Java Programming Language

Java Programming Language

Java Programming Language is one of the most popular and widely used programming languages.

  • For many years, Java has been regarded as one of the most widely used programming languages.
  • Object-Oriented programming is what Java is all about. However, because it supports basic data types, it is not regarded entirely object-oriented (like int, char, etc)
  • The Java programmes are converted to byte code first (machine independent code). After then, regardless of the underlying architecture, the byte code runs on the Java Virtual Machine (JVM).
  • The syntax of Java is comparable to that of C/C++. However, low-level programming features such as pointers are not available in Java. Furthermore, Java programmes are always written as classes and objects. You can also visit us on Best Job Opportunities in Cloud Computing.
  • Java is used in a wide range of applications, including mobile apps (Android is based on Java), desktop apps, and web apps.
  • Java Programming Language is used in a wide range of applications, including mobile apps (Android is Java-based), desktop apps, online apps, client-server apps, enterprise apps, and many others.
  • When compared to C++, Java codes are often more maintainable 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 send big objects to functions like we can in C++; instead, we must pass references in Java. Another example is that because there are no pointers, incorrect memory access is impossible.
  • Java is a cross between C++ and Python when compared to Python. Java programmes are often quicker than Python counterparts, but slower than C++ programmes. Java, like C++, performs static type checking; however, Python does not. You can also visit us on Top 10 Highest Paying Programming Languages For Better Future.

Simple Hello World Program :

// A Java program to print "Hello World"

publicclassGFG {     

publicstaticvoidmain(String args[])     

{         

System.out.println("Hello World");     

}

}

Output :

Hello World
