13. If you need synchronized ArrayList or HashMap, you can wrap them. List list = Collections.synchronizedList(new ArrayList(...)); Map m = Collections.synchronizedMap(new HashMap(...)); Personally I find the "synchronized" methods in these collections not very useful in heavy threaded code. There are some …We would like to show you a description here but the site won’t allow us.Java Vector is a part of Java's Collection framework and implements the List interface. It is similar to an array, but with a key difference - a Vector in Java can grow and shrink dynamically to adapt to the data it's storing. This means it doesn't have a fixed size, which can be a significant advantage in various programming scenarios.Java 集合 Vector迭代器. 在这个例子中，我们将看到如何使用 Iterator 遍历 Vector 。. 步骤如下：. 1）创建一个 Vector. 2）使用 Vector 类的 add (Element E) 方法向其中添加元素. 3）通过调用 Vector 的 iterator () 方法获取迭代器。. 4）使用迭代器的 hasNext () 和 next () 方法遍历 ...

We can iterate over vector by the following ways: Simple for-loop. Enhanced for-loop. Iterators. Enumeration interface. Method 1: Simple for-loop. The idea is to run a for loop from start till the size of the vector. We can also iterate from n-1 to 0 to traverse in reverse order. Java.A constructor in Java is similar to a method that is invoked when an object of the class is created..
