Fetch key-valuepair from Java LinkedHashSet
To fetch LinkedHashSet key-value pair in Java, use the entrySet() method.
Let us first create LinkedHashSet 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, fetch a key-value pair −
l.entrySet()
The following is an example to fetch key-value pair from LinkedHashSet −
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...");
System.out.println("Key Value pair = "+l.entrySet());
}
}Output
LinkedHashMap elements... Key Value pair = [1=Jack, 2=Tom, 3=Jimmy, 4=Morgan, 5=Tim, 6=Brad]
