我在名为PointCP2的文件中有一个名为design2的类，我有
package design;在我的课程PointCP2的顶部。在同一个文件中的测试类（PC2Test）中，我的顶部是import design2.*;，但是每次尝试运行该错误时，我都会不断收到此错误？
我该如何解决？
PointCP2Test.java:5: error: package design2 does not exist
import design2.*;
^
PointCP2Test.java:85: error: cannot access PointCP2
private static PointCP2 getInput() throws IOException
^
bad class file: ./PointCP2.class
class file contains wrong class: design2.PointCP2
Please remove or make sure it appears in the correct subdirectory of the classpath.
