Find min in array java

private static int findMin(int[] array) {
		int min = array[0];
		for(int i=1;i<array.length;i++) {
			if(min > array[i]) {
				min = array[i];
			}
		}
		return min;
	}

How to get the max value of an array java

import java.util.Random;

public class Main {

public static void main(String[] args) {
   int a[] = new int [100];
   Random rnd = new Random ();

    for (int i = 0; i< a.length; i++) {
        a[i] = rnd.nextInt(99-0)+0;
        System.out.println(a[i]);
    }

    int max = 0;          

    for (int i = 0; i < a.length; i++) {
        a[i] = max;


        for (int j = i+1; j<a.length; j++) {
            if (a[j] > max) {
               max = a[j];
            }

        }
    }

    System.out.println("Max element: " + max);
}
}

Finding min and max from given number in java
