Array Programs

Min & Max from given Array

public void findMinMax(int[] arr) {
    int min = arr[0];
    int max = arr[0];

    for(int i=0; i<arr.length;i++) {
        if(arr[i] < min) {
            min = arr[i];
        }
        else if(arr[i] > max) {
            max = arr[i];
        }
    }

    System.out.println(max + " "  + min);
}

Second Max from given Array

public void findSecondMax(int[] arr) {
    int max = arr[0];
    int secondMax = arr[0];

    for(int i=0;i<arr.length; i++) {
        if(arr[i] > max) {
            secondMax = max;
            max = arr[i];
        }else if (arr[i]> secondMax) {
            secondMax = arr[i];
        }
    }

    System.out.println(max + " " + secondMax);
