Java: List the available character sets in charset objects

Java Basic: Exercise-40 with Solution

Write a Java program to list the available character sets in charset objects.

Sample Solution:

Java Code:

import java.nio.charset.Charset;

public class Exercise40 {
    public static void main(String[] args) {
        System.out.println("List of available character sets: ");
        
        // Iterate through the available character sets and print their names
        for (String str : Charset.availableCharsets().keySet()) {
            System.out.println(str);
        }
    }
}

Explanation:

In the exercise above -

  • First, import the Charset class from the "java.nio.charset" package.
  • In the "main()" method, it prints the header "List of available character sets."
  • It uses a for-each loop to iterate through the keys (character set names) in the set of available character sets provided by Charset.availableCharsets().keySet().
  • Inside the loop, it prints each character set name on a separate line.
  • Finally, when you run the program, it will list and display the names of all available character sets (encodings) supported by your Java runtime environment.

Sample Output:

List of available character sets:
