Name Spaces, Packages or Units

Names Spaces (in C++), Packages (Java) or Units (Delphi and Object Pascal) give the programmer another way to encapsulate names, and release only those names that are necessary.
package foo;
	public class bar { // will be visible
		...
	}

	class baz { // will not be visible outside package
		...
	}
