Java String getBytes(Charset charset)
Now let us implement and accept the charset according to which string has to be encoded while conversion into bytes. There are many charset defined and are discussed below.
Syntax
public byte[] getBytes(Charset charset);
- US-ASCII: Seven-bit ASCII, a.k.a. ISO646-US, a.k.a. the Basic Latin block of the Unicode character set
- ISO-8859-1: ISO Latin Alphabet No. 1, a.k.a. ISO-LATIN-1
- UTF-8: Eight-bit UCS Transformation Format
- UTF-16BE: Sixteen-bit UCS Transformation Format, big-endian byte order
- UTF-16LE: Sixteen-bit UCS Transformation Format, little-endian byte order
- UTF-16: Sixteen-bit UCS Transformation Format, byte order identified by an optional byte-order mark.
Example
Java
// Java code to Illustrate Working of getByte() Method // using Different Character Sets // Importing required classes import java.io.*; // Main class public class GFG { // Main driver method public static void main(String args[]) { // Declaring and initializinga string String gfg = new String( "Geeks for Geeks" ); // Displaying string values before conversion System.out.println( "The String before conversion is : " ); System.out.println(gfg); // Try block to check for exceptions try { // Converting the string into byte // using getBytes() method byte [] b = gfg.getBytes( "UTF-16" ); // Displaying converted string // after conversion into UTF-16 System.out.println( "The String after conversion into UTF-16 is : " ); // Iterating over the string for ( int i = 0 ; i < b.length; i++) { System.out.print(b[i]); } System.out.print( "\n" ); // Converting the above string into byte // using getBytes() method byte [] c = gfg.getBytes( "UTF-16BE" ); // Displaying converted string // after conversion into UTF-16BE System.out.println( "The String after conversion into UTF-16BE is : " ); for ( int i = 0 ; i < c.length; i++) { System.out.print(c[i]); } } // Catch block to handle exceptions catch (UnsupportedEncodingException g) { // Display message when exceptions occurs System.out.println( "Unsupported character set" + g); } } } |
Output
The String before conversion is : Geeks for Geeks The String after conversion into UTF-16 is : -2-107101010101010701150320102011101140320710101010101070115 The String after conversion into UTF-16BE is : 07101010101010701150320102011101140320710101010101070115
String.getByte() Method in Java
In Java, getBytes() encodes a string into a sequence of bytes using the named character set and storing the result into a new byte array. This function can be implemented in two ways. Both ways are discussed below as follows:
- getBytes()
- getBytes(Charset charset)
Let us discuss and implement the first use case which is as follows:
