Remove a value from Java LinkedHashMap
Use the remove() method to remove a single value from LinkedHashMap −
At first, create a LinkedHashMap and add some elements −
LinkedHashMap<String,String> l = new LinkedHashMap<String,String>(); l.put("1", "Jack"); l.put("2", "Tom"); l.put("3", "Jimmy"); l.put("4", "Morgan"); l.put("5", "Tim"); l.put("6", "Brad");
Now, let’s say you need to remove the element 2 from the LinkedHashMap. For that, use the remove() method −
Object ob = l.remove("2");
The following is an example to remove a value from LinkedHashMap in Java −
Example
import java.util.*; public class Demo { public static void main(String[] args) { LinkedHashMap<String,String> l = new LinkedHashMap<String,String>(); l.put("1", "Jack"); l.put("2", "Tom"); l.put("3", "Jimmy"); l.put("4", "Morgan"); l.put("5", "Tim"); l.put("6", "Brad"); System.out.println("LinkedHashMap elements...
"+l); // Remove an element Object ob = l.remove("2"); System.out.println("
LinkedHashMap elements after removing an element...
"+l); } }
Output
LinkedHashMap elements... {1=Jack, 2=Tom, 3=Jimmy, 4=Morgan, 5=Tim, 6=Brad} LinkedHashMap elements after removing an element... {1=Jack, 3=Jimmy, 4=Morgan, 5=Tim, 6=Brad}
