maximum and minimum in an array in java code example
Example 1: Java program to find maximum and minimum number without using array
import java.util.Scanner;
public class MaximumMinimumWithoutArray
{
public static void main(String[] args)
{
Scanner sc = new Scanner(System.in);
System.out.println("Please enter total number: ");
int numbers = sc.nextInt();
int maximum = Integer.MIN_VALUE;
int minimum = Integer.MAX_VALUE;
System.out.println("Please enter " + numbers + " numbers.");
for(int a = 0; a < numbers; a++)
{
int current = sc.nextInt();
if(current > maximum)
{
maximum = current;
}
if(current < minimum)
{
minimum = current;
}
}
System.out.println("largest of " + numbers + " numbers is: " + maximum);
System.out.println("smallest of " + numbers + " numbers is: " + minimum);
sc.close();
}
}
Example 2: 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;
}
Example 3: 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;
}
