would you please explain how to put classes in package and to use them.
I make a directory name One. And two classes: Class1 and Class2 in the
directory, One.

Class1.java:7: cannot find symbol
symbol  : class Class2
location: class One.Class1
               Class2 test = new Class2();
               ^
Class1.java:7: cannot find symbol
symbol  : class Class2
location: class One.Class1
               Class2 test = new Class2();
                                 ^
2 errors
Class2 compiled ok, but not Class1. The following is error while compiling
Class 1.

Class1.java:7: cannot find symbol
symbol  : class Class2
location: class One.Class1
               Class2 test = new Class2();
               ^
Class1.java:7: cannot find symbol
symbol  : class Class2
location: class One.Class1
               Class2 test = new Class2();
                                 ^
