Java: Find the second smallest element in an array
Java Array: Exercise-18 with Solution
Write a Java program to find the second smallest element in an array.
Pictorial Presentation:
Sample Solution:
Java Code :
// Import the necessary Java utilities package.
import java.util.Arrays;
// Define a class named Exercise18.
public class Exercise18 {
// The main method where the program execution starts.
public static void main(String[] args) {
// Create an integer array with numeric values.
int[] my_array = {-1, 4, 0, 2, 7, -3};
// Print the original numeric array.
System.out.println("Original numeric array : " + Arrays.toString(my_array));
// Initialize variables to find the minimum and second minimum values.
int min = Integer.MAX_VALUE;
int second_min = Integer.MAX_VALUE;
// Iterate through the array to find the second lowest number.
for (int i = 0; i < my_array.length; i++) {
if (my_array[i] == min) {
// If the current element equals the minimum, update the second minimum.
second_min = min;
} else if (my_array[i] < min) {
// If the current element is less than the minimum, update both minimum and second minimum.
second_min = min;
min = my_array[i];
} else if (my_array[i] < second_min) {
// If the current element is less than the second minimum, update the second minimum.
second_min = my_array[i];
}
}
// Print the second lowest number found.
System.out.println("Second lowest number is : " + second_min);
}
}
Sample Output:
Original numeric array : [-1, 4, 0, 2, 7, -3] Second lowest number is : -1
Flowchart:
Java Code Editor:
Previous: Write a Java program to find the second largest element in an array.
Next: Write a Java program to add two matrices of the same size.
