Why Java is used so much to create applications how it is different from other languages?

It is simple and easy to write the language. And the best thing about Java is that it is machine independent and can be written once and run anywhere. Furthermore, Java is a statically typed programming language that makes it faster than other languages. Java considers security as part of its design.

Why is the import statement needed?

In Java, the import statement is used to bring certain classes or the entire packages, into visibility. As soon as imported, a class can be referred to directly by using only its name. The import statement is a convenience to the programmer and is not technically needed to write complete Java program.

What is the advantage of using import statements?

The import statement is to tell the compiler where to find the classes that the source code is referring to. However, there is an advantage to importing only by classes. If there is a class with the exact same name in two packages, there is going to be a conflict as to which class is being referred to.

Why is Java preferred in the industry?

One of the biggest reasons why Java is so popular is the platform independence. Programs can run on several different types of computer; as long as the computer has a Java Runtime Environment (JRE) installed, a Java program can run on it. Java is fundamentally object-oriented.

Why Java is considered as best language for Internet applications?

Rich API: Java is considered as one of the most successful program languages due to its rich API (Application Programming Interface).
