while loop to calculate fibonacci series upto n numbers Let’s write a Java program to calculate the Fibonacci series.
It is a series in which the next term is the sum of the preceding two terms. Write a Java program to calculate Fibonacci Series up to n numbers. On executing the above program, you will get factorial of a number as shown below: Enter the number:įactorial of entered number is: 47900160 3. ("Factorial of entered number is: "+factorial) Scanner scanner = new Scanner(System.in) Scanner object for capturing the user input Now, let’s write a program and find factorial of a number using recursion. The factorial of a number n is denoted by n! Write a Java program to calculate a Factorial of a number.įactorial of a number is the product of all the positive numbers less than or equal to the number. When you execute the above program, the output looks like as shown below: Enter two numbers: 20 98Ģ0.0 / 98.0 = 0.2 2. operator doesn't match any case constant (+, -, *, /) nextDouble() reads the next double from the keyboard Let’s implement the basic calculator operations with the help of the below program. When you think about a calculator, operations like addition, subtraction, multiplication, and division comes into the mind. Write a Java program to perform basic Calculator operations. Let’s get started ! What are the basic Java programs?ġ. In this article, let’s see some of the important programs to understand Java fundamentals.īelow is the list of programs that I will be covering in this article. It is simple, robust and helps us to reuse the code. Java is one of the most popular programming languages that is being widely used in the IT industry.
