Java泛型:获取泛型方法的返回类型

import java.lang.reflect.Method;

public class GenericMethodExample {
    public static <T> T genericMethod(T value) {
        return value;
    }

    public static void main(String[] args) throws NoSuchMethodException {
        Method method = GenericMethodExample.class.getMethod("genericMethod", Object.class);
        System.out.println("Return type of genericMethod: " + method.getReturnType());
    }
}

Return type of genericMethod: class java.lang.Object

import java.lang.reflect.Method;

public class GenericMethodExample {
    public static <T> T genericMethod(T value) {
        return value;
    }

    public static void main(String[] args) throws NoSuchMethodException {
        Method method = GenericMethodExample.class.getMethod("genericMethod", String.class);
        System.out.println("Return type of genericMethod with String argument: " + method.getReturnType());
    }
}

Return type of genericMethod with String argument: class java.lang.String
