To declare a method as a method that can accept a variable number of parameters, we can use the params keyword to declare an array, as follows:public static Int32add (params int32[] values){Int32 sum = 0;for (Int32 x = 0; x {Sum + =

Recently work is too busy, no way to seriously write a blog, but still have to take a good record of the daily study.All kinds of games are heavily used in the timekeeping function, whether it is directly displayed in the front-end UI, or in the

Generally, you can write multiple overload methods to adapt to different parameters. If you think there are many parameters that are not certain, you can use an array to store these parameters (parameters of the same data type ).Of course, for

Overview:This article mainly studies the performance of String concatenation in Java. The test code in the original article is not functionally equivalent, so the test of Concat is of little significance. However, the original author gave a new

Recently, I started to study the efficiency of the string and learned about the conventional methods to improve the performance. Now consider a previous question: there is a long string, and the occurrence frequency of the letters must be counted.My

3. Update comments. The update process of comments is complicated because adding comments is an interactive process and static pages cannot complete this operation. The solution is to hand over the comments to another page (for example, remark. aspx.
