Note that, in this example, the vector function is included in the script block marked as "vector functions" with corresponding annotations. However, it should be noted that each circular element (I .e. the ball) moves along its own velocity vector as shown below (seeinitFunction ):

the Tiobe ranking is still 100, in 2016 years a year from 169th to 137.
So who will spend the annual programming language of 2017? We predict that C + +, Swift, Julia and Typescript will all be strong contenders for this position.

Copy Code code as follows:
str1= "ABC"
str2= "ABC"
In Java, for literal strings, a table is maintained inside the JVM, so if in Java, str1 and str2 are the same string objects. In Ruby, str1 and str2 are completely different objects. Similarly, the operation of a string object in Java produces a new object, while Ruby manipulates the same object, such as:
