Java Program to Convert byte[] Array to String

To convert a byte [] to a String, let's first declare and initialize a byte array.

//Byte Array
byte[] arr = new byte[]{78,　79,　33};

Now let's get a String that contains an array within it.

String str = new String(arr);

Let's see a complete example of converting a byte array to a String.

Example

public class Demo {
　　　public static void main(String args[]) {
　　　　　　//Byte Array
　　　　　　byte[] arr = new byte[]{78,　79,　33};
　　　　　String str = new String(arr);
　　　　　　//String
　　　　　　System.out.println("String = ",+str);
　　　}
}

Output Result

String = NO!
