What is a factorial number in Java?

Java Programming Java8Java Technologies. Factorial of a positive integer n is the product of all values from n to 1. For example, the factorial of 3 is (3 * 2 * 1 = 6).

How do you find Factorials?

To find the factorial of a number, multiply the number with the factorial value of the previous number. For example, to know the value of 6! multiply 120 (the factorial of 5) by 6, and get 720.

What are interfaces for in Java?

In Java, an interface is an abstract type that contains a collection of methods and constant variables. It is one of the core concepts in Java and is used to achieve abstraction, polymorphism and multiple inheritances. We can implement an interface in a Java class by using the implements keyword.

Why Java is called a platform independent language?

When the Java program runs in a particular machine it is sent to java compiler, which converts this code into intermediate code called bytecode. … JVM recognizes the platform it is on and converts the bytecodes into native machine code. Hence java is called platform independent language.
