How to use getMethod() with primitive types?
提问by yegor256
This is the class:
这是课程：
class Foo {
public void bar(int a, Object b) {
}
}
Now I'm trying to get "reflect" this method from the class:
现在我试图从类中“反射”这个方法：
Class c = Foo.class;
Class[] types = { ... }; // what should be here?
Method m = c.getMethod("bar", types);

There's just an int.class.
只有一个int.class.
Class[] types = { int.class, Object.class };
An alternative is Integer.TYPE.
另一种选择是Integer.TYPE。
Class[] types = { Integer.TYPE, Object.class };
The same applies on other primitives.
这同样适用于其他原语。

The parameter of the method is a primitive shortnot an Object Short.
该方法的参数是一个原语short而不是一个 Object Short。
Reflection will not find the method because you specified an object short. The parameters in getMethod()have to match exactly.
反射将找不到该方法，因为您指定了一个短对象。中的参数getMethod()必须完全匹配。
EDIT: The question was changed. Initially, the question was to find a method that takes a single primitive short.
编辑：问题已更改。最初，问题是要找到一种方法，该方法采用单个原语短路。
