Final answer:
To declare a string array named cityName to hold 26 string elements in Java, you can use the statement: String[] cityName = new String[26];
Step-by-step explanation:
Java statement: String[] cityName = new String[26];
This single Java statement declares a string array named cityName to hold 26 string elements. The array elements are not initialized in this statement, meaning they do not have any initial values. To access or manipulate individual elements in the array, you can use their index positions (0 to 25, in this case).
