Learning Java does not have to be complicated. It depends on how you learn. You will, however, have to invest a lot of time and energy to master Java. Get An Admission In Best Institute For Learning Best Online Java Course In 2019 Java is, what you can do with it, and which methods are suitable for learning.
What is Java?
Java is known as an object-oriented programming language. As a Java programmer, it is essential to understand the OOP (Object Oriented Programming) principle well. You can use Java to develop programs on many platforms because it is a platform-independent programming language. Examples of platforms are Windows, Mac OS, and Linux.
In terms of syntax (Grammar of the programming language), Java looks like C ++. Java is made to be simpler than C ++. A significant advantage of Java over C ++ is that Java memory leaks occur. Java manages its memory and can automatically throw away objects that are no longer being used.
Java code is executed in a JVM (Java virtual machine). Because of this, the chance is minimal that Java code can do evil things on the computer on which it runs. You can download a JVM on many operating systems. That is why you can run Java code on different platforms.
Furthermore, it is essential to install a JRE (Java runtime environment) if you want to run Java programs. JRE has a JVM and library classes. Library classes contain code that has already been written. This means you don't have to reinvent the wheel. You can therefore easily retrieve the current time and date on 1 line of code. Behind that one line of systems are more lines of code to retrieve the current date and time, but they are already written in the library classes. Programmers make grateful use of this by invoking the law from these library classes.
If you want to develop Java programs yourself, it is necessary to download a JDK (Java development kit). The JDK also includes a JRE and JVM. Also, a JDK naturally has development tools with which you can develop Java programs.
Java and JavaScript difference
Many beginners sometimes confuse Java and JavaScript, while the total is different. Let us list the differences here:
Java is a programming language, and JavaScript is a scripting language.Java programs are run in a JVM. JavaScript is executed in a browser.Java code must be compiled. JavaScript only consists of text. With Java, you can develop computer programs, apps, and games (and even more). JavaScript is intended to make websites interactive.

Now it's time to drop the complicated technical stories and focus on what we can do with it. With this, we mean what the possibilities are for a Java programmer. As a good Java programmer, you will have nothing to complain about money. The demand for good Java programmers is very high, and you can earn a good salary.

Learn Java: What are the best learning methods?
To become a good Java programmer/developer, you will need to learn the Java programming language well. Nowadays, there are countless ways to do that on the internet. Many options are usually difficult for beginners. As a result, beginners often cannot see the forest for the trees and drop out early.
Learning Java can be easier if you also understand the basics of programming better.
