Charset forName() method in Java with Examples Last Updated : 29 Mar, 2019 Comments Improve Suggest changes Like Article Like Report The forName() method is a built-in method of the java.nio.charset returns a charset object for the named charset. In this function we pass a canonical name or an alias and its respective charset name is returned. Syntax: public static Charset forName?(String charsetName) Parameters: The function accepts a single mandatory parameter charsetName which specifies the canonical name or the alias name whose object name is to be returned. Return Value: The function returns a charset object for the named charset. Errors and Exceptions: The function throws three exceptions as shown below: IllegalCharsetNameException: It is thrown if the given charset name is illegal IllegalArgumentException : It is thrown if the given charsetName is null UnsupportedCharsetException : It is thrown if no support for the named charset is available in this instance of the Java virtual machine Below is the implementation of the above function: Program 1: Java // Java program to demonstrate // the above function import java.nio.charset.Charset; import java.util.Iterator; import java.util.Map; public class GFG { public static void main(String[] args) { // Gets the charset Charset first = Charset.forName("ISO-2022-CN"); // Prints the object System.out.println("The name for ISO-2022-CN is " + first); } } Output: The name for ISO-2022-CN is ISO-2022-CN Program 2: Java // Java program to demonstrate // the above function import java.nio.charset.Charset; import java.util.Iterator; import java.util.Map; public class GFG { public static void main(String[] args) { // Gets the charset Charset first = Charset.forName("UTF16"); // Prints the object System.out.println("The name for UTF16 is " + first); } } Output: The name for UTF16 is UTF-16 Program 3 Java // Java program to demonstrate // the above function import java.nio.charset.Charset; import java.util.Iterator; import java.util.Map; public class GFG { public static void main(String[] args) { try { // Gets the charset Charset first = Charset.forName(""); // Prints the object System.out.println("The name for null is " + first); } catch (Exception e) { // Prints the exception System.out.println("The exception is: " + e); } } } Output: The exception is: java.nio.charset.IllegalCharsetNameException: Program 4 Java // Java program to demonstrate // the above function import java.nio.charset.Charset; import java.util.Iterator; import java.util.Map; public class GFG { public static void main(String[] args) { try { // Gets the charset Charset first = Charset.forName("gopal"); // Prints the object System.out.println("The name for gopal is " + first); } catch (Exception e) { // Prints the exception System.out.println("The exception is: " + e); } } } Output: The exception is: java.nio.charset.UnsupportedCharsetException: gopal Reference: https://docs.oracle.com/javase/10/docs/api/java/nio/charset/Charset.html#forName(java.lang.String) Comment More infoAdvertise with us Next Article Introduction to Java G gopaldave Follow Improve Article Tags : Java Java-Functions Java-NIO package Java-Charset Practice Tags : Java Similar Reads Java Tutorial Java is a high-level, object-oriented programming language used to build web apps, mobile applications, and enterprise software systems.
