Utility methods for Java I don't want to think about ever again...

Util.java

/**
 * Simulates javascript's .join function.
 */
public static String combine(String glue, String... stringsToCombine) {
    int arryLength = stringsToCombine.length;
    if (arryLength == 0) {
        return null;
    }
    
    StringBuilder out = new StringBuilder();
    out.append(stringsToCombine[0]);
    for (int x=1; x < arryLength; ++x) {
        out.append(glue).append(stringsToCombine[x]);
    }
    
    return out.toString();
}
