Method

StringgetProperty(Properties props, String propname)
Check first for a particular property in the System Properties, so that the -Dprop="value" command line arg mechanism can be used to override values defined in the passed in property file. 
return getProperty(props, propname, null);
StringgetProperty(String[] system_props, Properties props, String prop_name, boolean ignore_sysprops, String default_value)
Returns a value associated wither with one or more system properties, or found in the props map 
String retval = null;
if (props != null && prop_name != null) {
    retval = props.getProperty(prop_name);
    props.remove(prop_name);
if (!ignore_sysprops) {
    String tmp, prop;
    if (system_props != null) {
...
doublegetPropertyDouble(Properties p, String key)
convert a properties value into an int 
Object test = p.get(key);
if (test == null)
    return (Double.MIN_VALUE);
return (Double.parseDouble(test.toString()));
LonggetPropertyLong(Properties properties, String context, String key, Long def)
Delegates to #getProperty(Properties,String,String,String) but returns the value as an Long where Long#valueOf(String) defines the actual value 
return Long.valueOf(getProperty(properties, context, key, def == null ? null : def.toString()));
StringgetPropertyString(Properties properties, String propertyName)
get Property String 
String value = "";
value = properties.getProperty(propertyName);
if (value == null) {
    return "";
;
return value;
StringgetPropertyText(String property, Object... replacements)
get Property Text 
String message;
if (APPLICATION_RESOURCES.containsKey(property)) {
    message = APPLICATION_RESOURCES.getString(property);
} else {
    message = RESOURCES.getString(property);
if (message.contains("'") && !message.contains("''")) {
    message = message.replaceAll("(.)'(.)", "$1''$2");
...
StringgetPropertyValue(Properties props, String key)
get Property Value 
return getPropertyValue(props, key, EMPTY_STRING);
intgetPropertyValueAsInt(Properties props, String key, int defaultValue)
Get integer value from given properties. 
return props == null || !props.containsKey(key) ? defaultValue : Integer.parseInt(props.getProperty(key));
StringgetRefValue(Properties result, String v)
get Ref Value 
while (v != null && v.startsWith(REF)) {
    String ref = v.substring(1);
    v = result.getProperty(ref);
    if (v == null) {
        v = System.getProperty(ref);
return v == null ? "" : v;
...
PropertiesgetSection(Properties props, String sectionName, boolean removeSectionName)
get Section 
Properties ret = new Properties();
for (Enumeration<?> e = props.propertyNames(); e.hasMoreElements();) {
    String key = (String) (e.nextElement());
    if (key.startsWith(sectionName + ".")) {
        String newkey = removeSectionName ? key.substring(sectionName.length() + 1) : key;
        ret.setProperty(newkey, props.getProperty(key));
    } else if (key.equals(sectionName) && !removeSectionName) {
        ret.setProperty(key, props.getProperty(key));
