Steps to download and install JDK

As on when we started learning of any new technology, we should know what are the prerequisites to learn that technology. Like from where we can download the required software? and how to install it? Follow reading this article to understand, from where we can download Java JDK software and how to install it in Windows environment?

Java has two different layers like JDK and JRE. JDK stands for Java Development Kit and JRE stands for Java Runtime Environment. We need to install JDK for Java development and JRE for
executing compiled Java classes. JRE is majorly used in Production environments.

Now, you might have the question from where I can download the JDK software? To download the latest version of JDK click here, to download JDK 8 version click here, to download older version click here.

We need to accept the license to download the JDK by clicking on Radio button as shown in the below screen, Then click on OS specific link to start download process.
            
Note: x86 refers to the 32 bit OS and x64 refers to the 64 bit OS.

How to install JDK/JRE?
Installation of JDK/JRE is very easy to do in Windows environment. Follow the below steps to complete the installation process.

Step 1:
After completing the download, double click on executable file to start the installation process. Windows will point a popup saying that you need to install this software or not? click on Yes button to proceed further installation.

Step 2:
You will be show the below installation welcome screen, click on Next button to continue.
                

Step 3:
You will get the below Custom Setup form, to install which which part of JDK like Development Tools, Source code and Public JRE. By default selected as Development Tools and don't change. Also, you can change the JDK installation path by clicking on Change button. If you don't want to change and need to move on further installation, click on Next button.
             

 Step 4:
After that you will get the below installation progress screen. It will take a while to complete the process, please wait until completing.
              

 Step 5:
After completing the JDK installation, it will show you the below screen of JRE installation. If you want to Change the installation path, you can change by clicking on Change button. Otherwise click on Next button to move further installation.
              
Note: You might get a question of I am installing only JDK why JRE is coming? because when you install JRE, JRE only will install. When you installing JDK, JRE also installed. JDK has it's own JRE.

Step 6:
You can see the below JRE installation progress screen along with in how many machines are running JDK. It will take a while, please wait until it completes.
              

Step 7:
You will see the below screen with the message of Successfully installed JDK. Click on Close button.
            

After installation you need to setup the JDK path in environment variables. You can follow this article to know how to set Java path in windows.

Multithreading in java with example

Multithreading  is one of the most important concept in core java. In this article we will learn what is multithreading? , what is the use of it? and What is the use of Synchronization and when to use it?  with detailed examples. At a time, two or more threads are accessing the same object is called as Multithreading  in Java .  First, we will create two threads for two objects. It is also possible to run two or more threads on a single class object. In this case, there is a possibility to get unreliable results. If the two threads are perform same task, then they need same object to be executed each time. For your better understanding, take an example of any reservations like, railway, movie ticket booking,etc. Let us think only one berth is available in a train and two passengers are asking for that berth. The first person has sent a request to allocate that ticket/berth to him. At the same time, the second person also sent a request to allocate that ...

Prime, Fibonacci and Factorial number with example in java

Prime number, Fibonacci series and Factorial number programs are most commonly asked questions in interview. Read this article to know what is and how to write programs for prime number, fibonacci series and factorial number. Prime Number: prime number is natural number greater than 1 that has no positive divisor other than 1 and itself. A natural number greater than 1 is not a prime number, is called Composite number . For example, 7 is a prime number. Because it can divide with 1 and 7 only. Where as 8 is composite number. Since it has the divisor 2 and 4 in addition to the 1 and 8. The below example represents the finding the passing number is prime number or not. If the passing number is prime number it will print true otherwise it will print false. package com . javatbrains . practice ; public class PrimeNumber { public boolean isPrimeNumber ( int number ) { if ( number <= 1 ) return false ; // There's only one ...

How to sort list of objects in java with examples

We could achieve list of objects sorting in java by using sort() method which is available under Collections class as well as by using Comparable and Comparator  interfaces. Comparable and Comparator are two interfaces in java used to sort list of objects. These interfaces are available under java.util package along with Collections  class and other classes and interfaces. Comparable interface contains the method of       public int compareTo(Object obj) Comparator interface contains the method of       public int compare(Object obj1, Object obj2) The compare() and compareTo() methods will return negative integer(-1), or zero(0) or positive integer(1). When the first obj1 is less than obj2 method will return negative integer. When obj1 is equals to obj2 will return zero and when obj1 is grater than obj2 it will return positive integer. If it's objects are stored in any Collection classes like ArrayList, H...

A: String is a class in java.lang package. But, in java, all classes are also are considered as data types. So we can take String as data type also. Q2:  What is the difference between == and equals() methods in java? A: == operator compares the references of the String object. It does not compare the content of the object. equals() method compares the contents. While comparing the Strings, equals method should be used as it yields the correct result. Q3:  What is String constant pool? A: String constant pool is a separate block of memory where the String objects are held by JVM....

Store file into table by using JDBC with example

To store large data files or text files into database table, we will use CLOB (Charecter Large Object) datatype of SQL . By using CLOB it is possible to save entire text book or a file or resume into a column of data table. If your using MySQL database instead of CLOB use LONGTEXT to save file into datatable. For saving files into a data table, we need to create one table which will contains a column type as CLOB to store files. Here, is the query to create a data table. 1 2 3 4 create table myfiles( file_id int ( 10 ), file_name varchar ( 30 ), file_type LONGTEXT); Once table creation completes, these table contains the 3 columns one is file_id represents the file id, file_name represents the name of the file and finally file_type will get save entire file into the table column. Now, we will move to write a JDBC program which will saves the file into the newly creating table. Here is the JDBC program, 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16...
