File.java: Import needed classes instead of whole packages...

2003-03-28  Michael Koch  <konqueror@gmx.de>

	* java/io/File.java:
	Import needed classes instead of whole packages, merged class
	documentation with classpath, moved constants and variables to top of
	class.
	* java/io/PrintStream.java:
	Merged class documentation with classpath, moved constants and
	variables to top of class.
	* java/io/RandomAccessFile.java
	(RandomAccessFile): Merged with classpath.
	(read): Merged with classpath).
	(read*): Reformatted.
