This article is about how java can write and save txt files. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

The example code is as follows:

Package TEST;import java.io.BufferedWriter;import java.io.FileWriter;import java.io.IOException;public class BufferedWriterDemo {public static void main (String [] args) throws IOException {write ("E:\\ 1.txt"); / / run the main method} public static void write (String path) throws IOException {/ / convert writes to streams in the form BufferedWriter bw = new BufferedWriter (new FileWriter (path)); / / write one line at a time String ss = "test data" Bw.write (ss); bw.newLine (); / / Line wrap / / close stream bw.close (); System.out.println (write successful);}}

Java creates the txt file and saves the content

Import java.io.BufferedReader;import java.io.File;import java.io.FileInputStream;import java.io.FileOutputStream;import java.io.IOException;import java.io.InputStreamReader;import java.io.PrintWriter;public class txtExport {private static String path = "args /"; private static String filenameTemp;public static void main (String [] args) throws IOException {txtExport.creatTxtFile ("Hello"); txtExport.writeTxtFile ("Hello") } / * create file * * @ throws IOException*/public static boolean creatTxtFile (String name) throws IOException {boolean flag = false;filenameTemp = path + name + ".txt"; File filename = new File (filenameTemp); if (! filename.exists ()) {filename.createNewFile (); flag = true;} return flag } / * write file * * @ param newStr* new content * @ throws IOException*/public static boolean writeTxtFile (String newStr) throws IOException {/ / read the contents of the original file first, and then write boolean flag = false;String filein = newStr + "\ r\ n"; String temp = ""; FileInputStream fis = null;InputStreamReader isr = null;BufferedReader br = null;FileOutputStream fos = null;PrintWriter pw = null;try {/ / file path File file = new File (filenameTemp) / / read the file into the input stream fis = new FileInputStream (file); isr = new InputStreamReader (fis); br = new BufferedReader (isr); StringBuffer buf = new StringBuffer (); / / save the original contents of the file for (int j = 1; (temp = br.readLine ())! = null; jacks +) {buf = buf.append (temp) / / System.getProperty ("line.separator") / / the separator between lines is equivalent to "\ n" buf = buf.append (System.getProperty ("line.separator"));} buf.append (filein); fos = new FileOutputStream (file); pw = new PrintWriter (fos); pw.write (buf.toString (). ToCharArray ()); pw.flush (); flag = true;} catch (IOException E1) {/ / TODO automatically generates catch blocks throw e1 } finally {if (pw! = null) {pw.close ();} if (fos! = null) {fos.close ();} if (br! = null) {br.close ();} if (isr! = null) {isr.close ();} if (fis! = null) {fis.close ();}} return flag;}} Thank you for reading!
