PrintWriter PrintWriter(String, Charset) in Java

PrintWriter(String, Charset): This method is available in the java.io.PrintWriter class of java.

Syntax:

java.io.PrintWriter.PrintWriter(String fileName, Charset charset) throws IOException

This method takes two arguments. This method creates a new PrintWriter, without automatic line flushing, with the specified file name and charset.

Parameters: Two parameters are required for this method.

fileName: The name of the file to use as the destination of this writer. If the file exists then it will be truncated to zero sizes; otherwise, a new file will be created. The output will be written to the file and buffered.

charset: A charset

Throws:

1. IOException - if an I/O error occurs while opening or creating the file

2. SecurityException - If a security manager is present and checkWrite(fileName) denies write access to the file.

Approach

Java

import java.io.IOException;
import java.io.PrintWriter;
import java.nio.charset.Charset;

public class PrintWriterPrintWriter8 {
    public static void main(String[] args) throws IOException {

        String fileName = "D:\\hello.txt";
        Charset charset = Charset.defaultCharset();

        PrintWriter printWriter = 
                         new PrintWriter(fileName, charset);

        System.out.println(printWriter);
        printWriter.close();
    }
