Read MoreJava Program for Common Divisors of Two Numbers
In this article, we will learn to find the common divisors of two numbers using Java. The program will use a recursive method to calculate the greatest common divisor (GCD) of the two numbers, and then determine how many divisors are shared by both numbers. The output will display the total number of common divisors. Problem Statement Write a Java program to find and count the common divisors of two given numbers. Below is a demonstration of the same − Input val_1= 68 val_2= 34 Output The common divisors between the two numbers is4 Steps to find the common divisors ...
Read MoreJava program to print a Fibonacci series
The Fibonacci Series generates subsequent numbers by adding two previous numbers. The Fibonacci series starts from two numbers − F0 & F1. The initial values of F0 & F1 can be taken as 0, 1, or 1, 1 respectively. Fn = Fn-1 + Fn-2 Problem Statement Write a program in Java program to print a Fibonacci series. Input Run the program Output 1 1 2 3 5 8 13 21 34 55 The above output is obtained when the values of n=10. Different approaches to print a Fibonacci series Following are the different approaches to printing a Fibonacci series − ...
Read MoreJava program to show inherited constructor calls parent constructor by default
In this article, we will learn about constructors in Java. Constructors initialize objects when they are created. We will also see how the parent constructor is called in inheritance. Problem StatementWe will demonstrate possible approaches to show how the inherited constructor calls the parent constructor by default.Different approaches The following are the different approaches to show how the inherited constructor calls the parent constructor by default− Demonstrating inheritance properties ...
Read MoreJava program to get the current value of the system timer in nanoseconds
In this article, we use the System.nanoTime() method in Java to get the current value of the system timer in nanoseconds. It returns the current value of the most precise available system timer, in nanoseconds. Problem StatementGiven that you need to get the current value of the system timer in nanoseconds, write a Java program that retrieves this value using the System.nanoTime() method.Input There is no specific input as the program retrieves the system's current time in nanoseconds directly.Output Current Value: 49908709882168 nanoseconds Steps to get the current value of the system timer in nanosecondsThe following are the ...
Read MoreJava program to get number of elements with odd factors in given range
In this article, we will learn how to count the number of elements with odd factors (i.e., perfect squares) in a given range using Java. Perfect squares have odd divisors, and we can calculate them by counting the perfect squares in the specified range. Problem StatementGiven a range defined by a lower and upper bound, write a Java program to calculate how many numbers in this range have odd factors (i.e., perfect squares).Input Lower Range: 55Upper Range: 1000Output The number of elements with odd factors between 55 and 1000 is: 24 Steps to calculate the number of elements with ...
