Revise the meanmedian class so that the user can enter any number of values up to 20. if the list has an even number of values, the median is the numeric average of the values in the two middle positions. allow the user to enter to quit entering numbers. import java. util.*; class meanmedian2{public static void main(string[] args){// int[] nums; int num = 0; string entry; string list = "you entered: "; int a, b; int temp; double median; int total = 0; double mean = 0; final int quit = ; int size = 0; for(a = 0; num ! = quit & & a < nums. length; ++a){// your code here}system. out. println("size is " + a); if(num ! = quit)size = nums. length; elsesize = a - 1; system. out. println("size is " + size); system. out. println(list); int comparisonstomake = size - 1; for(a = 0; a < size - 1; ++a){for(b = 0; b < comparisonstomake; ++b){if(nums[b] > nums[b + 1]){temp = nums[b]; nums[b] = nums[b + 1]; nums[b + 1] = temp; }}--comparisonstomake; } // your code heresystem. out. println("the mean is " + mean +" and the median is " + median); }}
