Why doesn't JDK read from within a package?

[jon80]

Code: Select all

package food;
class Dog
{

}
package food;
class Terrier extends Dog
{
	void walk()
	{
		System.out.println("Terrier walks");
	}
}

Error
C:\Documents and Settings\Jon\Desktop\food\Terrier.java:2: error: cannot find symbol
class Terrier extends Dog
^
symbol: class Dog
1 error

Tool completed with exit code 1 [/b]

How is your classpath configured? Does it contain . (dot = current directory)?

I found a solution.

file TestOne.java lies in a folder called one (otherwise, package one; would make no sense).

so to find the way from TestOne to one/Dog.java, the classpath needs to contain the folder containing folder one (either relatively referenced by .. or as absolute path)

you need to learn the syntax of the set command ('help set' should help you)


(and you need to learn the difference between comma and semicolon)
