Java i JUnit, Нуждая се от помощ за Java и JUnit

това звучи като виц за анален секс

Благодаря за бързите отговори, но все още не съм сигурен как да направя едно нещо.
След като си свалих допълнителния изходен код, все още не мога да го използвам, пиша това, което ми пише в "Read me"-файла, обаче пак ми дава грешка.. Вече не знам къде бъркам. Ще постна цялото описание:"
Compiling the Classes

The production classes are self-contained -- they don't have any dependencies on external class libraries etc. So, to compile the production classes for Chapter 3 -- Lists -- enter the following command:

javac -sourcepath main main/com/wrox/algorithms/lists/*.java

This invokes the compiler telling it to compile all production files in the com.wrox.algorithms.lists package.

Notice the the -sourcepath main option. This tells the compiler where to look for any other files it may need. For example, in this case, the code for Chapter 3 depends on the code for Chapter 2 -- Iteration and Recursion -- so the compiler needs to know where to look to find the dependent source files.

Compiling the test classes is similar except for one thing: they depend on JUnit. So, in order to compile the test classes, you will first need to download a copy of JUnit from here and extract the junit.jar file. Once this is done, you can compile the test classes for Chapter 3 by entering the following command:

javac -classpath junit.jar -sourcepath main test/com/wrox/algorithms/lists/*.java

This invokes the compiler telling it to compile all test files in the com.wrox.algorithms.lists package2.

Once again, notice the extra -sourcepath main option telling the compiler where to look for any other files it may need."
Ако някой има идея нека да сподели, моля!
