### Question:
PropertyParser { public int toInt(String name) { return toInt(name, 0); } PropertyParser(Properties properties); Properties getProperties(); void setProperties(Properties properties); String parseString(String name); int parseInt(String name); boolean parseBoolean(String name); float parseFloat(String name); double parseDouble(String name); long parseLong(String name); char parseChar(String name); String toString(String name); int toInt(String name); boolean toBoolean(String name); float toFloat(String name); double toDouble(String name); long toLong(String name); char toChar(String name); String toString(String name, String defaultValue); int toInt(String name, int defaultValue); boolean toBoolean(String name, boolean defaultValue); float toFloat(String name, float defaultValue); double toDouble(String name, double defaultValue); long toLong(String name, long defaultValue); char toChar(String name, char defaultValue);  }### Answer:
