Java.lang.String.getBytes() Method

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

Following is the declaration for java.lang.String.getBytes() method

public byte[] getBytes(String charsetName) throws UnsupportedEncodingException

charset − This is the name of a supported charset.

This method returns the resultant byte array.

UnsupportedEncodingException − If the named charset is not supported.

The following example shows the usage of java.lang.String.getBytes() method.

package com.tutorialspoint;

import java.lang.*;

public class StringDemo {

   public static void main(String[] args) throws Exception {
  
      // string with numbers and some special characters    
      String str = "!$0123@";
    
      // byte array with charset
      byte bval[] = str.getBytes("UTF8");
  
      // prints the byte array
      for (int i = 0; i < bval.length; i++) {
         System.out.println(bval[i]);
      }
   }
}

Let us compile and run the above program, this will produce the following result −
