Program: How to add all elements of a list to LinkedList?


Description:

Here we can see example for copying another collection instance objects to existing LinkedList.


Code:
package com.java2novice.linkedlist;

import java.util.ArrayList;
import java.util.LinkedList;
import java.util.List;

public class MyLinkedListNewCollection {

	public static void main(String a[]){
		
		LinkedList<String> arrl = new LinkedList<String>();
		//adding elements to the end
		arrl.add("First");
		arrl.add("Second");
		arrl.add("Third");
		arrl.add("Random");
		System.out.println("Actual LinkedList:"+arrl);
		List<String> list = new ArrayList<String>();
		list.add("one");
		list.add("two");
		arrl.addAll(list);
		System.out.println("After Copy: "+arrl);
	}
}

Output:
Actual LinkedList:[First, Second, Third, Random]
After Copy: [First, Second, Third, Random, one, two]

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){

}
}
}
