java.io.PrintWriter (class) |
Constructors: |
PrintWriter(Writer o);
PrintWriter(Writer o, boolean autoFlush);
PrintWriter(OutputStream o);
PrintWriter(OutputStream o, boolean autoFlush);
|
General Description: |
This class does some translation from data-types into readable text. The autoFlush flag forces a flush on when the program calls println(). |
Parent Class: |
Writer |
Methods |
boolean checkError(); |
Flush stream and check for any errors. |
void close(); |
Close this channel. |
void defaultWriteObject(); |
Write the current class' non-static and non-transient fields to this stream. You can only call this while in the writeObject() method during serialization. |
int flush(); |
Flush written data from buffers. |
int reset(); |
Toss the information written to the stream. |
void write(byte b); |
|
int write(byte[] arr); |
int write(byte[] arr, int |
offset, int len); |
Write a byte or an array of bytes beginning at offset for len bytes. |
void print(boolean b); |
|
void print(char c); |
|
void print(char[] s); |
|
void print(double d); |
|
void print(float f); |
|
void print(int i); |
|
void print(long l); |
|
void print(Object obj); |
|
void print(String s); |
Print the designated type. The Object type uses the String.valueOf() method to convert data. |
void println(); |
|
void println(boolean b); |
|
void println(char c); |
|
void println(char[] s); |
|
void println(double d); |
|
void println(float f); |
|
void println(int i); |
|
void println(long l); |
|
void println(Object obj); |
|
void println(String s); |
Print the designated type and terminate line with newline. If autoFlush is enabled, flush the stream. |
void write(int b); |
Write a single byte to the stream. |
int write(char[] arr); |
Write an array of char (arr) to stream.int write(char[] arr, int |
offset, int len); |
Write an array of char (arr) beginning at offset for len bytes. |
int write(String s); |
Write string to stream.int write(String s, int |
offset, int len); |
Write string to stream beginning at offset for len bytes. |
