formatting output in printstream

[subhajit paul]

hi all,

lets say i have a byte array declared as:

byte bytearray[]={(byte)0x2a,(byte)0x0a};

when i use

while(int i=0;i<bytearray.length;i++)//line 1
System.out.printf("%x ",bytearray[i]);//line 2

i get an output like: 2a a

can anyone suggest how to format my output as : 2a 0a

and when line 2 is changed to :

System.out.printf("%2x ",bytearray[i]);

when i get an output like: 2a a?

TIA
