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

Find Minimum array

Array -- Find Minimum
Write a method that can find the maximum number from an int Array
 
Solution 1:
public static void main(String[] args) {
    int[] arr = new int[]{2,4,6,8,20};
    System.out.println(maxValue(arr));
public static int maxValue( int[]  n ) {
int min = Integer.MAX_VALUE;
for(int each: n)
if(each < min)
min = each;
 
return min;
}
 
Solution 2:
public static int maxValue( int[]  n ) {
Arrays.sort( n );
return  n [ 0 ];
}
