Java Generics – 插入内部类型参数

我是 java的新手.我只是想传递Comparable< String>进入泛型类型的方法参数< E extends Comparable< E>> .我相信< E的含义扩展了Comparable< E>>是任何扩展Comparable的对象.请告诉我如何传递Comparable< String>或任何扩展Comparable< String>的对象并且还有另一个对象.

编译器给我错误推断类型比较< String>不是有界参数的有效替代< E extends Comparable< E>>

码：

public class Compare<T> implements Comparable<T>{

    public int compareTo(T o) {

        return 0; // Not worried about logic

    }

}

class CompareTest{

    public <E extends Comparable<E>>void testGeneric(E e){

        System.out.println("Executed");
    }

    public static void main(String args[]){
        Compare<String> compare = new Compare<String>();

        CompareTest test = new CompareTest();
        test.testGeneric(compare);
        //The inferred type Compare<String> is not a valid substitute for the bounded
        //parameter <E extends Comparable<E>>
    }
}

public class Compare<T> implements Comparable<T>
