Writing to a File
File gets created if its not existing.

try {
        BufferedWriter out = new BufferedWriter(new FileWriter("outfilename"));
        out.write("aString");
        out.close();
    } catch (IOException e) {
    }

Class BufferedWriter

java.lang.Object
== java.io.Writer
== java.io.BufferedWriter


public class BufferedWriter -- extends Writer

Write text to a character-output stream, buffering characters so as to provide for the efficient writing of single characters, arrays, and strings.

a Writer sends its output immediately to the underlying character or byte stream. Unless prompt output is required, it is advisable to wrap a BufferedWriter around any Writer whose write() operations may be costly, such as FileWriters and OutputStreamWriters. For example,

PrintWriter out
   = new PrintWriter(new BufferedWriter(new FileWriter("foo.out")));

will buffer the PrintWriter's output to the file. Without buffering, each invocation of a print() method would cause characters to be converted into bytes that would then be written immediately to the file, which can be very inefficient.

Write text file

import java.io.BufferedWriter;
import java.io.File;
import java.io.FileWriter;
import java.io.Writer;

public class Main {
  public static void main(String[] args) throws Exception {
    Writer writer = null;

    String text = "This is a text file";

    File file = new File("write.txt");
    writer = new BufferedWriter(new FileWriter(file));
    writer.write(text);
    writer.close();

  }
}
