马克-to-win:Vector和ArrayList很类似,前面讲了二者的区别,就在于同步的问题上,Vector的使用是非常简单的:先创建一个,再用addElement()置入对象,以后用elementAt()取得那些对象 例:3.1.1 import java.io.*; import java.util.*; public class TestMark_to_win { public static void main(String args[]) { ...
This method is also equivalent to the expression lanewise(ADD, v). As a full-service named operation, this method comes in masked and unmasked overloadings, and (in subclasses) also comes in scalar-broadcast overloadings (both masked and unmasked). Specified by: add in class Vector<...
For any lane unset in the mask, the primitive operation is suppressed and this vector retains the original value stored in that lane. This method is also equivalent to the expression lanewise(ADD, v, m). As a full-service named operation, this method comes in masked and unmasked over...
What is the equivalent for Vector's of Java in Objective-C? answer: Try using NSMutableArray. The closest thing you will find is NSMutableArray, execpt that contrary to java Vector, it is not thread safe. If you do not need thread safety, NSMutableArray is nice. I suspect that if yo...

optional list operations,and permits all elements, including null. In addition to implementing the Listinterface, this class provides methods to manipulate the size of the array thatis used internally to store the list. (This class is roughly equivalent toVector, except that it is unsynchronized....
容器相关的操作及其源码分析 说明 1、本文是基于JDK 7 分析的。JDK 8 待我工作了得好好研究下。Lambda、Stream。 2、本文会贴出大量的官方注释文档,强迫自己...

We want to find the inverse of the vector 'a' which is equivalent to solving the equation: a-1a = 1 To solve this equation we can use the property that, ingeometric algebra, the square of a vector is a scalar, so, a2= |a|2 ...
