1. 使用while循环实现无限循环 while循环是最常见的实现无限循环的方式之一。只需确保循环条件始终为真即可。 语法: while (true) { // 循环体 } 示例: public class InfiniteLoopExample { public static void main(String[] args) { int counter = 0; while (true) { System.out.println("Counter: " ...
2. While Loop Example Let us understand thewhileloop with a few examples. 2.1. Print all numbers from 1 to N To print all integers between 1 and 5 using awhile-loop, we can create a condition on a local variablecounterthat must not be less than or equal to 5. ...
The expression inside the round brackets following the while keyword is the second phase, the testing. The statements in the body are executed until the expression is evaluated to false. i++; The last phase of the while loop is the updating. We increment the counter. Note that improper ...
2.--setIoRatio 用于设置 I/O 操作和非 I/O 操作(任务调度等)在 EventLoop 中的比例 3.--rebuildSelectors NioEventLoopGroup 中的 rebuildSelectors: 4.newChild() 他是用来创建eventLoop的 今天讨论下EventLoopGroup,这个在Netty中很重要,而且直接关系它的线程模型。
Node currentNode=firstNode;intcounter = 0;intloopCounter = 0;while((loopCounter < numberOfEntries) && (currentNode !=null)) {if(currentNode.data.equals(anEntry)) { counter++; }//end ifloopCounter++; currentNode=currentNode.next;
// atomicInteger.incrementAndGet() 使用上述方式实现:publicfinalintgetAndAddInt(Objecto,longoffset,intdelta){intv;do{// v 表示获取到的内存中的当前值v=getIntVolatile(o,offset);// compareAndSwapInt() 是一个原子操作、进行比较更新}while(!compareAndSwapInt(o,offset,v,v+delta));returnv;}...
loop、countedLoop、iteratedLoop、whileLoop 和 doWhileLoop: 创建不同类型的循环,包括 for 循环、while 循环 和 do-while 循环。 tryFinally: 把对方法句柄的调用封装在 try-finally 语句中。 提前编译 AOT 借助Java 9,特别是JEP 295,JDK 获得了提前(ahead-of-time,AOT) 编译器 jaotc。该编译器使用 OpenJDK...
