Harshad numbers are those integers which are divisible by the sum of the digits of the number. Harshad numbers were defined by a mathematician from India, D. R. Kaprekar. Harshad numbers are also called Niven numbers. For example, the number 198. Sum of the digits of the number, 198 => 1 + 9 + 8 = 18, and, 18 …
A BMI calculator helps in calculating Body-Mass Index. Body Mass Index is a tool or a formula which helps us in knowing whether a person’s body weight is appropriate or not. It measures body weight with respect to the person’s height. BMI is calculated by dividing a person’s weight in kilograms by square of height …
Writing clean code is a matter of skill as much as it is a personal habit. For 25 years, since the Java programming language was launched it has evolved, and the Java coding practices have advanced too. To achieve your desired goal of the software, application or product you intend to produce, you need to …
Automorphic numbers are those numbers that when squared have the exact same end digits as the number. For example, the number 376. Now the square of the number, 376 is 141376. The last three digits of the square are exactly like the number themselves. Hence, 376 is an Automorphic Number. However, let the number is …
Pronic numbers are those numbers who can be written as a product of two consecutive integers. It means, they are of the form: P = n * (n + 1) For example, the number 56 can be written as 7 * 8, that is, a product of two consecutive integers. Hence, the number 56 is …
We can square a number in Java in no less than two different ways. Let have a look on each method one by one. Method1: Multiplying the Number by Itself To square a number x, we can multiply the number by itself. Y = x * x. Java Program for the above method. import java.util.Scanner; …
Random numbers may be required for sorts of programming jobs. For example, statistical sampling, computer simulation, cryptography, and other areas where producing random unpredictable results is desirable. Java provides certain ways in which we can generate random numbers. Although, the generated random numbers are pseudo-random, they get the work done mostly. We can generate random …
We often are stuck at discussion about Objects and their references, it is known fact that unlike C or C++, java doesn’t allows variable access using pointers, well why it does not allows is itself a whole topic which you can read here. Today we will discuss about what all types can be given to …
