Question

Convert UTF-8 to UTF-16 and Back

Write two Java programs and verify that they work.

Program 1 should:

• Read a UTF-8 encoded text file
• Print to the console the hex values for the bytes it read in.
• Convert the text to UTF-16
• Print to the console the hex values for the converted bytes
• Write the UTF-16 text to a file

Program 2 should do the same as program 1, except program 2 goes from UTF-16 to UTF-8

Submit:

1. UTF8ToUTF16.java
2. UTF16ToUTF8.java
3. A sample utf8 input file
4. A sample utf 16 output file
5. A sample utf 16 input file
6. A sample utf 8 output file
7. A screenshot of your computer running program 1
8. A screenshot of your computer running program 2

import java.io.*;

public class WriteUTF8 {
  
   public static void main(String[] args) {
       File file = new File("utf8_output.txt");
       FileOutputStream fs= null;
       try {
           fs = new FileOutputStream(file);
       }
       catch (FileNotFoundException fnfe) {
           System.err.println("file not found");
       }
       try {
           fs.write("Фёдор".getBytes("UTF-8"));
           fs.close();
       }
       catch(IOException ioe){
           System.err.println("unable to write to file");
       }
   }
}

WriteUTF16.java

import java.io.*;

public class WriteUTF16 {
  
   public static void main(String[] args) {
       File file = new File("utf16_output.txt");
       FileOutputStream fs= null;
       try {
           fs = new FileOutputStream(file);
       }
       catch (FileNotFoundException fnfe) {
           System.err.println("file not found");
       }
       try {
           fs.write("Фёдор".getBytes("UTF-16"));
           fs.close();
       }
       catch(IOException ioe){
           System.err.println("unable to write to file");
       }
   }
}

WriteUTF8.java

import java.io.*;

public class WriteUTF8 {
  
   public static void main(String[] args) {
       File file = new File("utf8_output.txt");
       FileOutputStream fs= null;
       try {
           fs = new FileOutputStream(file);
       }
       catch (FileNotFoundException fnfe) {
           System.err.println("file not found");
       }
       try {
           fs.write("Фёдор".getBytes("UTF-8"));
           fs.close();
       }
       catch(IOException ioe){
           System.err.println("unable to write to file");
       }
   }
}
