问大语言模型比在这里提问会来的更快
大语言模型说
1. findSpecial 用来调用 private 方法,但是 getSum 不是 private 方法
2. findSpecial 中 getSum 的参数数量与实际不符
3. LambdaMetafactory 中也是参数不符
```
@
Testpublic void likeReflectTest() throws Throwable {
Class<MethodHandles.Lookup> lookupClass = MethodHandles.Lookup.class;
Field implLookup = lookupClass.getDeclaredField("IMPL_LOOKUP");
implLookup.setAccessible(true);
MethodHandles.Lookup lookup = (MethodHandles.Lookup)implLookup.get(null);
// Assuming getSum is private, otherwise findVirtual should be used.
MethodHandle getSum = lookup
.in(Phone.class)
.findSpecial(
Phone.class,
"getSum",
methodType(int.class, int.class, int.class),
Phone.class
);
CallSite applyAsInt = LambdaMetafactory.metafactory(
lookup,
"applyAsInt",
methodType(ToIntFunction2.class),
methodType(int.class, Phone.class, int.class, int.class), // This should match the interface's method signature.
getSum,
getSum.type() // This should be the method handle's type.
);
ToIntFunction2 func = (ToIntFunction2) applyAsInt.getTarget().invoke();
int intResult = func.applyAsInt(new Phone(), 1, 0);
System.out.println(intResult);
}
```
