### Question:
PropertiesConfiguration extends EventSource { private String getProperty(String key) { return store.get(key); } PropertiesConfiguration();  PropertiesConfiguration(final String projCode);  PropertiesConfiguration(final String projCode, final String profile);  PropertiesConfiguration(final String projCode, final String profile, final String modules);  PropertiesConfiguration(final String projCode, final String profile, String modules, String localFilePath);  PropertiesConfiguration(String host, int port, final String projCode, final String profile);  PropertiesConfiguration(String host, int port, final String projCode, final String profile, final String modules);  PropertiesConfiguration(String host, int port, final String projCode,
                                   final String profile, String modules,
                                   String localFilePath); void close(); void load(String config); void load(Reader in, boolean reload); static String getHost(); static int getPort(); static String getProjCode(); static String getProfile(); static String getModules(); static String getLocalFilePath(); Properties getProperties(); boolean getBoolean(String key); boolean getBoolean(String key, boolean defaultValue); Boolean getBoolean(String key, Boolean defaultValue); byte getByte(String key); byte getByte(String key, byte defaultValue); Byte getByte(String key, Byte defaultValue); double getDouble(String key); double getDouble(String key, double defaultValue); Double getDouble(String key, Double defaultValue); float getFloat(String key); float getFloat(String key, float defaultValue); Float getFloat(String key, Float defaultValue); int getInt(String key); int getInt(String key, int defaultValue); Integer getInteger(String key, Integer defaultValue); long getLong(String key); long getLong(String key, long defaultValue); Long getLong(String key, Long defaultValue); short getShort(String key); short getShort(String key, short defaultValue); Short getShort(String key, Short defaultValue); String getString(String key); String getString(String key, String defaultValue);  }### Answer:
@Test public void testSysProperties1() throws ConfigurationRuntimeException { String str = System.getProperty("java.version1"); System.out.print(str); }
