CharsetDecoder maxCharsPerByte() method in Java with Examples
The maxCharsPerByte() method is a built-in method of the java.nio.charset.CharsetDecoder class which returns the maximum number of characters that will be produced for each byte of input. This value may be used to compute the worst-case size of the output buffer required for a given input sequence.
Syntax:
public final float maxCharsPerByte()
Parameters: The function does not accepts any parameter.
Return Value: The function returns the maximum number of characters that will be produced for each byte of input.
Below is the implementation of the above function:
Program 1:
// Java program to demonstrate // the above function import java.nio.charset.*; import java.util.Iterator; import java.util.Map; public class GFG { public static void main(String[] args) { // Gets the charset Charset charset = Charset.forName( "ISO-2022-CN" ); // Get the CharsetDecoder CharsetDecoder decoder = charset.newDecoder(); // Prints the maxCharsPerByte System.out.println( "The maxCharsPerByte for " + "ISO-2022-CN is " + decoder.maxCharsPerByte()); } } |
Output:
The maxCharsPerByte for ISO-2022-CN is 1.0
Program 2:
// Java program to demonstrate // the above function import java.nio.charset.*; import java.util.Iterator; import java.util.Map; public class GFG { public static void main(String[] args) { // Gets the charset Charset charset = Charset.forName( "x-windows-949" ); // Get the CharsetDecoder CharsetDecoder decoder = charset.newDecoder(); // Prints the maxCharsPerByte System.out.println( "The maxCharsPerByte for " + "ISO-2022-CN is " + decoder.maxCharsPerByte()); } } |
Output:
The maxCharsPerByte for ISO-2022-CN is 1.0
