Program: How to compare two LinkedHashSet and retain elements which are same on both LinkedHashSet?


Description:

Below example shows how to compare two LinkedHashSet and retain elements which are same on both LinkedHashSet


Code:
package com.java2novice.linkedhashset;

import java.util.LinkedHashSet;

public class MyLhsRetainEx {

	public static void main(String a[]){
		
		LinkedHashSet<String> lhs = new LinkedHashSet<String>();
		//add elements to LinkedHashSet
		lhs.add("first");
		lhs.add("second");
		lhs.add("third");
		lhs.add("apple");
		lhs.add("rat");
		System.out.println(lhs);
		LinkedHashSet<String> subSet = new LinkedHashSet<String>();
		subSet.add("rat");
		subSet.add("second");
		subSet.add("first");
		lhs.retainAll(subSet);
		System.out.println("LinkedHashSet content:");
		System.out.println(lhs);
	}
}

Output:
[first, second, third, apple, rat]
LinkedHashSet content:
[first, second, rat]

What is java static import?
By using static imports, we can import the static members from a class rather than the classes from a given package. For example, Thread class has static sleep method, below example gives an idea:

import static java.lang.Thread;
public class MyStaticImportTest {
public static void main(String[] a) {
try{
sleep(100);
} catch(Exception ex){

}
}
}
