how to find 2nd largest array if array values like{10,20,92,81,92,34}

``````  int[] arr = {10, 20, 91, 81, 92, 34};
//let pretend  that the largest number is 10
int maxVal = arr[0];
int secLargestNum = 0;
for (int i = 1; i < arr.length; i++) {
//check if the number at the postion i is greater than the    maxVal which is 10
if (arr[i] >= maxVal) {
//if the condation is true then assign secLargestNum to maxVal .. now secLargestNum will become 10
secLargestNum = maxVal;
maxVal = arr[i];

} else if (arr[i] > secLargestNum) {

secLargestNum = arr[i];

}
}

System.out.println(secLargestNum);

I tried with array 10,20,92,81,92,34 but it didn't seem to work

I hope this will get you start on something .. if I figure out another solution I will update the answer

sk8ergirl: don't spoonfeed, just explain the possible algorithms to go through.
anjijava16: either sort the array and take the element with the second highest index, or iterate over the array for each element (if you really are not allowed to sort the array, which I doubt) until you've found an element that has only one value higher than the value of the element you're checking for.
