Well...then you will have to hardcode the value, like this:
String[] resultArray = {"a", "b", "c"};String[][] array = {{"a","b","c"},{"d","e","f"},{"g","h","i"}};
String[] resultArrayPtr = array[index];
if you want to copy you going to have iterate or to use clone.
Try this:
copies reference
String[][] array = {{"a","b","c"},{"d","e","f"},{"g","h","i"}};
String[] resultArray = array[0];
copies values
String[][] array = {{"a","b","c"},{"d","e","f"},{"g","h","i"}};
String[] resultArray = new String[array[0].length];
System.arraycopy(array[0],0, resultArray, 0, array[0].length);

String [] firstRow = array[0];
