From: mike on 14 Jun 2010 04:44 Hi, I have a base represented as: 0x011B0000 To this I have to add an offset represented as this: 0x5900 How can I add the offset and see the resulting hex code? br, //mike

Add the two numbers then display the result in hex. There's more than one way to display the result in hex. The simplest might be to use <http://java.sun.com/javase/6/docs/api/java/lang/Integer.html#toHexString(int)> System.out.println( Integer.toHexString( 0x011B0000 + 0x5900 )); The String representation of an 'int' has absolutely nothing whatsoever at all in the least to do with how to calculate with it. An integer is an integer is an integer regardless of the numerals used to represent its value. A number and a numeral are not the same thing. It is a good idea to get very familiar with the fundamental Java API, such as java.lang.*, java.util.* and java.io.*. Those fall under the category of elementary Java knowledge. Read and study the Javadocs for those packages and their classes. -- Lew
