Java Programming Language | Beginner to Advance level

Java is a powerful programming language for general purposes. It is used to develop mobile and desktop applications, Web servers, and application servers, Games, Database connections, large-scale data processing, embedded systems, etc. Java is one of the most popular languages for programming.

java language
  • Java was one of the most popular programming languages.Java is an object-oriented programming language.
  • It is not considered pure object-oriented, however, because it supports primitive data types (like int, char, etc)
  • The Java code is compiled into byte code first (machine-independent code). Then, regardless of the underlying architecture, the byte code runs on the Java Virtual Machine (JVM).
  • The syntax of Java is similar to that of C/C++. However, Java does not include low-level programming features such as pointers. In addition, Java programs are always written as classes and objects.
  • When compared to C++, Java code is generally easier to maintain because Java does not allow many things that, if used incorrectly, could lead to bad/inefficient programming. Non-primitives, for example, are always references in Java. As a result, we can’t pass large objects to functions like we can in C++; instead, we must pass references in Java. Another example is that because there are no pointers, bad memory access is impossible.
  • Java is a cross between C++ and Python when compared to Python. Java programmes are typically faster than Python counterparts, but slower than C++ programmes. Java, like C++, performs static type checking; however, Python does not.

Hello World Example:

class Example{  
    public static void main(String args[]){  
     System.out.println(“Hello Java”);  
    }  
}
