; public class CreateFileTest { public static String createNewFile(String filename) { try { // Create file if it does not exist boolean success = new File(filename).createNewFile(); if (success) { return " did not exist and was created successfully."; } else { return " already exists."; } } catch (IOException e) { return " could not be created."; } } public static void test(String type, String filename) { System.out.println("The following " + type + " called " + filename + createNewFile(filename) ); } public static void main(String args[]) { test("file", "output.txt"); test("file", File.seperator + "output.txt"); test("directory", "docs"); test("directory", File.seperator + "docs" + File.seperator); } }
Bash
touch output.txt touch /output.txt mkdir docs mkdir /docs
