String to char array Java

I am stumped on this and I need some fresh eyes, I'm not sure why this code is doing this.

String string = new String(new char[] {(char) 0x01, (char) 0x02, ... ,(char) 0xFC});

The output is everything it should be up until the last number (the 0xFC) it returns a -4, I know its a hex value, but if I do the same with 252 the decimal value, it gives me a negative as well. I hope this is just a simple solution, and I just can't see it.

Thanks ahead of time.

A string to char array is as simple as

String str = "someString"; 
char[] charArray = str.toCharArray();

Can you explain a little more on what you are trying to do?

*** Update ***

if I am understanding your new comment, you can use a byte array and example is provided.

byte[] bytes = ByteBuffer.allocate(4).putInt(1695609641).array();

for (byte b : bytes) {
   System.out.format("0x%x ", b);
}

With the following output

0x65 0x10 0xf3 0x29
