Find the max or min value in an array java code example
Example 1: max in array java
Integer[] num = { 2, 4, 7, 5, 9 };
int min = Collections.min(Arrays.asList(num));
int max = Collections.max(Arrays.asList(num));
Example 2: 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);
int minimum = minNumber(arrNumber);
System.out.println("Minimum value : " + minimum);
}
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;
}
public static int minNumber(int[] arr)
{
int minimumValue = arr[0];
for(int a = 1; a < arr.length; a++)
{
if(arr[a] < minimumValue)
{
minimumValue = arr[a];
}
}
return minimumValue;
}
}
