How to Find Multiple Missing Integers in Given Array With Duplicates in Java?

I found this interesting problem here: 
https://javarevisited.blogspot.com/2014/11/how-to-find-missing-number-on-integer-array-java.html
but I think the solution is too long, see mine below:

import java.util.Arrays;
import java.util.HashSet;
import java.util.Set;
import java.util.stream.Collectors;
import java.util.stream.IntStream;

public class MissingIntegers {

    public static void main(String[] args) {
       
        Set<Integer> s1 = new HashSet<>(Arrays.asList(new Integer[]{1, 2, 3, 4, 9, 8}));
        Set<Integer> s2 = new HashSet<>(IntStream.rangeClosed(1, 10).boxed().collect(Collectors.toList()));

        s2.removeAll(s1);
        System.out.println(s2);
    }
   
}

In fact we don't need the intermediate List in the case of Set 2, we can use the toCollection method of Collectors:

Set<Integer> s2 = IntStream.rangeClosed(1, 10).boxed().collect(Collectors.toCollection(HashSet::new));

Next day I came up with another solution:

import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;
import java.util.stream.Collectors;
import java.util.stream.IntStream;

public class MissingIntegers {

    public static void main(String[] args) {
       
        List<Integer> L1 = Arrays.asList(new Integer[]{1, 2, 3, 4, 9, 2, 8});
        List<Integer> L2 = IntStream.rangeClosed(1, 10).boxed().collect(Collectors.toCollection(ArrayList::new));
       
        L2.removeAll(L1);
        System.out.println(L2);
    }
   
}

Using Apache Ant in Netbeans

The following ant code is run inside the -post-jar target in a Netbeans Java project.

<!--
    Copy the .jar file and the zipped directory dist
    to deploy folder in Z: drive
-->

<echo message="Zip and copy: ${application.title}" />
       
<!--
    A file name property for the zip file we are going to create
-->
<local name="zipfile" />
<property name="zipfile" value="${application.title}-dist.zip" />

<!-- The creation of the zip file -->
<zip destfile="${zipfile}">
     <fileset dir="${dist.dir}/" />
</zip>
       
<!-- Copying the 2 files -->
     <copy todir="Z:/deploy" overwrite="true">
         <resources>
             <file file="${dist.jar}" />
             <file file="${zipfile}" />
         </resources>
     </copy>

<delete file="${zipfile}" />
       
<!-- End of the copy -->

Style Guidelines for Local Variable Type Inference in Java

Stuart W. Marks just published a very useful guidelines for the use of  the newly introduced local variable type inference in Java 10:

var list = List.of("One", "Two", 3);

New - iLink FIX Tag Library

CME just published a resource for querying their iLink FIX tag library. See the announce below.

New - iLink FIX Tag Library

In response to customer requests, a new iLink FIX Tag Library resource is currently available in the Client Systems Wiki. This page centralizes the iLink Message Specification and includes filters for querying iLink tags by:

• Tag Number
• FIX Name
• Tag Requiredness
• Tag Format
