how to find the max value in an array in java code example

Example 1: max in array java

// Initializing array of integers 
        Integer[] num = { 2, 4, 7, 5, 9 }; 
// using Collections.min() to find minimum element 
        // using only 1 line. 
        int min = Collections.min(Arrays.asList(num)); 
  
        // using Collections.max() to find maximum element 
        // using only 1 line. 
        int max = Collections.max(Arrays.asList(num));

Example 2: 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)
   {
      int maximumValue = arr[0];
      for(int a = 1; a < arr.length; a++)
      {
         if(arr[a] > maximumValue)
         {
            maximumValue = arr[a];
         }
      }
      return maximumValue;
   }
   // java min of array
   public static int minNumber(int[] arr)
   {
      int minimumValue = arr[0];
      // find minimum value in array java
      for(int a = 1; a < arr.length; a++)
      {
         if(arr[a] < minimumValue)
         {
            minimumValue = arr[a];
         }
      }
      return minimumValue;
   }
}
