Class FileOutput

java.lang.Object
  java.io.Writer
      java.io.PrintWriter
          gpdraw.FileOutput

All Implemented Interfaces:

java.io.Closeable, java.io.Flushable, java.lang.Appendable

public class FileOutput
extends java.io.PrintWriter

FileOutput provides simple methods for opening and writing to text files. This class implements most of the print methods found in PrintWriter.

Methods in this class never throw I/O exceptions. The client may inquire as to whether any errors have occurred by invoking checkError().

  Example:
  =======

  FileOutput outFile = new FileOutput("anyname.txt");
  outFile.print("2 + 2 = ");
  outFile.println(4);
  outFile.printf("e = %+10.4f", Math.E);    // -> "e =    +2.7183"
  outFile.println();                        // an extra blank line
  outFile.close();                          // optional
