Last Updated :

The compareTo() method is a built-in method of the java.nio.charset compares two charsets with each other. A comparison is done by their canonical names, without regard to case.
Syntax:
public final int compareTo?(Charset second)
Parameters: The function accepts a single mandatory parameter second which specifies the charset to be compared with.
Return Value: The function returns an integer value which can be negative, positive or zero after comparing both the offsets.
Below is the implementation of the above function:
Program 1:
import java.nio.charset.Charset;
import java.util.Iterator;
import java.util.Map;
public class GFG {
public static void main(String[] args)
{
Charset first = Charset.forName( "UTF16" );
Charset second = Charset.forName( "UTF-8" );
System.out.println(first.compareTo(second));
}
}
|
Program 2:
import java.nio.charset.Charset;
import java.util.Iterator;
import java.util.Map;
public class GFG {
public static void main(String[] args)
{
Charset first = Charset.forName( "ISO-2022-CN" );
Charset second = Charset.forName( "ISO-2022-CN" );
System.out.println(first.compareTo(second));
}
}
