I'm trying to convert a number from an integer into an another integer which, if printed in hex, would look the same as the original integer.

For example:

Convert 20 to 32 (which is 0x20)

Convert 54 to 84 (which is 0x54)

解决方案

public static int convert(int n) {

return Integer.valueOf(String.valueOf(n), 16);

}

public static void main(String[] args) {

System.out.println(convert(20)); // 32

System.out.println(convert(54)); // 84

}

That is, treat the original number as if it was in hexadecimal, and then convert to decimal.
