List中使用foreach

import java.util.Arrays;
import java.util.Collections;
import java.util.List;

public class InListUsingForeach {

public static void main(String[] args) {
    // TODO Auto-generated method stub
    // Get and shuffle the list of arguments
    List<String> argList = Arrays.asList(args);
    Collections.shuffle(argList);

    // Print out the elements using JDK 8 Streams
    argList.stream()
    .forEach(e->System.out.format("%s ",e));

    // Print out the elements using for-each
    for (String arg: argList) {
        System.out.format("%s ", arg);
    }

    System.out.println();
}

}
使用了Lambda表达式...
