Dictionary Class get() method

• get() method is available in java.util package.
• get() method is used to get the value on the specified key element (key_ele) in this dictionary.
• get() method is a non-static method, it is accessible with the class object and if we try to access the method with the class name then we will get an error.
• get() method does not throw an exception at the time of returning the value of the given key.

Syntax:

    public abstract Value get(Object key_ele);

Parameter(s):

• Object key_ele – represents key element (key_ele) and sets null when key element does not have value.

Return value:

The return type of this method is Value, it gets value on the given key element (key_ele) in this dictionary.

Example:

// Java program is to demonstrate the example
// of get() method of Dictionary

import java.util.*;

public class GetOfDictionary {
    public static void main(String[] args) {
        // Instantiate a Hashtable object
        Dictionary dictionary = new Hashtable();

        // By using put() method is to
        // add an elements in Hashtable 
        dictionary.put(1, "C");
        dictionary.put(2, "C++");
        dictionary.put(3, "JAVA");
        dictionary.put(4, "PHP");
        dictionary.put(5, "SFDC");

        // Display Hashtable elements
        System.out.println("dictionary: " + dictionary);

        // By using get() method is to return
        // the value associated for the given
        // key element (key_ele) if exists
        Object val_ele = dictionary.get(3);

        // Display val_ele
        System.out.println("dictionary.get(3): " + val_ele);
    }
}

Output

dictionary: {5=SFDC, 4=PHP, 3=JAVA, 2=C++, 1=C}
dictionary.get(3): JAVA
