Java program Biggest number among N Integers

In order to find biggest number from unordered (not sorted) set of N numbers, a sequential search mechanism used, in which search starts from zero index to N-1 index.

A Biggest number from array numbers - Pseudocode

    Read a integer N

    initialize memory array of N element

    Read integers and store into an array
    
    set biggest = 0;

    for n=0  to N

      check array[n] > biggest  , set biggest = array[n]

    end for   
  
    print biggest
  

A Biggest number from array of numbers - Java program

The Java program read N integers from user via keyboard and stored on an array. It has a for-loop to start sequential search to find a biggest number from this array of numbers.

 

import java.io.IOException;
import java.util.Scanner;


public class BiggestAmongN 
{

 public static void main(String[] args) throws IOException 
  {
  
  Scanner sc =new Scanner(System.in);  
  System.out.println("Enter Number of Elements N");
  int N =sc.nextInt();      
  int array[] =new int[N];  
  
  for (int n=0;n<N;n++)
  {
   System.out.println("Enter " + n +  " Element ");        
          array[n] = sc.nextInt();
  }
  sc.close();
  
  int biggest=0;
  for (int n=0;n<N;n++)
  {
    if (   array[n] > biggest )
      biggest=array[n];
  }
  
 System.out.println("The Biggest value among N Elements is :
                                     " + biggest);
 }

}


 

Biggest Number - Java program Output

Enter Number of Elements N
5
Enter 0 Element 
20
Enter 1 Element 
38
Enter 2 Element 
43
Enter 3 Element 
67
Enter 4 Element 
16

The Biggest value among N Elements is : 67
