PrintWriter PrintWriter(String) in Java

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

Syntax:

java.io.PrintWriter.PrintWriter(String fileName) throws FileNotFoundException

This method takes one argument. This method creates a new PrintWriter, without automatic line flushing, with the specified file name.

Parameters: One parameter is 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.

Throws:

1. FileNotFoundException - If the given string does not denote an existing, writable regular file and a new regular file of that name cannot be created, or if some other 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.FileNotFoundException;
import java.io.PrintWriter;

public class PrintWriterPrintWriter3 {
    public static void main(String[] args) 
                throws FileNotFoundException {
        String fileName = "D:\\hello.txt";

        PrintWriter printWriter = new PrintWriter(fileName);

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

Output:
