How to print the data in byte array as characters?

In my byte array I have the hash values of a message which consists of some negative values and also positive values. Positive values are being printed easily by using the (char)byte[i] statement.

Now how can I get the negative value?

Solution 1:

How about Arrays.toString(byteArray)?

Here's some compilable code:

byte[] byteArray = new byte[] { -1, -128, 1, 127 };
System.out.println(Arrays.toString(byteArray));

Output:

[-1, -128, 1, 127]

Why re-invent the wheel...

Solution 2:

If you want to print the bytes as chars you can use the String constructor.

byte[] bytes = new byte[] { -1, -128, 1, 127 };
System.out.println(new String(bytes, 0));
