JDK Installation

How to Jdk Installation 

JDK stands for Java Development Kit or sometimes it is also referred as Java Standard Edition Development Kit. JDK is a development environment to develop wide range of applications such as desktop applications, web applications or mobile applications using Java programming language.

JRE, Java Runtime Environment, is also part of JDK. JRE provides the minimum requirements for executing a java application. It consists of Java Virtual Machine(JVM) executables, core classes and some supporting files.

You can download the latest version of JDK from official website of Oracle. Here is the link.

After downloading JDK, double click on the application file and follow these steps for JDK installation.

Step 1 : click on Next.
Step 2 :There are three features: Development Tools, Source Code and Public JRE. In these, development tools is compulsory and others are optional. You can choose optional features not to install but best way is to install them also. Choose location for installing JDK. By default it is C:\Program Files (x86)\Java\jdk1.7.0_25\.  If you want, you can change the location . After selecting location click on Next.

Step 3 : If you have choosed Public JRE to install then select location for Public JRE. Default location is C:\Program Files (x86)\Java\jre7\. After selecting the location click on Next.

Public JRE is a Standalone JRE. Any java application running on your system can use this JRE. It can be uninstalled seperately from JDK. Private JRE is installed inside JDK folder (C:\Program Files (x86)\Java\jdk1.7.0_25\jre) or jdk 1.8 /jre. It is used by the tools like javac etc.
Step 4 : Click on Close.

What is string immutability?

What is string immutability? Here are a set of diagrams to illustrate Java String's  immutability . 1. Declare a string String s = "abcd" ; s stores the reference of the string object. The arrow below should be interpreted as "store reference of". 2. Assign one string variable to another string variable String s2 = s ; s2 stores the same reference value, since it is the same string object. 3. Concat string s = s. concat ( "ef" ) ; s now stores the reference of newly created string object. Summary Once a string is created in  memory (heap), it can not be changed. We should note that all methods of String do not change the string itself, but rather return a new String. If we need a string that can be modified, we will need StringBuffer or StringBuilder. Otherwise, there would be a lot of time wasted for Garbage Collection, since each time a new String is created.  Here  is an example of StringBuilder u...

Java Question ..............? Q1. What is a cookie ? Ans. A cookie is a small piece of text stored on a user's computer by the browser for a specific domain. Commonly used for authentication, storing site preferences, and server session identification. Q2. Can we reduce the visibility of the overridden method ? Q3. What are different types of inner classes ? Ans. Simple Inner Class, Local Inner Class, Anonymous Inner Class , Static Nested Inner Class. Q4. Difference between TreeMap and HashMap ? Ans. They are different the way they are stored in memory. TreeMap stores the Keys in order whereas HashMap stores the key value pairs randomly. Q5. What is the difference between List, Set and Map ? Ans. List - Members are stored in sequence in memory and can be accessed through index. Set - There is no relevance of sequence and index. Sets doesn't contain duplicates whereas multiset can have duplicates. Map - Contains Key , Value pairs. Q6. Difference between Public...
