In this article, we will see a menu driven program to check if the entered character is number, string or special character by Java programming language. We will be implementing the application using a switch case. To show you some instances  Instance-1 Suppose the entered character is ‘a’ then the output should be “Entered character is a String”. Instance-2 Suppose the entered character is ‘1’ then the output should be “Entered character is a number”. Instance-3 Suppose the entered character is ‘$’ then the output should be “Entered character is a Special character”. Syntax To check whether ... Read More

A number is said to be a positive number if it is greater than 0 and if it is less than 0 then it is called a negative number. The negative number is followed by a minus sign (-) to identify it as a negative number. A number is said to be an even number if it is divisible by 2 else it is called an odd number. In this article, we will see how to check if a number is positive, negative, or even, odd by using Java programming language. We will be implementing the application using a switch ... Read More

A circle is a round shape two-dimensional diagram which has no corners. Every circle has an origin point and every point on the circle maintains equal distance from the origin. The distance between the origin and a point in a circle is known as Radius of the circle. And similarly, if we draw a line from one edge to another edge of the circle and the origin is held in the middle of it, that line is known as diameter of the circle. Basically, the diameter is double of the length of the radius. Chord of the circle refers to ... Read More

As per the problem statement we have to write a Java program to replace each element of the array with its next element. In Java, the array is an object. It is a non-primitive data type which stores values of similar data types. Before discussing the solution for the given problem, let's understand the problem statement with an example − Example Scenario: Input: arr[] = {12, 23, 11, 64} Output: updated array = {23, 11, 64, 12} Algorithm Follow the steps below to replace each element of the array with its next element − Step 1 − Declare ...

Roman Number − Based on the ancient Roman system, symbols are used to represent the numbers. These numbers are known as Roman numbers. Symbols are I, V, X, L, C, D, and M use respectively for 1, 5, 10, 50, 100, 500, and 1, 000. Integer Number − Integer number is nothing but the whole number which consists ofpositive, negative and zero value. Fraction numbers are not integers. Here we have set the symbol values as per their integer values. Whenever a roman number is entered as input we divide into units and then calculate the appropriate roman number. I ... Read More

A number is said to be an Autobiographical number, if the number’s first digit represents the number of 0 available in the given number, the second number represents the number of 1 present in the given number, the third number represents the number of 2 present in the given number and so on. In simple terms, if the given number’s digits from left to right represent the frequency of 0, 1, 2, 3, 4.... N respectively present in the given number then that number is known as Autobiographical number. Some examples of Autobiographical numbers are: 1210, 2020, 21200, 3211000, 42101000 ... Read More

Two numbers are said to be Coprime numbers, if the maximum common divisors is 1 for those two numbers. For more clarification, there might be multiple divisors for any number and in some scenarios, there are some common divisors that are also present between two number’s divisors. So, if in any case we get the maximum common divisors between two numbers are 1, then those two numbers are known as coprime numbers. Simply, it means those numbers do not have any other common factors other than 1. In other words, we can say that these two numbers are mutually prime ... Read More

A line consists of an infinite number of points. In two-dimensional coordinate system we can define every point with two values i.e. X and Y. A point basically situated on the left side or right side or it can be on the line itself and this can be defined only if we have the coordinates of it. In this program we are going to use the cross-product method to find the direction of the point. Cross- Product method is used to find the third vector from two vectors by cross multiplying both the vectors. In our case if we cross ... Read More
