, all non-static constructors are also referred to as instance constructors.　2. Static ClassWe often want the class to contain only static members, and cannot be used to instantiate objects such as the console. A simple way to do this is to use a static class instead of setting the class's constructor to private. A static class can contain only static members and does not require an instance constructor because, by definition, it cannot be instantiated at all. However, a static class can have a

1 Word Length (4 points)Topic content:Your program reads a line of text, separated by a space into several words, to '. ' End. You want to output the length of each word in this line of text. The words here are not language-related, and can include various symbols, such as "it's" to count a word, length 4. Note that there may be contiguous spaces in the row.Input format:Enter a line of text in a row to '. ' End, the ending period cannot be counted within the length of the last word.Output format

What can I do in ten minutes? I chose the definition of functional programming on Wiki to see how much I can read in ten minutes (on the premise that I can understand the content ), because the first half of this Wiki is introductory and there is not much complicated logic to understand, the reading is smooth and the results are as follows: 1. Open a browser, search for keywords from Google, and open the Wiki webpage,30 seconds. 2. Read the
