Java String getBytes()

The getBytes() method encodes a specified String into a sequence of bytes using the named charset, storing the result into a new byte array.

Note: The behavior of this method, when this string cannot be encoded in the given charset, is unspecified.

Example

Java Compiler

public class myClass { public static void main(String[] args) { String str = "ABCDEabcde"; byte[] arr = str.getBytes(); for(int i=0; i<arr.length; i++){ System.out.println(arr[i]); } } }

Output

65 66 67 68 69 97 98 99 100 101

Syntax

public byte[] getBytes() // or public byte[] getBytes(Charset charset) // or public byte[] getBytes(String charsetName)

Java String getBytes(Charset charset)

Encodes this String into a sequence of bytes using the given charset, storing the result into a new byte array.

Example

Java Compiler

import java.nio.charset.Charset; public class myClass { public static void main(String[] args) { String str = "ABCDEabcde"; byte[] arr = str.getBytes(Charset.forName("ASCII")); for(int i=0; i<arr.length; i++){ System.out.println(arr[i]); } } }

Output

65 66 67 68 69 97 98 99 100 101

Java String getBytes(String charsetName)

Encodes this String into a sequence of bytes using the named charset, storing the result into a new byte array.

Example

Java Compiler

public class myClass { public static void main(String[] args) { try{ String str = "ABCDEabcde"; byte[] arr = str.getBytes("ASCII"); for(int i=0; i<arr.length; i++){ System.out.println(arr[i]); } } catch (Exception e){ System.out.println(e.toString()); } } }
