Extention for prior Java 8 solution

<pre><code>String result = String.join(",", name);
</code></pre>

If you need prefix or/ and suffix for array values

<pre><code> StringJoiner joiner = new StringJoiner(",");
 for (CharSequence cs: name) {
 joiner.add("'" + cs + "'");
 }
 return joiner.toString();
</code></pre>

Or simple method concept

<pre><code> public static String genInValues(String delimiter, String prefix, String suffix, String[] name) {
 StringJoiner joiner = new StringJoiner(delimiter);
 for (CharSequence cs: name) {
 joiner.add(prefix + cs + suffix);
 }
 return joiner.toString();
 }
</code></pre>

For example 

<pre><code>For Oracle i need "id in (1,2,3,4,5)" 
then use genInValues(",", "", "", name);
</code></pre>

<pre><code>But for Postgres i need "id in (values (1),(2),(3),(4),(5))"
then use genInValues(",", "(", ")", name);
