Why use this feature?Each page in the project contains the product name, Logo, version and other information, I would like to change one, all the other changes.Some students say that all refer to a page "" is OK, but I hope that this information can be modified through the background code, modified to save to the database and a static class, in fact, the background directly read and write the referenced page or save to the properties file (property) is also possible, I think it's better to save
I. Break,continue,goto in JavaFirst break,continue is a keyword in Java, and Goto is a reserved word.Based on the ghost performance of Goto in C and C + +, I think Goto may still be a long-term bench in Java.Break: Forcibly exits the loop and does not perform subsequent steps in the loop.Continue: Launch the current loop, go back to the starting point of the loop, start a new loopExamples are as follows: //ContinueSystem.out.println ("//continue:"); for(inti = 0; I ) { if(i =

Text is to learn the network of articles on the summary, thank you for your selfless sharing.Java does not provide a goto feature, but it retains the goto keyword. In Java, you can use the break label and the continue label feature to implement the Goto feature in a simple version.Here's a little code to make a tip.Package se;/** * * Reference:http://blog.csdn.net/jamesfancy/article/details/1198210http://zhangkun716717-126-com.iteye.com/blog/933836Java se break and Continue
