Everything in Java seems to follow capitalization rules except for Hashtable. 

Hashtable&lt;String, String&gt; ht = new Hashtable&lt;String, String&gt;();


as opposed to 

ArrayList&lt;String&gt; a = new ArrayList&lt;String&gt;();


or 

HashMap&lt;String,Integer&gt; a = new HashMap&lt;String,Integer&gt;(); 


Why is this ? Is Hash Table read as just one word (Hashtable) ?


Question: How to modify source port in mount application linux
Answer: Assuming this is an NFS mount you are talking about you can set the ports using the guidelines in the following document:

https://access.redhat.com/site/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Storage_Administration_Guide/s2-nfs-nfs-firewall-config.html

Admittedly, this is for Red Hat but should be easily adaptable for other variants.
