How to find the largest number in an array java?

One of the ways is to sort the array, then print the last element of the sorted array.

In Java, you can make use of the following code

import java.util.Scanner;

public class Assignment{

public static void main(String [] args)

{

int n;

Scanner input = new Scanner(System.in);

System.out.print("Array Length: ");

n = input.nextInt();

int [] myarray = new int[n];

System.out.print("Input Array: ");

for(int i=0;i<n;i++)

{

           myarray[i]=input.nextInt();

}

int temp;  

for (int i = 0; i < n; i++)  

       {  

           for (int j = i + 1; j < n; j++)  

           {  

               if (myarray[i] > myarray[j])  

               {  

                   temp = myarray[i];  

                   myarray[i] = myarray[j];  

                   myarray[j] = temp;  

               }  

           }  

       }  

           System.out.println(myarray[n - 1]);

       }

}

Explanation:

This line declares n as length of array

int n;

Scanner input = new Scanner(System.in);

This line prompts user length of array

System.out.print("Array Length: ");

This line gets the user input

n = input.nextInt();

An empty array pf length arrowed

int [] myarray = new int[n];

This line prompts user array elements

System.out.print("Input Array: ");

The following iteration gets array element from user

for(int i=0;i<n;i++)

{

           myarray[i]=input.nextInt();

}

This line declares a temporary variable temp

int temp;

This iterations iterates through the elements of rge array

for (int i = 0; i < n; i++)  

       {  

           for (int j = i + 1; j < n; j++)  

           {  

The following if condition checks for the larger of two variables and swap their position

               if (myarray[i] > myarray[j])  

               {  

                   temp = myarray[i];  

                   myarray[i] = myarray[j];  

                   myarray[j] = temp;  

               }  

           }  

       }  

This line prints the largest number of the array

           System.out.println(myarray[n - 1]);
