We will also learn how to convert byte array to String in Java.String to byte arrayWe can use String class getBytes() method to encode the string into a sequence of bytes using the platform's default charset. This method is overloaded and we can also pass Charset as argument.Here is a simple program showing how to convert String to byte array in java. package com.journaldev.util; import java.util.Arrays; public class StringToByteArray { public static void main(String[] args) { String str = "PANKAJ"; byte[] byteArr = str.getBytes(); // print the byte[] elements System.out.println("String to byte array: " + Arrays.toString(byteArr)); } } Below image shows the output when we run the above program.We can also get the byte array using the below code. byte[] byteArr = str.getBytes("UTF-8"); However if we provide Charset name, then we will have to either catch UnsupportedEncodingException exception or throw it. Better approach is to use StandardCharsets class introduced in Java 1.7 as shown below. byte[] byteArr = str.getBytes(StandardCharsets.UTF_8); That's all the different ways to convert String to byte array in java.Java byte array to StringLet's look at a simple program showing how to convert byte array to String in Java. package com.journaldev.util; public class ByteArrayToString { public static void main(String[] args) { byte[] byteArray = { 'P', 'A', 'N', 'K', 'A', 'J' }; byte[] byteArray1 = { 80, 65, 78, 75, 65, 74 }; String str = new String(byteArray); String str1 = new String(byteArray1); System.out.println(str); System.out.println(str1); } } Below image shows the output produced by the above program.Did you notice that I am providing char while creating the byte array?It works because of autoboxing and char `P' is being converted to 80 in the byte array. That's why the output is the same for both the byte array to string conversion.String also has a constructor where we can provide byte array and Charset as an argument. So below code can also be used to convert byte array to String in Java. String str = new String(byteArray, StandardCharsets.UTF_8); String class also has a method to convert a subset of the byte array to String. byte[] byteArray1 = { 80, 65, 78, 75, 65, 74 }; String str = new String(byteArray1, 0, 3, StandardCharsets.UTF_8); Above code is perfectly fine and `str' value will be `PAN'. That's all about converting byte array to String in Java.You can checkout more array examples from our GitHub Repository.Reference: getBytes API Doc In this post we'll see a Java program to convert a String to byte array and byte array to String in Java.Converting String to byte[] in JavaString class has getBytes() method which can be used to convert String to byte array in Java.getBytes()- Encodes this String into a sequence of bytes using the platform's default charset, storing the result into a new byte array.There are two other variants of getBytes() method in order to provide an encoding for String.getBytes(Charset charset)getBytes(String charsetName)import java.util.Arrays; public class StringToByte { public static void main(String[] args) { String str = "Example String"; byte[] b = str.getBytes(); System.out.println("Array " + b); System.out.println("Array as String" + Arrays.toString(b)); } } OutputArray [B@2a139a55 Array as String[69, 120, 97, 109, 112, 108, 101, 32, 83, 116, 114, 105, 110, 103] As you can see here printing the byte array gives the memory address so used Arrays.toString in order to print the array values.Conversion of string to byte array with encodingSuppose you want to use "UTF-8" encoding then it can be done in 3 ways.String str = "Example String"; byte[] b; try { b = str.getBytes("UTF-8"); } catch (UnsupportedEncodingException e) { // TODO Auto-generated catch block e.printStackTrace(); } b = str.getBytes(Charset.forName("UTF-8")); b = str.getBytes(StandardCharsets.UTF_8); Using str.getBytes("UTF-8") method to convert String to byte array will require to enclose it in a try-catch block as UnsupportedEncodingException is thrown. To avoid that you can use str.getBytes(Charset.forName("UTF-8")) method. Java 7 and above you can also use str.getBytes(StandardCharsets.UTF_8);Converting byte array to String in JavaString class has a constructor which takes byte array as an argument. Using that you can get the String from a byte array.String(byte[] bytes)- Constructs a new String by decoding the specified array of bytes using the platform's default charset.If you want to provide a specific encoding then you can use the following constructor-String(byte[] bytes, Charset charset)- Constructs a new String by decoding the specified array of bytes using the specified charset.public class StringToByte { public static void main(String[] args) { String str = "Example String"; // converting to byte array byte[] b = str.getBytes(); // Getting the string from a byte array String s = new String (b); System.out.println("String - " + s); } } OutputString - Example String Recommendations for learning (Udemy Courses)That's all for this topic Convert String to Byte Array Java Program.
