Noob: Declare & Initialise String Array

30 Days Ago

Hello

I am just learning Java. I have some elmentary questions. In my code below there are 3 errors that occur:
- How do I declare a string array of size 5 in Java correctly?
- How do I cin :p, take in a string array element. Ie, in C++ cin >> string[i], how would I write that in Java?
