how to make a computer program using java

In this article we’re going to take a look at the top differences between Java and C++. This dissimilarity will play a huge role in your future project.

Java is an interpreted language, while C++ is a compiled language. Most C++ programmers will tell you that converting to a Java project is easy for them since style and syntax are very similar.Įven with the similarities, however, the two languages are worlds apart. They both have similar syntax, support object-oriented programming (OOP), and they both power some of the biggest enterprise platforms on the market. You’ve probably done a little research into the right language, but it’s difficult for someone without software development expertise to determine which one is right.īoth Java and C++ have been in production for years. Which language is right for your software project? In the other corner you have the Java programming language-developed by Sun Microsystems with the mantra: “write once, run anywhere.” We will discuss the internal working of () statement in the coming section.In one corner, you have C++ -a C language with classes developed by Bjarne Stroustrup in 1985 that's great for writing systems-level code. Here, System is a class, out is an object of the PrintStream class, println() is a method of the PrintStream class.

String args or String args is used for command line argument.

main represents the starting point of the program.

void is the return type of the method.The main() method is executed by the JVM, so it doesn't require creating an object to invoke the main() method. The core advantage of the static method is that there is no need to create an object to invoke the static method. If we declare any method as static, it is known as the static method.

public keyword is an access modifier that represents visibility.class keyword is used to declare a class in Java.Let's see what is the meaning of class, public, static, void, main, String, ().

When we compile Java program using javac tool, the Java compiler converts the source code into byte code.
