Step by Step solution about How to resolve the algorithm Terminal control/Display an extended character step by step in the Java programming language

Main Class: The program defines a public class named Main that contains the program's entry point.

Entry Point: The main method is the entry point of the program. It throws an UnsupportedEncodingException to handle potential errors related to encoding.

Stream for Output: The program creates a PrintStream object named writer that is associated with the standard output stream (System.out). It ensures the output is written directly to the console. The true parameter indicates that automatic flushing should be enabled, and the "UTF-8" parameter specifies that the UTF-8 character encoding should be used.

Output to Console: The program uses the writer object to print two lines of text to the console:

1. £ (the pound sterling currency symbol): This character is encoded using UTF-8, which allows for non-ASCII characters to be printed.
2. "札幌" (the Japanese word for "Sapporo"): This string is also encoded using UTF-8, allowing it to be displayed correctly on the console.

Encoding Handling: The main method catches any UnsupportedEncodingException that may occur while setting the encoding for the PrintStream. This ensures that the program handles potential encoding issues gracefully. By default, the platform's default encoding is used if no encoding is specified.

import java.io.PrintStream;
import java.io.UnsupportedEncodingException;

public class Main
{
    public static void main(String[] args) throws UnsupportedEncodingException
    {
        PrintStream writer = new PrintStream(System.out, true, "UTF-8");
        writer.println("£");
        writer.println("札幌");
    }
}
