Java Program To Find the Smallest and Largest Numbers in an Array
Find the Largest and Smallest Number in an Array means how to find the largest and smallest numbers in an array. In this example, we use 10 numbers in which we find the smallest and largest value.
Program to Find Smallest and Largest in Java Array
public class FindLargeSmall
{
public static void main(String[] args)
{
//array of 10 numbers
int numbs[] = new int[]{32,43,53,54,32,65,63,98,43,23};
//assign the first element of an array to the largest and smallest
int smallestno = numbs[0];
//assign the first element of an array to the smallest
int largetstno = numbs[0];
//assign the first element of an array to the largest
//for loop is used to find the largest and smallest from start to end digit
for(int i=1; i< numbs.length; i++)
{
if(numbs[i] > largetstno) //condition check if true then
largetstno = numbs[i]; //assign the value to largestst
else if (numbs[i] < smallestno)
smallestno = numbs[i];
}
System.out.println(“Largest Number is : ” + largetstno);
System.out.println(“Smallest Number is : ” + smallestno);
}
}
Explanation ….
In the above program, we use an array to find the smallest and largest numbers. We enter 10 numbers in an array, and by using a for loop, we can find the result. Searching always starts with zero. The index of the elements in an array always starts with 0.
Program to Find Smallest and Largest in Java Array using Scanner class.
import java.util.Scanner;
public class SmallestLargestInArray {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
// Input array size
System.out.print(“Enter number of elements: “);
int n = sc.nextInt();
int[] arr = new int[n];
// Input array elements
System.out.println(“Enter ” + n + ” numbers:”);
for (int i = 0; i < n; i++) {
arr[i] = sc.nextInt();
}
// Initialize smallest and largest
int smallest = arr[0];
int largest = arr[0];
// Traverse array
for (int i = 1; i < n; i++) {
if (arr[i] < smallest) {
smallest = arr[i];
}
if (arr[i] > largest) {
largest = arr[i];
}
}
// Output result
System.out.println(“Smallest number: ” + smallest);
System.out.println(“Largest number: ” + largest);
sc.close();
}
}
