我希望嵌套的for-loop从字符数组列表(arr1)中删除包含任何字母pre-defined的任何单词,该单词从字符串数组列表中删除(arr2)。 程序在进入“单词移除器”方法(退出代码0)后过早退出,并且在之后未到达打印方法。 这是for-loop for (int i = 0; i < arr1.size(); i++){ //for each character in the arra...

Loop through the items of a HashMap with a for-each loop.Note: Use the keySet() method if you only want the keys, and use the values() method if you only want the values:ExampleGet your own Java Server // Print keys for (String i : capitalCities.keySet()) { System.out.println(...
使用for/in与“普通”for 之间的最基本区别是,您不必使用计数器(通常称为i或count)或Iterator。参见清单 1,它显示了一个使用的Iterator的for循环: 清单1. for 循环,旧式学院风格 public void testForLoop(PrintStream out) throws IOException { List list = getList(); // initialize this list elsewhere ...

Eclipse Collections Eclipse Collections is a collections framework for Java. It has JDK-compatible List, Set and Map implementations with a rich API, additional types not found in the JDK like Bags, Multimaps and set of utility classes that work with any JDK compatible Collections, Arrays, Maps...
For example, here is a class that uses a semaphore to control access to apool of items: 通过semaphore的构造方法可以确定所有权限的最大个数,使用Semaphore的acquire()方法(无参数)可以获得一个permit,只要线程获取的次数<创建的个数就无需阻塞,如果超过构造时最大的个数,就进行阻塞,而semaphore的release()...
