"While digging through some database code in our system," Paul L wrote in, "I noticed an interesting pattern emerge. Whenever a boolean value within a SQL result was checked, it would look something like this..."

if (result != null && result.toUpperCase.equals(OurBoolean.TRUE))

"And although OurBoolean lacks a FILE_NOT_FOUND parameter, it does optimize for performance and memory usage through lazy list initialization."

package com.initrodeglobal.db.utils;

import java.util.List;
import java.util.ArrayList;

public class OurBoolean {

    public static final String TRUE = "TRUE";
    public static final String FALSE = "FALSE";

    private static List list = null;

    public static List getList() {
        if(list == null) {
            list = new ArrayList();
        return list;
