Properties class Methods in Java Part -I

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.
