the import cannot be resolved
遇到一些错:全部都类似于
1.Java的基础API包 The import java.util cannot be solved.
2.项目已经开发好的包 The import com.thu.thunet.thu_core cannot be solved.
开发工具是德国一家公司在Eclipse基础上开发的,类似于MyEclipse.
现在我想知道的是,
1.) import某个包是直接导入原代码包(java package),还是导入jar包.
2.) 如果新建一个包,编译不过,是不是只会产生编得过的类class文件,而不会产生整个项目包的jar包.
1.) import是导入jar包,即.class文件库.import 为调用 (引用) 编译好的.class(字节码)文件.
2.) 如果新建一个包,编译不过,是不是只会产生编得过的类class文件,而不会产生整个项目包的jar包.对.
