Split a String at every 3rd comma in Java

Question

I have a string that looks like this:

0,0,1,2,4,5,3,4,6

What I want returned is a String[]

Answer 1

Try something like the below:

public String[] mySplitIntoThree(String str) 
{
    String[] parts = str.split(",");

    List strList = new ArrayList();

    for(int x = 0; x < parts.length - 2; x = x+3) 
    {
        String tmpStr = parts[x] + "," + parts[x+1] + "," + parts[x+2];

        strList.add(tmpStr);
    }

    return strList.toArray(new String[strList.size()]);
}

(You may need to import java.util.ArrayList and java.util.List)
