The GetAddress method is similar to gethostaddress, where the only difference is that the Gethostaddress method returns an IP address in the form of a string, and the GetAddress method returns an IP address in the form of a byte array. the GetAddress method is defined as follows:Public byte[] GetAddress ()The byte array returned by this method is signed. The value range of byte type in Java is -128?127. If a byte of the returned IP address is an integ

* @ throws ioexception */votemsg fromwire (byte [] input) throws ioexception ;} 3.5.1 text-based representation First, we will introduce a version that uses text encoding to encode messages. This protocol uses the UTF-8 character set to encode the text. A message starts with a so-called "magic string", that is, a character sequence, which is used by the recipient to quickly distinguish the message of the voting protocol from the random arrival of sp

Java Interface Programming (8) ------ combo box (drop-down list) This article is my learning notes, welcome to reprint, but please note the Source: http://blog.csdn.net/jesson20121020 Similar to the function of a group of single-choice buttons, a combo (drop-down list) forces users to select only one possible element from a group.

This week I will continue the sixth week of content, in the sixth week we learn the interface, because the reason for the holiday and sixth week of knowledge is very important, so this week the teacher through the explanation of the example with us to review the sixth weeks of knowledge points, and the interface chapter of the remaining knowledge points also do the explanation. Impressed by the shallow copy and deep copy in the clone, began to have some points not clear their differences in wher

This article is your own study notes, welcome reprint, but please indicate the source: http://blog.csdn.net/jesson20121020similar to the functionality of a set of radio buttons, a combo box (drop-down list) also forces users to select only one of a set of possible elements, but this approach is more compact and makes it easier to change the contents of a drop-down list without confusing the user. In the following example, the JComboBox combo box starts with some elements, and then when a button
