Java 导入时找不到 package

Question

I have a file structure as follows:

src/cs/example/Hello.java
src/cs/utility/HelloHelp.java
bin/cs/example/Hello.class
bin/cs/utility/HelloHelp.class

The package and import statements in Hello.java are:

package cs.example;
import cs.utility.MyMethods;

While the package statement in HelloHelp is:

package cs.utility;

I attempt to run Hello (that uses a method from HelloHelp):

    java -cp src/cs/utility src/cs/example/Hello.java
src/cs/example/Hello.java:2: error: package cs.utility does not exist
import cs.utility.HelloHelp;
                     ^
src/cs/example/Hello.java:10: error: cannot find symbol
        int max = HelloHelp.borp(intOne,intTwo);
                  ^
  symbol:   variable HelloHelp
  location: class Hello

Any help on resolving this issue would be very useful, thank you!

Answer 1

In your java -cp call you are pointing to your .java files instead of your .class files in /bin .

Try changing your java command to use the class files instead. Something like the following should work:

java -cp "bin/*" cs.example.Hello
