Please tell me...
how to convert integer to hex in little endian format ?

example : i'm input int = 9995
then
the output in Array String is [0b,27,00,00]

r035198x

What have you done so far?

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

ByteBuffer bb = ByteBuffer.allocate(4);
bb.order(ByteOrder.LITTLE_ENDIAN);
bb.putInt(9995);
System.out.println("x = "+ bb.toString());

i no have idea to print the bb..

r035198x

Did you want to make the println

Expand|Select|Wrap|Line Numbers

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

Expand|Select|Wrap|Line Numbers

 
        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

Expand|Select|Wrap|Line Numbers

 
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.
