Concatenate two arrays
Array -- Concatenate two arrays
Write a return method that can concatenate two arrays
Solution:
public static int[] concatTwoArrays(int[] arr1 , int[] arr2) {
int[] result = new int[arr1.length + arr2.length];
int i = 0;
for(int each: arr1) {
result[i] = each;
i++;
}
for(int each: arr2) {
result[i] =each;
i++;
}
return result;
