File
Objects with Stream Constructors
Some constructors for IO streams that connect to disk files
use a File
object argument.
(Previously, examples used constructors with String arguments).
Here is a list of them:
FileInputStream(File file) throws IOException FileOutputStream(File file) throws IOException FileReader(File file) throws FileNotFoundException FileWriter(File file) throws FileNotFoundException
Here is some more of the file copy program, now with blanks to fill in the constructors:
import java.io.*; class CopyBytes { public static void main ( String[] args ) { DataInputStream instr; DataOutputStream outstr; . . . . File inFile = new File( args[0] ); File outFile = new File( args[2] ); . . . . try { instr = new DataInputStream( new BufferedInputStream( new FileInputStream( ____________ ))); outstr = new DataOutputStream( new BufferedOutputStream( new FileOutputStream( ____________ ))); . . . . } }
