The java.util.TreeMap.containsValue() method is used to check whether a particular value is being mapped by any key in the TreeMap. It takes the Value as a parameter and returns True if that value is mapped by any of the keys in the map.
Parameters: The method takes just one parameter Value of Object type and refers to the value whose mapping is supposed to be checked by any key inside the map.
Return Value: The method returns boolean true if the mapping of the value is detected else false.
Below programs are used to illustrate the working of java.util.TreeMap.containsValue() Method:
Program 1: Mapping String Values to Integer Keys.
Program 2: Mapping Integer Values to String Keys.
Note: The same operation can be performed with any type of Mappings with variation and combination of different data types.
