public class main {
    public static void main(String args[]){
        Arrays arrs = (message, message2) -> System.out.println(message + message2);
        arrs.print("hello"," world!");
    }
    interfaceArrays {
        voidprint(String message, String message2);
    }
}

新建一个接口，提供"抽象"的print功能传递message和message2,调用arrs的print功能并传递两个字符串,执行arrs后返回结果:

hello world!
