我在 main 方法中执行如下：

int secrete = 42;
for (int i = 0; i < 5; i++) {
    Consumer<String> myprinter2 =
                    msg -> {
                        System.out.println("consuming " + msg + " ," + secrete);
                    };
     myprinter2.accept(myprinter2.toString());
}

上述代码的输出是：

int secrete = 42;
for (int i = 0; i < 5; i++) {
    Consumer<String> myprinter2 =
                    msg -> {
                        System.out.println("consuming " + msg + " ," + secrete);
                    };
     myprinter2.accept(myprinter2.toString());
}

如果我改为secretefinal，那么输出是：

consuming Main$$Lambda$1/1324119927@6d311334 ,42
consuming Main$$Lambda$1/1324119927@682a0b20 ,42
