使番石榴ArrayListMultimap工作

Question

I'm relatively new to java, and am working on a new analysis method to improve my current implementation of ( https://stackoverflow.com/questions/26577172/inefficcient-optimally-deleting-2s-rows-and-columns-from-a-random-mod2 ).

I've determined that I want a multimap to process my dataset. Thus, I downloaded Guava and placed the ~2MB file into a directory. I compile my program using Multimap or ArrayListMultimap with:

javac -classpath C:\mywork\guava-18.0.jar myfile.java

Edit: At the advice of user2336315, I changed the code to:

ArrayListMultimap<String, int[]> combinations = ArrayListMultimap.create();

This compiles perfectly. However, I then get another error when I run the script with 'java Optimize':

To see how to run the code properly after compiling, please refer to the answer comments below.

Here's my current test code:

import java.util.Random;
import com.google.common.collect.ArrayListMultimap;    

class Determine {
    public static int[][] rando() {
        // Various lines of code to product a random matrix
    }
}

class Search {
    public static void finalize(int[][] a) {
        int bluejay =  a.length;
        int minimum = 1;

        ArrayListMultimap<String, int[]> combinations = ArrayListMultimap.create();
        for (int x = 0; x < bluejay - minimum + 1; x++) {
            int y = 0;
            while (y < 5) {
                int[] rows = new int[x + 1];
                rows[0] = 1;
                combinations.put(Integer.toString(x), rows);
                y += 1;                 
            }
            System.out.println(combinations);
        }
    }
}

public class Optimize {
    public static void main(String[] args) {
        int[][] matrix  = Determine.rando();
        Search.finalize(matrix);
    }
}

Answer 1

The constructors of the class are private, you cannot see them outside the class. You have to use the static method that creates the map.

ArrayListMultimap<String, int[]> combinations = ArrayListMultimap.create();

As for the second error, I don't see any Guava class with this name, so maybe you mispelled it?
