Find minimum and maximum values in a java array

// Find minimum and maximum values in a java array
public class MaxMinValueInArray
{
   public static void main(String[] args) 
   {
      int[] arrNumber = new int[]{50, 150, 250, 500, 160, 530};
      int maximum = maxNumber(arrNumber);
      System.out.println("Maximum value : " + maximum);
      // calling min function java
      int minimum = minNumber(arrNumber);
      System.out.println("Minimum value : " + minimum);
   }
   // java find max in array
   public static int maxNumber(int[] arr)

how to get the max value of an array java

public static double arrayMax(double[] arr) {
    double max = Double.NEGATIVE_INFINITY;

    for(double cur: arr)
        max = Math.max(max, cur);

    return max;
}

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;
	}

find minimum number in array java

public class MinimumNumber{
  public static void main(String[] args){
    int[] arr=new int[]{2,3,4,1};
    int min=arr[0];
    for(int i=0;i<arr.length;i++){
      if(arr[i]<min){
        min=arr[i];
      }
    }
    System.out.println("Minimum Number in array:"+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];
