Use the following declarations with questions through 1 through 3. into myCard = new int[5] [5]; String[] D names = { {"NC", "SC"}, {"GA", "FL"}, {"AL", "GA"}, {"VA", "TN"} }; String ssNum = "344-86-7609"; Bitset mySet = new BitSet(15); 2. Write one line of code to do each of the following. (3 points each) (a) Concatenate the string "home" to the string in the second row, first column of matrix names. The word concatenate means to add another string on to the end of an existing string. (b) Print out the middle two digits of the string ssNum shown above. You must use indexOf and substring in your answer. Assume the middle two digits are always preceded by the character
