打比方一个类里边有多个内部类，怎样获取该类里边指定的某一个内部类

public class FactoryTest {

@Testpublicvoidtest2(){ FactoryTest factoryTest =newFactoryTest(); Class clazz = factoryTest.getClass(); Class[] classes = clazz.getDeclaredClasses(); System.out.println(Arrays.toString(classes));//只能获取一个数组

结果：[class com.design.factory.FactoryTest$Triangle, classcom.design.factory.FactoryTest$Square, class com.design.factory.FactoryTest$Circle, interface com.design.factory.FactoryTest$Shape]

}

interfaceShape{publicabstractvoiddraw();}classCircleimplementsShape{publicvoiddraw(){ System.out.println("draw Circle"); }}classSquareimplementsShape{publicvoiddraw(){ System.out.println("draw Square"); }}classTriangleimplementsShape{publicvoiddraw(){ System.out.println("draw Triangle"); }}

}
