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:
// 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) { // First charset Charset first = Charset.forName("UTF16"); // Second charset Charset second = Charset.forName("UTF-8"); // Compares and print System.out.println(first.compareTo(second)); }} |
Output:
-7
Program 2:
// Java program to demonstrate// the above functionimport java.nio.charset.Charset;import java.util.Iterator;import java.util.Map; public class GFG { public static void main(String[] args) { // First charset Charset first = Charset.forName("ISO-2022-CN"); // Second charset Charset second = Charset.forName("ISO-2022-CN"); System.out.println(first.compareTo(second)); }} |
Output:
0
