int to hexadecimal

[dale con]

Dear all

Can someone show me how to convert an int to a hexadecimal?

Many thanks

Have a look at the static Integer.toHexString() method.

Here's one method...

Convert to binary, then convert each "block" of 4 binary bits to a hex digit.

For example, consider 179. In binary, this is 10110011. Break this into blocks of 4 from right to left (since there might be leading zeros): 1011 0011. Then convert each of these blocks to a hex digit: b3.

Note:
To convert to octal, break the binary representation into blocks of 3 (from right to left): 010 110 011. Then convert each of these blocks to an octal digit: 263.
