Example: Java Program to Check a Leap Year public class Main { public static void main(String[] args) { // year to be checked int year = 1900; boolean leap = false; // if the year is divided by 4 if (year % 4 == 0) { // if the year is century if (year % 100 == 0)...
We check if num is exactly divisible by any number from 2 to num - 1. If we find a factor in that range, the number is not prime, so we set flag to True and break out of the loop. Outside the loop, we check if flag is True or False. If it is True, num is not a prime...
The value of the first number and the second number are switched using a temporary variable, as can be seen in the output. Swap Two Numbers in Java Without Using a Temporary Variable Previously, we observed the use of a temporary variable to swap two numbers in Java. Let’s now examine ...
Primes are central in number theory because of the fundamental theorem of arithmetic: every natural number greater than 1 is either a prime itself or can be factorized as a product of primes that is unique up to their order.Sample Solution:Java Code:import java.util.stream.IntStream; public ...
Learn to write a simple java program to verify if a given number is deficient number or not. The value 2n − σ(n) is called the number’s deficiency.
Now we need to check the streaming condition for and . Unfortunately, this is never going to hold: is always productive, so will only take production steps and never consume any input. The problem is that is too aggressive, and we need to use the more cautious flushing version of streaming...
package. Just like we create our own stack, we have predefined methods in the Stack class to push, pop, peek an element from the stack and methods to check whether the stack is empty or not, to iterate the stack, etc. The Stack program in Java using the Java Stack class is shown ...
1 Gallon is a measure of the fuel used. To convert 1 Gallon into the much more normally used SI units, 1 Gallon = 3.785 litres. Hence, the lower the gallons of fuel is consumed, the better is its mileage. Thus, the various methods to calculate Miles per Gallon in Java Programming are...

2)In Count function for loop iterates through i=0 to i<n if a[i]!=-1 a)Compare present element with next elements of the array using for loop from j=i+1 to j<n. If any element is equal to the present element then increase the count by 1. Repeats until all iterations of j....
