How to print out a random String from an array in Java

Question

Hi I have been trying to make my first game for a while but have run into difficulty. I want to pull a randomized String from an array of Strings and then print it out but I have errors in my code. I have looked all over but I can't find the solution. Here is the code: (I have already declared the currentRoom varible)

 int currentRoom;
String [][] rooms = {{"Start", "Treasure Room1"}, {"Goblin Home1", "Spider Nest1"}};
Random rand = new Random()
currentRoom = rooms [rand.nextInt( rooms.length)];
System.out.println(currentRoom);

I have an error on my currentRoom variable in line 6 and I think that is messing everything up, but I don't know so the mistake could be anywhere.

Any help is appreciated:)

Answer 1

Two things you have to change:

1. currentRoom should be String Array

2. Printing string array should be done using Arrays.toString

    String[] currentRoom;
    String [][] rooms = {{"Start", "Treasure Room1"}, {"Goblin Home1", "Spider Nest1"}};
    Random rand = new Random();
    currentRoom = rooms [rand.nextInt(rooms.length)];
    System.out.println(Arrays.toString(currentRoom));
   

Sample Output

[Goblin Home1, Spider Nest1]

Hope this helps!

Why do you need a 2D array of strings? I think you can manage with a 1D array instead.

String currentRoom;
String[] rooms = {"Start", "Treasure Room1", "Goblin Home1", "Spider Nest1"};
Random rand = new Random();
currentRoom = rooms [rand.nextInt( rooms.length)];
System.out.println(currentRoom);

String currentRoom;
String [][] rooms = {{"Start", "Treasure Room1"}, {"Goblin Home1", "Spider Nest1"}};
Random rand = new Random();
int rnd = rand.nextInt( rooms.length);
currentRoom = rooms [rnd][0] + ":"+ rooms [rnd][1];
System.out.println(currentRoom);
