Hi Malvika,

There is no direct answer to your questions.

I am learning java since last 15 years and still learning.

But yes, to know the basics of Java where you can start programming and understanding the things in a different way, it takes max 2 months, in which yo can learn the basics in depth Java programming knowledge and after this such knowledge, no programming laguage gets difficult for you.

I am working in TCS for last 9 years in Java technology and evryday I learn something new.

To start with I suggest you start with the base, as if the base is strong nothing will stop you.

Rest all the frameworks and technologies which are coming day on day are all based on the basics.

Learn the core java hard and thn shift to Server side technologies.

I prefer you to learn from a Book/Teaching instaed of online. Download a E book and start learning.

Every where in Java only, Android is Java, IOs is java, New Blockchain tech is also java.

from Coffe machine to Super computer all is Java, so learn and earn as much as you can :) Good luck.

There are n number of websites that have free content on Java (w3 school, GeeksforGeeks and Javatpoint being a few common ones).in w3 school you are havng try it button so that you van try in that editor only

You can start with the basics and later you will be able to proceed to other advanced features 

1. Java is a platform independent language, that means it can be coded at one computer and executed in another, it is also easily portable.
2. It is used in web development because of various libraries available for adaption to latest technology and it can be used for creation of user friendly web services.
3. It is high level and object oriented programming language with high security. Hence it is used for application developments.    

No I don't think so

Although you should keep in mind that Java is not the only choice for web applications, many developers choose Java over other languages because they consider Java to be the best programming language for use in web development. After all, Java is well-established, flexible, and powerful.

Here is a step-by-step approach to learn Java from Core Java to Advanced Java in the shortest possible time - a journey from novice to expert.

Although the question has specifically asked for a single website, yet I’ll go for a mix-and-match approach, as I believe this is the best way to make a journey from novice to expert in Java and also to prepare for Job Interviews

1. Step 1 - Core Java - Buy a Java certification book (even if you do not have any plan to do certification) because over the years I have seen that the certification books are extremely helpful to learn the subject. Read the book cover to cover and you will be quite comfortable with the important concepts of Core Java. Buy the book after checking the review in Amazon.
2. Step 2 - Java New Features - Starting from Java 5 through to Java9, search in the Google for the top 10 new features introduced in each version. Do further research in the internet to learn about each new feature
3. Step 3 - GoF Design Patterns - This StackOverflow answer is (my personal opinion) the best set of examples of the GoF Design Pattern Examples of GoF Design Patterns in Java's core libraries. This answer tells you which Java libraries implement which design patterns. Keep this as a reference and reserach in the internet for each of these design patterns until you understand most of the design patterns
4. Step 4 - Enter Spring Framework - Learn about dependency Injection (DI) and Inversion of Control (IoC) patterns and also how to use these patterns using core Spring or Spring DI. Also learn about Spring JDBC
5. Step 5 - Enter JEE - This StackOverflow answer A summary of all Java EE specifications will give you an idea about what JEE is and a brief overview of each specification. Just know what they are used for. Focus and learn in detail the following:
1. Servlet
2. Web Socket
3. Concurrency Utilities
4. JAX-RS
5. JAX-WS
6. JAXP
7. JAXB
8. JMS
9. JPA
6. Step 6 - JEE new features - Starting from JEE 5 through to JEE 8, search in the Google for the top 10 new features introduced in each version. Do further research in the internet to learn about each new feature
7. Step 7 - Enter Web Development - Learn developing an web application using any one of the following
1. Spring MVC
2. Struts 2
3. JSF
8. Step 8 - Start Open Source Journey - Some of the important open source projects worth learning
1. Log4j 2
2. Maven
3. Tomcat JDBC Connection Pool
9. Step 9 - Beginning of the Journey -
1. Deep dive into all of the above
2. Learn about new open source projects
3. Develop a complete web application e2e for practice

After all these steps, stop remaining solely focused in Java. Look around. Learn about new technologies. The ultimate goal is to provide performing, cost-effective, scaleable software solutions by mix-and-match of right technologies.
