Get Size of Java LinkedHashMap
The size() method is used to get the size of LinkedHashMap in Java.
Create a LinkedHashMap and add some elements to it −
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");Get the size now −
l.size()
The following is an example to get the size of LinkedHashMap −
Example
import java.util.LinkedHashMap;
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);
System.out.println("Size = "+l.size());
}
}Output
LinkedHashMap elements: {1=Jack, 2=Tom, 3=Jimmy, 4=Morgan, 5=Tim, 6=Brad}
Size = 6
