Answer 1

public class MyClass {
    public static void main(String args[]) {
        int array[] = {5, 3, 7, 9, 6, 4};
        int size = array.length;

        for (int i = 0; i < size; i++) {
            for (int j = i + 1; j < size; j++) {
                if (array[i] > array[j]) {
                   int temp = array[i];
                   array[i] = array[j];
                   array[j] = temp;
                }

public class MyClass {
    public static void main(String args[]) {
        int arr[] = {3, 4, 9, 6, 7, 1, 2, 5};
        int len = arr.length;
        int max, secondlargest;
        
        max = secondlargest = Integer.MIN_VALUE;
 
        for (int i = 0; i < len; i++) {
            if(arr[i] > max) {
                secondlargest = max;
                max = arr[i];
            }
            else if(arr[i] > secondlargest && arr[i] < max) {
                secondlargest = arr[i];
            }
        }
        System.out.println(secondlargest);
    }
}
