these are the loop counters) are initialized. This is an optional part of the loop as the variables can be initialized before the loop.This executes only once when the loop starts.

For example, if you want to show a message 100 times, then you can use a loop. It's just a simple example; you can achieve much more with loops. In the previous tutorial, you learned about Java for loop. Here, you are going to learn about while and do...while loops. Java while...
For example, with a sufficiently intelligent stylesheet, you could generate PDF or PostScript output from the XML data. But generally, XSLT is used to generate formatted HTML output, or to create an alternative XML representation of the data. In this section, an XSLT transform is used to ...
Java内存模型主要目标是定义程序中各个变量的访问规则,即在虚拟机中将变量存储到内存和从内存中取出变量的操作底层细节。此处的变量(Variables)与Java编程中的变量有所区别,它包括了实例字段,静态字段,和构成数组对象的元素,但不包括局部变量与方法参数,因为后者是线程私有的,不会被共享,自然不会出现竞争问题。
For example, you could use this technique to produce a stream of CPU load or memory usage. However, you should use this with caution. It is similar to an infinite loop.You could also use generate to create an infinite random number supply; for example:...
variables.put("initUserId","wangxin"); variables.put("leaveReason","想休假了"); 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 2、使用el表达式来做流程的动态属性或方法定义 比如完成一个“请假销假”的任务,需要流程发起者销假,销假环节就能找到正确的签收者(activiti:assignee)了: ...
