Java Utililty Methods Properties to Map

Map<String, String> result = new HashMap<String, String>(properties.size());
for (Map.Entry<Object, Object> parameter : properties.entrySet()) {
    String value = null;
    if (parameter.getValue() != null) {
        value = parameter.getValue().toString();
    result.put(parameter.getKey().toString(), value);
return result;

Map<String, String> result = new HashMap<String, String>(properties.size());
for (String key : properties.stringPropertyNames()) {
    result.put(key, properties.getProperty(key));
return result;

return new HashMap(props);

return props == null ? new HashMap<String, String>() : new HashMap<String, String>((Map) props);

HashMap<String, V> result = new HashMap<>();
for (String name : props.stringPropertyNames()) {
    result.put(name, (V) props.getProperty(name));
return result;

Set<String> names = props.stringPropertyNames();
HashMap<String, Object> map = new HashMap<String, Object>(names.size());
for (String name : names) {
    map.put(name, props.getProperty(name));
return map;

Map<String, String> map = new HashMap<>();
for (String key : props.stringPropertyNames()) {
    if (key.startsWith(prefix)) {
        map.put(key.substring(prefix.length()), props.getProperty(key));
return map;

if (sourceProperties == null) {
    return null;
Map<String, String> configMap = new HashMap<String, String>();
Iterator<?> iter = sourceProperties.keySet().iterator();
while (iter.hasNext()) {
    String key = (String) iter.next();
    configMap.put(key, sourceProperties.getProperty(key));
