Converting byte array containing ASCII characters to a String

Question

I have a byte array that consists of ASCII characters that I wish to convert to a String. For example:

byte[] myByteArray = new byte[8];
for (int i=0; i<8; i++) {
    byte[i] = (byte) ('0' + i);
}

myByteArray should contain a string "12345678" after the loop. How do I get this string into a String variable?

Thanks!

Answer 1

Use

new String(myByteArray, "UTF-8");

String class provides a constructor for this.

Side note:The second argument here is the CharSet(byte encoding) which should be handled carefully. More here.

Answer 2

String aString = new String(yourByteArray);

or

String aString = new String(yourByteArray, "aCharSet"); 
//Replacing "aCharSet" with the appropriate chararacter set
