How to find the max value in int array with Java

Answer 1

public class MyClass {
    public static int max(int[] arr) {
        int maxval = arr[0];   
        for (int i = 1; i < arr.length; i++) {
            if (arr[i] > maxval) {
                maxval = arr[i]; 
            }
        }
        return maxval;
    }
    public static void main(String args[]) {
       int[] arr = new int [] {3, 0, 9, 7, 8, 5};   

        System.out.println(max(arr));
    }
}
