GIGO: words unreadable aloud

Chapter 5, Exercises 1-2

1. Write a program that creates an ArrayList object without explicitly importing java.util.*.

object c5x1 {
    def main ( args: Array[String] ) = {
        var ar : java.util.ArrayList = _;
    }
}

2. In the section labeled "package: the library unit", turn the code fragments concerning mypackage into a compiling and running set of Java files.

Well, s/Java/Scala/...

Choice (a) is simply to refer to MyClass with a qualified reference:

c5x2a.scala:

package x;
object c5x2a {
    def main ( args: Array[String] ) = {
        var m = new mypackage.MyClass();
    }
}

Choice (b) is to import MyClass from its package:

c5x2b.scala:

package x;
import mypackage._;
object c5x2b {
    def main ( args: Array[String] ) = {
        var m = new MyClass();
    }
}

Both of them refer to

c5x2z.scala:

package mypackage;
class MyClass { }
