Find the Minimum and Maximum Element in an Array

Find the Minimum and Maximum Element in an Array

Go through the array and keep track of the highest and lowest values:

Example

int[] numbers = {45, 12, 98, 33, 27};
int max = numbers[0];
int min = numbers[0];
for (int n : numbers) {
  if (n > max) {
    max = n;
  }
if (n < min) {
  min = n;
}
}
System.out.println("Max: " + max);
System.out.println("Min: " + min);

Explanation: Start by assuming the first element is both the maximum and minimum. As you loop through the array, update max if you find a larger number and min if you find a smaller number.
