Java String to byte[] (String contains object data)

Question

I am using a JavaScript to Applet object called JSObject and I get from my JSObject the value of a java object that I stored in my html page.

The java object is a byte[] but JavaScript converts it to a String.

So in the HTML page: object value = [B@ca0b6

In the Applet, the String value is also [B@ca0b6

Is there a way for me to convert this String value of [B@ca0b6 into the byte representation? I don't mean String.getByte() because that will convert the STRING [B@ca0b6 into byte[] data.

Thanks!

• Tasawer Khan: There are no objects in HTML. Do you mean the object you saved in JS?

Answer 1

No, you can't. This is the default toString() method, which does not output anything of the array contents. It contains only the type of the object (array of bytes) and the memory address within the JVM, in hex.

If you want to convert your array to String properly, use Arrays.toString(array)

• Vedar: Interesting, I'll need to find a different approach. Thanks!

Answer 2

You can use:

new String(bytearray, "UTF-8")

(change UTF-8 to something else (e.g., ISO-8859-1) if your bytes are not UTF-8.)

• C. K. Young: @Bozho: It's too bad the question isn't more explicit in what the OP wants. :-( Both your answer and mine are correct, depending on how the question is interpreted.
• Bozho: I assumed the "string" interferes not because it consists of the bytes, but because it is outputted as a string in html
