I wrote a code that find average of 2d array list, after running the code, The error message says

"""" Averager2D.java:84: error: '.class' expected return double; ^ 1 error"""""

Could you please let me know whats wrong with the code and could you fix it aswell?

public static double average(int[][] aa)

{

double total = 0;

int count = 0;

for (int i = 0; i

for(int j =0; j < aa[i].length; j++){

int element = aa[i][j];

total = total + element;

count++;

}

return count;

}

double average = total / count;

//end code..

}

Find the average of the even elements of a two-dimensional array and return it

*/

public static double averageEvens(int[][] aa)

{

double total = 0;

int count = 0;

for(int i=0; i < aa.length; i++){

for (int j =0; j < aa[i].length; j++){

int element = aa[i][j];

if(element %2==0){

total = total + element;

count++;

}

}

return double;

}
