IntelliJ IDEA中Lambda表达式警告:Can be replaced with method reference less

Can be replaced with method reference less… (Ctrl+F1) This
inspection reports lambdas which can be replaced with method
references Lambda/method references syntax is not supported under Java
1.7 or earlier JVMs.

代码如下

    @Test
    public void test() {
        ArrayList strings = new ArrayList<>();
        strings.add("1");
        strings.add("2");
        strings.add("3");
        strings.add("4");
        strings.forEach((String str)-> System.out.println(str));
    }

应该把爆警告的那句话修改成

strings.forEach(System.out::println);

无警告多清爽！
