In this tutorial, we will learn about the Java PrintStream class and its print() and printf() methods with the help of examples to print output data.

The internal error state is set to true when the underlying output stream throws an IOException other than InterruptedIOException, and when the setError method is invoked. If an operation on the underlying output stream throws an InterruptedIOException, then the PrintStream converts the exception back into an interrupt by doing:

May 10, 2024 - PrintStream format(String for, Object… args): Used to write a formatted string to the output stream using the given format string and parameters. ... Return parameters: The output stream. Throws 2 kinds of exception IllegalFormatException and NullPointerException · Below is an example of Java PrintStream.

September 3, 2015 - The instantiation of the OutputStream ... out of the example for brevity. The PrintStream has a wide selection of constructors that enable you to connect it to a File, an OutputStream etc. You may be familiar with these two well-known PrintStream instances in Java: System.out and ...

Once we are done printing, we have to flush the PrintStream. import java.io.FileNotFoundException; import java.io.PrintStream; import java.time.LocalDate; public class FileWritingDemo { public static void main(String[] args) { String destination = "file1.txt"; try(PrintStream ps = new PrintStream(destination)){ ps.println("Stackoverflow documentation seems fun."); ps.println(); ps.println("I love Java!"); ps.printf("Today is: %1$tm/%1$td/%1$tY", LocalDate.now()); ps.flush(); } catch (FileNotFoundException e) { e.printStackTrace(); } } }

3 weeks ago - Optionally, a PrintStream can be created so as to flush automatically; this means that the flush method of the underlying output stream is automatically invoked after a byte array is written, one of the println methods is invoked, or a newline character or byte ('\n') is written.

The PrintStream class provides methods to write data to another stream. The PrintStream class automatically flushes the data so there is no need to call flush() method. Moreover, its methods doesn't throw IOException.

package com.tutorialspoint; import java.io.*; public class PrintStreamDemo { public static void main(String[] args) { String s = "Hello World"; // create printstream object PrintStream ps = new PrintStream(System.out); // print string ps.print(s); ps.print(" This is an example"); // flush the stream ps.flush(); } }
