Question

Java programming.

Write a public Java class called WriteToFile that opens a file called words.dat which is empty. Your program should read a String array called words and write each word onto a new line in the file. Your method should include an appropriate throws clause and should be defined within a class called TextFileEditor.

The string should contain the following words:
{“the”, “quick”, “brown”, “fox”}

Answer 1

import java.io.FileWriter;
import java.io.PrintWriter;

public class WriteFile {
        public static void main(String[] args) throws Exception {
                String arr[] = { "the", "quick", "brown", "fox" };
                writeFunction(arr);

        }

        private static void writeFunction(String[] arr) throws Exception {
                PrintWriter pw = new PrintWriter(new FileWriter("words.dat"));
                for (String s : arr) {
                        pw.println(s);
                }
                pw.close();
        }
}
