Finding the maximum or minimum element in an array.
Here’s an example Java program that finds the maximum and minimum elements in an array:
public class ArrayMinMax {
public static void main(String[] args) {
int[] numbers = {5, 2, 9, 1, 7, 3};
// Finding the maximum element
int max = numbers[0]; // Assume the first element is the maximum
for (int i = 1; i < numbers.length; i++) { if (numbers[i] > max) {
max = numbers[i];
}
}
System.out.println("Maximum element: " + max);
// Finding the minimum element
int min = numbers[0]; // Assume the first element is the minimum
for (int i = 1; i < numbers.length; i++) {
if (numbers[i] < min) {
min = numbers[i];
}
}
System.out.println("Minimum element: " + min);
}
}
In this program, we have an array called `numbers` with some integer values. We use two variables, `max` and `min`, to store the maximum and minimum elements respectively.
To find the maximum element, we assume the first element is the maximum and then iterate through the array. If we find a number greater than the current maximum, we update the `max` variable with that number.
Similarly, to find the minimum element, we assume the first element is the minimum and iterate through the array. If we find a number smaller than the current minimum, we update the `min` variable with that number.
Finally, we print the maximum and minimum elements using `System.out.println()`. When you run this program, it will output the maximum and minimum elements in the given array:
Maximum element: 9
Minimum element: 1
