sum of arrays

Guys, how can I make the sum of the first element an array with the last element of another array and so on and save them in another array :(?

Use indexing [0] for the first and [-1] to get the last

you only need one for loop to run from 0 to the size of the array (i) the counter for the second array should be declared outside of the array and decremented in the forloop (j) then simply calculate the values of the new array based on the indexes of the respective arrays within the loop using i & j

X= Array1[0] will give first element.. Y = Array2[Array2.length-1] will give you last element.. Add those save where you want.. Array3[i] = X+Y; Edit :Negetive index not work in java.. @Ananiya Jemberu
