Don't say much, just go straight to the picture.

Solve

Java file character input stream FileReader reads txt file garbled first code public class FileInAndOut {public static void main (String [] args) {/ / define the File object File file = new File of the file on the specified disk ("java / second semester / Android/ assignment requirements / java knowledge consolidation / work5.txt"); if (! File.exists () {System.out.println ("sorry, file that does not contain the specified path");} else {/ / create the FileReader object try {FileReader fr = new FileReader (file) based on the File object of the specified path Char [] data = new char [51]; / / define the char array int length = 0 While ((length = fr.read (data)) > 0) {/ / read data in the file String str = new String (data,0,length) / / create a String object System.out.println (str) based on the contents of the read file; / / output the read content} fr.close () / / close the stream} catch (Exception e) {/ / TODO Auto-generated catch block e.printStackTrace () }} the console output is as follows

The reason is

The most basic unit of character stream processing in Java is the Unicode symbol (size 2 bytes), so we need to change the encoding format of the file to utf-8 when we save it.

The result after running is
