How can I get String from Bytes

Question

I want to get String from array of bytes but i have some trouble from byte that it's lager more than 128. How can I do ???
Please hepl me. Thanks very much.

This program is only to show you what the relationships are between unsigned byte, signed byte, character, and binary values. Because of the constraints that Java has, the program code is not especially clean. Run the program and see if it helps. As has been said, the character output is dependent on the encoding in use.
Here is a sample of some of its output:
Unsigned byte= 189 Signed byte= -67 Character= � Binary= 10111101
Unsigned byte= 190 Signed byte= -66 Character= � Binary= 10111110
Unsigned byte= 191 Signed byte= -65 Character= � Binary= 10111111
Unsigned byte= 192 Signed byte= -64 Character= � Binary= 11000000
Unsigned byte= 244 Signed byte= -12 Character= � Binary= 11110100
Unsigned byte= 245 Signed byte= -11 Character= � Binary= 11110101
Unsigned byte= 246 Signed byte= -10 Character= � Binary= 11110110
public class ATest {
    public static void main(String[] args) {
        int in;
        byte by;
        String bin;
        char chr;
        for(in=0; in<256; in++) {
            // create a byte whose binary value is equal to the;
            // integer loop counter;
            by = (byte)in;
            // mask off sign extension [that I don't agree with!] and;
            // cast the resultant 8 bits to a char;
            chr = (char)(by & 0x00ff);
            // since there's no Byte.toInteger, must cast to int to get;
            // binary string and then delete unwanted portion of string;
            if(in<128) {
                bin = Integer.toBinaryString((int)by);
            } else {
                bin = Integer.toBinaryString((int)by).substring(24);
            // print everything;
            System.out.println(
                "Unsigned byte= "+in+
                " Signed byte= "+by+
                " Character= "+chr+
                " Binary= "+bin);
}
