The number which is divisible by itself and 1 is known as Prime Number, eg :- 5 is a prime number because it is only divisible by itself and 1.
Using Java
import java.util.Scanner;
class PrimeCheck
{
public static void main(String args[])
{
int temp;
boolean isPrime=true;
Scanner scan= new Scanner(System.in);
System.out.println("Enter any number:");
//capture the input in an integer
int num=scan.nextInt();
scan.close();
for(int i=2;i<=num/2;i++)
{
temp=num%i;
if(temp==0)
{
isPrime=false;
break;
}
}
//If isPrime is true then the number is prime else not
if(isPrime)
System.out.println(num + " is a Prime Number");
else
System.out.println(num + " is not a Prime Number");
}
}
Output:
Enter any number:
19
19 is a Prime Number
Output 2:
Enter any number:
6

If the year is evenly divisible by 4, go to step 2. Otherwise, go to step 5.2. If the year is evenly divisible by 100, go …

Since this area is limited, it is required to manage this area efficiently by removing the objects that are no longer in use. The process of removing unused …
Continue reading Garbage Collection in Javafinal keyword can be used along with variables, methods and classes. 1) final variable final variables are nothing but constants. We cannot change the value of a final variable once it is initialized. Lets have a look at the below code: Note: It is considered as a good practice to have constant names in UPPER …
Continue reading Final Keyword In JavaYou must have seen public, private and protected keywords while practising java programs, these are called access modifiers. An access modifier restricts the access of a class, constructor, data member and method in another class. In java we have four access modifiers: 1. default 2. private 3. protected 4. public 1. Default access modifier When …

What is encapsulation? The whole idea behind encapsulation is to hide the implementation details from users. If a data member is private it means it can only be accessed within the same class. No outside class can …
Continue reading Encapsulation in JavaA class that is declared using “abstract” keyword is known as abstract class. It can have abstract methods(methods without body) as well as concrete methods (regular methods with body). A normal class(non-abstract class) cannot have abstract methods. An abstract class can not be instantiated, which means you are not allowed to create an object of …
