max and min in array in java code example

Example 1: 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;
   }
}

Example 2: 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;
}
