Java Garbage Collector -
      Garbage Collector in Java working for release the memory form waste (unreachable) object.
Garbage Collector works with heap memory.
              Any Object is created in Java it goes to the heap memory. When this object is being waste or unreachable then Garbage Collector release memory from its.

Understand about  waste or unreachable object -
   
    String s  = new String(“Albert”);

    String s1 = new String (“Another”);

    s1=s;

           in this case new String (“Another”); has been waste object.
Then  Garbage collector will release the memory form this object.

     Garbage Collector called by JVM directly. You can not force for release the memory.
You can request to Garbage Collector through System.gc() method.
    For tracing the event of Garbage Collection use this command
    -verbose:gc

I am writing this article for beginners. Because, at the time of learning node js, this is very confusing where and how we need to use req.query, req.params and req.body . I am going to explain these three req method below. 1.        Req.query 2.        Req.params 3.        Req.body Req.query: When request is coming in key and value pair, for example, if your URL looks like below URL http://localhost:3000/search?name=xyz&age=16 In the above URL, you can see that request is coming in key and value pair . First key is name and value is xyz, second key is age and value is 16. In the node js programing, if you want to parse this url then use req.query.
