What are the rules for string size comparisons? For example: "Ten", "10a", "a", "abc" How do they sort in ascending descending order?? Ask for rules!! Reply to discussion (solution) As far as I know, the rule of comparison between them is: The first letter of the ASCLL size comparison if the same is compared to the second one.

Comparison of languages PHP is the server scripting language that interprets execution, first PHP has a simple and easy-to-follow feature. Grammar and C are more alike, so programmers who have studied C can quickly become familiar with the development of PHP. Java needs

In the previous article--js comparison version number (a), the author uses JS to use its own method complex processing the next only a pair of string version number comparison. Why is it complicated, because it does not apply to a bunch of version number comparisons, need more code, then how to solve it?In fact,JS has been packaged for us sorting function sort (), can be a good convenience to solve the stri

The function of comparing version number is often needed in the system of the client, but comparing the version number can not use the method of CompareTo in the way of the string comparison completely;This requires that we summarize the general rules of the version number, design a comparison algorithm and encapsulate it as a common method to use:Usually version number such as: 1.3.20.8,6.82.20160101,8.5A/

The difference between the Equals method used by string and = =The difference between the Equals method and = = First you know that string can be used as an object or as a base type. This refers to use as a basic type only refers to the use of methods, such as String s = "Hello", it is used as a primitive type int, such as int i = 1, and as an object to use, it means to create a new object by using the new keyword, such as String s = new String ("Hello"). But its internal action actually create

Sort : Sorts a sequence of objects according to a keyword;stability : Suppose A was originally in front of B. And a=b, after sort a is still in front of B;For example: Insert sort, bubble sort, merge sort, count sort, base sort, bucket sort instability: Suppose A was originally in front of B. and A=b. After sorting a may appear behind today's B.For example: Hill sort , high-speed sort, select Sort, heap sort internal sorting : memory that does not occupy extra memory or consumes constant;For ex

each time.Because of the immutable nature of the string class, you should consider using the StringBuffer class to improve program efficiency when a string variable needs to change its value frequently.*************************************************************************************************************** *********************************************The difference between equals and = = in JavaThe data types in Java can be divided into two categories:1.
