Java Exception try-with-resources for two resources

Introduction

We can put more than one resource within a single try statement.

import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;

public class Main {
  public static void main(String args[]) throws IOException {
    int i;//ww  w . j av  a  2s.c o  m

    // Open and manage two files via the try statement.
    try (FileInputStream fin = new FileInputStream("Main.java");
        FileOutputStream fout = new FileOutputStream("Test.java")) {

      do {
        i = fin.read();
        if (i != -1)
          fout.write(i);
      } while (i != -1);

    } catch (IOException e) {
      System.out.println("I/O Error: " + e);
    }
  }
}
import java.io.BufferedOutputStream;
import java.io.DataOutputStream;
import java.io.FileOutputStream;

public class Main {
   public static void main(String[] args) {

      try (FileOutputStream fos = new FileOutputStream("out.log");
            BufferedOutputStream bos = new BufferedOutputStream(fos);
            DataOutputStream dos = new DataOutputStream(bos)) {
         dos.writeUTF("This is being written");
         // let's throw an exception and

         dos.close();/*from w  w w  .j  a v a 2 s .  c o  m*/
      } catch (Exception e) {
         System.out.println("Some bad exception happened ");
      }
   }
}
