In this article, we briefly explored different ways of number formatting in Java. As we can see, there’s no one best way to do this. Many approaches can be used, as each of them have their own characteristics. As always, the code for these examples is availableover on GitHub....
This Java program demonstrates how to check for Xylem and Phloem numbers using string operations instead of mathematical calculations. import java.util.*; class XylemPhloemNumber { public static void main(String[] args) { Scanner sc = new Scanner(System.in); System.out.print("Enter a number:...
The following Java program checks whether a given number is a Giuga number. Open Compiler public class GiugaChecker { // Method to check if a number is prime public static boolean isPrimeNumber(int number) { if (number <= 1) return false; // Numbers <= 1 are not prime for (int i...
In this program, you'll learn to check whether a given number is positive or negative. This is done by using a if else statement in Java.
System.out.println("15 in Hexa is " + String.format("%x", y)); with System.out.println("15 in Hexa is " + String.format("%08x", y)); Which gives the output 16 in hexa is 000000f Exercise Write a program that will print numbers 0 to 255 in hexadecimal. It should have 2 ...

2. Decimal Numbers in Java Java provides two primitive types that we can use for storing decimal numbers:floatanddouble.Doubleis the default type: double PI = 3.1415; However, weshould never use either type for precise values, such as currencies. For that, and also for rounding, we can us...
What is Magic Number in Java? A number is considered a magic number if the sum of its digits, when repeatedly added until a single digit is obtained, equals 1. This process involves adding the digits of the number together, then adding the digits of the resulting sum, and so on, until...
