JDK Vs JRE

JDK = JRE + Java Development tools
JRE = JVM + Java inbuilt packages + Run time libraries

So make sure you always point JDK JRE in your project build path.

Except the above difference rest of the things are same with Standard JRE's and JRE inside JDK.

String pool is subset of Heap memory (Where objects will be created). e.g. String companyName = "Surimenus";      String empName= "Bhargav";       Using 'New' Operator If a String is created using new operator, memory will be allocated in Heap Memory not in String pool. e.g. String companyName = new String("Surimenus"); String empName= new String("Bhargav"); String Pool vs Using 'new' Operator String which are created in String pool will re-reference by reference which contains the same content. For example consider the following. String cn1 = "Surimenu"; String cn2 = "Surimenu"; In the above scenario cn1 and cn2 references having the same content and these are created in Strin...
