Charset defaultCharset() method in Java with Examples

The defaultCharset() method is a built-in method of the java.nio.charset which returns the charset object for the default charset. The default charset is basically determined by the Java virtual machine and it basically depends on the charset which is in the underlying operating system of the machine. In short, the result will vary from machine to machine.

Syntax:

public static Charset defaultCharset()

Parameters: The function does not accepts any parameter.

Return Value: The function returns a charset object for the default charset.

Below is the implementation of the above function:

Program 1:

// 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)
    {

        // Get the default charset of the machine
        Charset cs = Charset.defaultCharset();

        System.out.println("The default charset of the machine is :" + cs.displayName());
    }
}

Output:

The default charset of the machine is :US-ASCII
