Factoring in java program

this program will show how to get the factorial using java program.

public class NumberFactorial {

public static void main(String[] args) {

int number = 5;

/*
* Factorial of any number is !n.
* For example, factorial of 4 is 4*3*2*1.
*/

int factorial = number;

for(int i =(number - 1); i > 1; i--)
{
factorial = factorial * i;
}

System.out.println("Factorial of a number is " + factorial);
}
}

Find Largest and Smallest Number in an Array using java

/*
Find Largest and Smallest Number in an Array Example

public class FindLargestSmallestNumber {

public static void main(String[] args) {

//array of 10 numbers
int numbers[] = new int[]{32,43,53,54,32,65,63,98,43,23};

Output of this program would be
Largest Number is : 98
Smallest Number is : 23

Even or Odd program using java

This program will determine if the number inputted by the user is even or odd.

we use here a modulo operator to get the even or odd numbers.

Modulo - this operator use in programming to get the remainder.

sample program:

import java.util.Scanner;

public class EvenOdd
{
public static void main(String args[])
{
Scanner input=new Scanner(System.in);

int num;

System.out.print("Enter a number:");
num=input.nextInt();

if(num%2==0)
{
System.out.print("Even number");
}
else if(num%2==1)
{
System.out.print("Odd Numbers");
}
}
}

Computng the area of circumference usign java

This program in java will compute the area of circumference .

Simple String program

import java.io.*;

public class javastring sample
{
public static void main(String args[])
{
/* string in java represents the character sequence */

/* create string empty*/

String s1=new String(" ");

/* create new string object whose content whose content whould be "Hello world"*/
String S2=new String("Hello World");


/* getting the length of the string */

System.out.print(s2.length());



}
}
