But, in the standard method, we took the input in the code itself which is not an efficient way for writing a code. This is because, if it is written in the code itself then, for every testcase, we must go and make changes in the code. So instead, we make use of the Scanner c...

看到没有,hashCode 方法里面的int PRIME = true没有了,取而代之的是final int PRIME = 59。 这已经是 java 文件了,要是这地方还是 true 的话,那么妥妥的编译错误: 而且通过 delombok 生成的源码,也解答了我之前的一个疑问: 看class 文件的时候,感觉 PRIME 这个变量没有使用过呢,那么它的意义是什么呢? 但...

At the end when the algorithm terminates, all the numbers in the list that are not marked are the prime numbers. Here’s what the code looks like: publicstaticList<Integer>sieveOfEratosthenes(intn){booleanprime[] =newboolean[n +1]; Arrays.fill(prime,true);for(intp=2; p * p <= n;...

由于使用的 ReentrantLock(CAS),所以每次除成功获取锁的线程以外,其他线程都在自旋(内部也是使用for(;;)的方式),所以导致 CPU 过高。 另外我们通过自定义 ThreadFactory 的方式为线程池中的线程进行命名(主要是为了之后的方面定位线程),我们尝试使用前面总结的思路来定位问题。
