reading a file encoded in utf-8 in java can be accomplished using several classes from the java standard library. a common approach is to use `bufferedreader` along with `inputstreamreader`. here’s a step-by-step tutorial on how to read a utf-8 encoded file in java, along with a code example.

step 1: set up your java environment
make sure you have jdk installed on your machine. you can check if java is installed by running `java -version` in your terminal or command prompt.

step 2: create a utf-8 encoded file
before you read a file, you'll need a utf-8 encoded file. you can create a text file named `example.txt` with utf-8 encoding using any text editor.

here’s an example content for `example.txt`:


step 3: write the java code to read the file
you can read the file using the following code snippet:



explanation of the code
1. **imports**: the necessary classes are imported from the `java.io` package.
2. **file path**: the path to the file you want to read is specified.
3. **bufferedreader**: this class reads text from a character-input stream, buffering characters to provide for the efficient reading of characters, arrays, and lines.
4. **inputstreamreader**: this class bridges byte streams to character streams, allowing you to specify the character encoding (utf-8 in this case).
5. **try-with-resources statement**: this statement ensures that each resource is closed at the end of the statement. it’s a good practice to manage resources like file streams.
6. **reading lines**: the `readline()` method reads a line of text. it returns `null` when the end of the stream is reached.
7. **error handling**: any `ioexception` that occurs is caught and printed to the console.

step 4: compile and run the java program
1. save your java code in a file named `readutf8file.java`.
2. open your terminal or command prompt.
3. navigate to the directory where your file is saved.
4. compile the java program using:

5. run the compiled java program using:
