Java code to find largest elements of an Array

Java code to find largest elements of an Array

In this tutorial, we will discuss a concept of Java code to find the largest elements of an Array

In this topic, we learn how to find largest element of an array(Collection of elements)

This program gets “n” number of elements and Enter the elements of the array as input from the user. then, this program finds and displays the largest elements from the array using for loops.

In this programs, we can see step by step procedure for completion of the program.

• array declaration
• Essential variable declaration
• Get input from the user for array length
• Get input from the user for array elements
• loop for finding largest value
• Display result on the screen

Find largest value – integer Array

import java.util.Scanner;
class Array_Large{
public static void main (String args[]){
int max;//variable declaration
System.out.println("Enter the number of elements in an array: ");
Scanner scan=new Scanner(System.in);
int n=scan.nextInt();//get input from user for array length
int[] arr=new int[n];//declaring an array of n elements

//for loop for get input from user
for(int i=0; i<n; i++){
System.out.print("Enter the element "+(i+1)+" :");//n elements
arr[i]=scan.nextInt();//get input from user for array
}
max=arr[0];
for(int i=0; i<n; i++){
if(max<arr[i]){
max=arr[i];
        }
}
System.out.println("\nThe largest value is: "+max);
}//display result on the screen
}

When the above code is compiled and executed, it produces the following results

Enter the number of elements in an array:
5
Enter element 1: 67
Enter element 2: 98
Enter element 3: 64
Enter element 4: 90
Enter element 5: 23

The largest value is: 98

 

Find largest value – float Array

import java.util.Scanner;
class Large_num{
public static void main (String args[]){
Scanner scan=new Scanner(System.in);
System.out.print("Enter the number of elements in an array: ");
double max;
int n=scan.nextInt();//get input from user for array length
double arr[]=new double[n]; //declaring an array of n elements

//for loop takes input from user
for(int i=0; i<n; i++){
   System.out.print("Enter element "+(i+1)+": ");
   arr[i]=scan.nextDouble();//takes input from user for array
   }
   max=arr[0];
   for(int i=0; i<n; i++){
     if(max<arr[i]){
       max=arr[i];
     }
   }
   System.out.print("\nThe largest value is: "+max);
}//display result on the result
}

When the above code is compiled and executed, it produces the following results

Enter the number of elements in an array: 5
Enter element 1: 4.2
Enter element 2: 2.4
Enter element 1: 6.7
Enter element 2: 9.5
Enter element 2: 5.6

The largest elemets is: 9.5
