java.util.Properties

The Properties class represents a persistent set of properties. The Properties can be saved to a stream or loaded from a stream. Each key and its corresponding value in the property list is a string.

Some more Methods of Properties class.

clear(): This method Clears this hashtable so that it contains no keys.

clone(): This method creates a shallow copy of this hashtable.

compute(Object, BiFunction): This method computes the values according to the mapping function.

computeIfAbsent(Object, Function): If the specified key is not already associated with a value attempt to compute its value using the given mapping function and enter it into this property unless null.

computeIfPresent(Object, BiFunction): If the value for the specified key is present and non-null, attempts to compute a new mapping given the key and its current mapped value.

contains(Object): This method tests if some keymaps into the specified value in this hashtable.

containsKey(Object): This method tests if the specified object is a key in this hashtable.

containsValue(Object): This method returns true if this hashtable maps one or more keys to this value.

elements(): This method returns an enumeration of the values in this hashtable.

entrySet(): This method returns a Set view of the mappings contained in this map.

equals(Object): This method compares the specified Object with this Map for equality.

forEach(BiConsumer): his method performs the given action for each entry in this map until all entries have been processed or the action throws an exception.

get(Object): This method returns the value to which the specified key is mapped, or null if this map contains no mapping for the key.

getOrDefault(Object, Object): This method returns the value to which the specified key is mapped, or defaultValue if this map contains no mapping for the key.

getProperty(String): This method searches for the property with the specified key in this property list.
