The Java.util.EnumMap.get(Object key) method in Java is used to give the mapped value of the specified key. Syntax:

get(Object key)

Parameter: The method takes one parameter key which is passed to return the value associated with it. Return Value: It returns the value mapped with the associated key. Below programs illustrate the working of get() function: Program 1:

Java

// Java program to demonstrate get(key)
import java.util.*;

// An enum of geeksforgeeks
public enum gfg {
    Global,
    India
}
;

class Enum_demo {
    public static void main(String[] args)
    {

        EnumMap<gfg, Integer> mp = new 
                     EnumMap<gfg, Integer>(gfg.class);

        // Values are associated
        mp.put(gfg.Global, 800);
        mp.put(gfg.India, 72);

        // Stores the value mapped with the key specified
        int res = mp.get(gfg.India);

        // Prints the result
        System.out.println("GeeksforGeeks ranked in India: " 
                                                    + res);
    }
}

Output:

GeeksforGeeks ranked in India: 72

Program 2:

Java

// Java program to demonstrate get(key)
import java.util.*;

// An enum of geeksforgeeks
public enum gfg {
    India,
    United_States,
    China
}
;

class Enum_demo {
    public static void main(String[] args)
    {

        EnumMap<gfg, String> mp = new 
                  EnumMap<gfg, String>(gfg.class);

        // Values are associated
        mp.put(gfg.India, "61.7%");
        mp.put(gfg.United_States, "18.2%");
        mp.put(gfg.China, "2.5%");

        // Stores the value mapped with the key specified
        String res = mp.get(gfg.United_States);

        // Prints the result
        System.out.println("Visitors in United_States: " 
                                                   + res);
    }
}

Output:

Visitors in United_States: 18.2%
