Hi Karthik,
In Java language you can do that using he methods
toOctalString(),toHexString(),toBinaryString methods of the Integer and Long classes.
Or are you looking for the general rules of conversion?

to convert a decimal to octal :
say the decimal number was 70
- 70/8 = 8, remainder = 6
- 8/8 = 1, remainder = 0
- 1/8 = 0, remainder = 1
therefore, octal eqv of 70 is 0106, u can recheck this by
0*8^3 + 1*8^2 + 0*8^1 + 6*8^0 = 0+64+0+6 = 70
to convert a decimal to hexadecimal:
say the decimal number is 125
- 125/16 = 7, remainder = D(13)
- 7/16 = 0, remainder = 7
therefore, hexadecimal equivalent of 125 is 7D, u can recheck this by
7*16^1 + 13*16^0 = 112+13 = 125.
hope this helped!!
