until now i'm using bytebuffer but i can't view the result
my code is

ByteBuffer bb = ByteBuffer.allo cate(4);
bb.order(ByteOr der.LITTLE_ENDI AN);
bb.putInt(9995) ;
System.out.prin tln("x = "+ bb.toString());

i no have idea to print the bb..

Did you want to make the println

Code:

System.out.println("x = " + Arrays.toString(bb.array()));

instead?

thanks that's work for me...
but the result is in decimal...
can you give me a hint how to get the result in hex like [0b,27,00,00]

i try code like this

Code:

        ByteBuffer  bb = ByteBuffer.allocate(4);
        bb.order(ByteOrder.LITTLE_ENDIAN);
        bb.putInt(9995);
        //bb.putInt(43690);
        String xx = Arrays.toString(bb.array());

        String yy;
        yy = xx.substring(1,3);
        int i = Integer.parseInt(yy);
        String hex1 = Integer.toHexString(i);
        System.out.println("Hexa : " + hex1);

the result is "Hexa : b" not "Hexa : 0B"

the code has problem when put integer 43690(0xAAAA in hex) the result in array is [-86, -86, 0, 0] -86 when convert in java the result is ffffffAA not AA

would you help me againt :)

You want to try something like

Code:

System.out.print("x = ");
for (byte b : bb.array()) {
	System.out.printf("%2s", Integer.toHexString(b) + " ");
}

Read all about those formatters in the API specs for the Fomatter class.
