The Vector class implements a growable array of objects.C# 複製 [Android.Runtime.Register("java/util/Vector", DoNotGenerateAcw=true)] [Java.Interop.JavaTypeParameters(new System.String[] { "E" })] public class Vector : Java.Util.AbstractList, IDisposable, Java.Interop.IJavaPeerable, ...
Vector 在JDK1.0 的时候就存在的,但是ArrayList是在JDK1.2 的时候才出现的,所以Vector 在目前的开发中也用的不多,主要是它实现线程安全的方式比较低效,但是如果有一天Java 将synchronized锁的效率提高了,那Vector依然是一个不错的选择
在Applet 中有一块画布(Canvas) 和一个(Panel), 而Panel 中放着用户要输入的信息,根据这些信息把参数传递到canvas 中,这时在Java 中用一个接口(Interface), 而在接口中需用一个Vector 去传递这些参数。另外,在一个类向另一个类参数传递就可以用这种方法。 例如: import java.util.Vector interface codeselect{...

Therefore, it would be wrong to write a program that depended on this exception for its correctness: the fail-fast behavior of iterators should be used only to detect bugs. As of the Java 2 platform v1.2, this class was retrofitted to implement the List interface, making it a member of ...
