LinkedHashMap Class get() method

  • get() method is available in java.util package.
  • get() method is used to get the associated value for the given key element (key_ele).
  • get() method is a non-static method, it is accessible with the class object only 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 value element.

Syntax:

    public Value get(Object key_ele);

Parameter(s):

  • Object key_ele – represents the key element whose associated value element is to be retrieved.

Return value:

The return type of the method is Value, it returns the associated value for the given key element (key_ele) otherwise it returns null.

Example:

// Java program to demonstrate the example 
// of Value get(Object key_ele)  method 
// of  LinkedHashMap 

import java.util.*;

public class GetOfLinkedHashMap {
    public static void main(String[] args) {
        // Instantiates a LinkedHashMap object
        Map < Integer, String > map = new LinkedHashMap < Integer, String > ();

        // By using put() method is to add
        // key-value pairs in a LinkedHashMap
        map.put(10, "C");
        map.put(20, "C++");
        map.put(50, "JAVA");
        map.put(40, "PHP");
        map.put(30, "SFDC");

        // Display LinkedHashMap
        System.out.println("LinkedHashMap: " + map);

        // By using get() method is to return
        // the value associated for the given
        // key element exists in this LinkedHashMap

        Object val_ele = map.get(50);

        //Display val_ele
        System.out.print("map.get(50): ");
        System.out.println(val_ele);
    }
}

Output

LinkedHashMap: {10=C, 20=C++, 50=JAVA, 40=PHP, 30=SFDC}
map.get(50): JAVA
