How to find the min value in an array in Java

Answer 1

public class MyClass {
    public static int min(int[] arr) {
        int minval = arr[0];   
        for (int i = 1; i < arr.length; i++) {
            if (arr[i] < minval) {
                minval = arr[i]; 
            }
        }
        return minval;
    }
    public static void main(String args[]) {
        int[] arr = new int [] {3, 4, 9, 2, 7, 8, 5};   
 
        System.out.println(min(arr));
    }
}

public class MyClass {
    public static void main(String args[]) {
        int[] arr = new int [] {3, 4, 9, 2, 7, 8, 5};   
        
        int min = Arrays.stream(arr).min().getAsInt();
  
        System.out.println(min);
    }
