Lambda表达式的遍历

        List <String>list=new ArrayList<>(Arrays.asList("a","b","c","d"));

		System.out.println("超级for循环方式");
		for(String str:list){
			System.out.println(str);
		}
		
		System.out.println("匿名内部类方式");
		list.forEach(new Consumer<String>() {
			@Override
			public void accept(String t) {
				System.out.println(t);
				System.out.println(t.getClass());
			}
		
		});
		
		System.out.println("匿名内部类结合Lambda表达式");  		
		list.forEach(str->{System.out.println(str+"哈哈");});
