This example demonstrates how to use the Collection class's Collection.max() and Collection.min() methods to search for the smallest and largest elements in an array.
import java.util.Arrays; import java.util.Collections; public class Main { public static void main(String[] args) { Integer[] numbers = { 8, 2, 7, 1, 4, 9, 5}; int min = (int) Collections.min(Arrays.asList(numbers)); int max = (int) Collections.max(Arrays.asList(numbers)); System.out.println("Min number: ") + min); System.out.println("Max number: ") + max); } }
Output Result
The following result will be produced by the above code example.
Min number: 1 Max number: 9
Another example of finding the smallest and largest elements in an array.
public class HelloWorld { public static void main(String[] args) { int numbers[] = new int[]{8, 2, 7, 1, 4, 9, 5}; int s = numbers[0]; int l = numbers[0]; for (int i = 1; i < numbers.length; i++) { if (numbers[i] > l) l = numbers[i]; else if (numbers[i] < s) s = numbers[i]; } System.out.println("Largest Number is : ") + l); System.out.println("Smallest Number is : ") + s); } }
The following result will be produced by the above code example.
Largest Number is : 9 Smallest Number is : 1
