Finding the Largest element of the array

Here we’ll code a Java program for finding the largest element of the array. We’ll consider an integer array and compare all the elements of the array for finding the largest element. Its a pretty simple code, let’s see an algorithm for finding the largest element of the array.

Algorithm for Finding the largest element of the array

Step 1 – Initialize a variable len, for storing the length of the array.
Step 2 – Accept the length of the array.
Step 3 – Initialize an array.
Step 4 – Accept the input, using for loop.
Step 5 – Store the first element of the array in min.
Step 6 – Initialize a variable large, for storing the largest element of the array.
Step 7 – Compare all the elements of the array with large, and use a if condition for comparing all the array elements with large.
Step 7 – If there’ll be any element larger than large, store it value in large.
Step 8 – Print large.

JAVA Program for finding the Largest number in an array

import java.util.*;
public class first 
{
    public static void main(String[] args) 
    {
        System.out.print("Enter the length of the array : ");
        Scanner sc=new Scanner(System.in);
        int len=sc.nextInt();
        int[] arr=new int[50];
        System.out.print("Enter the elements of the array : ");
        for(int i=0;i<len;i++)
        {
            arr[i]=sc.nextInt();
        }
        int large = arr[0];
        for(int i=0;i<len;i++) { if(arr[i]>large)
            {
                large=arr[i];
            } 
        }
        System.out.print("The largest element of the array : "+large);
    }
}

Output

Enter the length of the array : 5
Enter the elements of the array : 
2
35
45
877
54
The largest element of the array : 877
