Получение ошибки при выполнении java-программ пакетов из командной строки

Я выполняю программы из командной строки и использую пакеты в них. имена моих программных файлов — TestA.java и TestB.java.

Я выполнил ниже изначально javac TestA.java

Нет проблем для вышеупомянутого, и он сгенерировал файл класса также для следующего, я наблюдаю проблему javac TestB.java

TestB.java:2: error: '.' expected import TestA; ^ TestB.java:2: error: ';' expected import TestA; ^ 2 errors 

package a.b; class TestA < public static void methodPublic()< methodPrivate(); >protected static void methodProtected() < methodPrivate(); >static void methodDefault() < methodPrivate(); >private static void methodPrivate()<> >

Я выполняю javac, перейдя в папку b, где существуют эти два файла.

Я выполняю javac, перейдя в папку b, где существуют эти два файла.

Вы не хотите этого делать; полное имя класса каждого класса включает в себя пакет. Они образуют дерево. Очень похоже на вашу файловую систему. Из b папка переместиться вверх на две директории (в папку, содержащую a — например cd ../.. или же cd ..\.. на винде). затем

javac -cp . a/b/TestA.java a/b/TestB.java 

Кроме того, вы обычно хотите, чтобы это было записано в «двоичную» выходную папку. Так

javac -cp . -d bin a/b/TestA.java a/b/TestB.java 

Наконец, вам не нужно import TestA потому что он находится в той же упаковке, что и TestB , Но, если вы хотите, вам нужно

Ошибка Java ‘;’ ожидаемый, не могу найти проблему

u180921.java:2 -> 2 — это номер строки. Обычно при ошибках компиляции вы также получаете подсказку по номеру строки. Большинство IDE, таких как Eclipse и Intellij, также позволяют напрямую переходить к этой строке.

u180921.java:2 означает вторую строку u180921.java , а сообщение после error: говорит о том, что не так.

Что такое acc (i)? Предполагается, что это arr [i]? acc (i) — это вызов функции, вы не можете ничего назначить функции. Кроме того, вы не определили scc в своем коде.

JavaC compilation error: ‘.’ expected

I am trying to find a reference to this error somewhere, but you can
imagine how difficult it is for a search engine to actually find ‘.’
verbatim, assuming that the first quote, the period, or the second
quote can be ignored.

In any case, I was compiling my java classes and I’m getting this odd
error, not knowing how to fix it:

com.thing.etc.etc. ‘.’ expected
import classIwasImporting

Where can I find out about this error, and how can I fix it? First of
all, can someone give me a reference to a specific place where I can
at least figure out what this error means, or if anyone has any
insight on what the compiler is thinking when it comes up with this
error, I’d appreciate it.

I would assume that it’s because you’re importing something
incorrectly.

Can you give me an example?

That’s incorrect, should either import a specific class.

com.net.URL; or the whole thing ‘com.net.*’

Klauer

The class I’m importing is a specific class. This specific .class is
in the classpath, and this used to compile before(in IntelliJ). We
are moving our Ant scripts to be platform independent, and have come
across an error like this preventing it from happening. We are also
compiling this under JDK 1.3, if that helps any.

For instance, the class is a pre-compiled class crSampleClass.

All of our source for many of these files simply

public class crExtSampleClassExtension
.
>

and this compiles correctly and creates a functional .jar that we use
in production. I’m just curious why this wouldn’t be working now, and
coming up with an error like this in it.

What’s your package structure look like? If you could give me a better
idea of what package the file you can’t compile is in, and what the
import statement looks like, when compared to the root directory I
could probably help more.

Klauer

Well, I’ll try my best to describe the package structure.

We have a set of pre-compiled .class files that sit on a client and
server of our software on the hard drive. These supporting .class
files are generated by that program itself, and we pull reference and
import these directly from those physical locations. They do fall
under a package, as defined in their .java, but physically—on the
hard drive—they sit in a random directory, e.g. client/module1/
runtime/classes.

With the way we had it working before, this is an example of what most
of the extending java modules would look like:

the crClass.class actually belongs to the same
com.company.name.package.one package, as it was defined pre-
compilation, so importing while in that same package worked just
fine. What I don’t get is why I’m seeing this error now, as IntelliJ
compiled the source down to .classes and .jars without as much as a
whimper.
