The a.txt file is as follows:
Aaaaaaa AAAA bbbbbb ccccccccccc dddd

Aaaaaaaaaaaa bbbbbbbbbbbbb cccccccccccccccccccc
Aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
Aaaaaaaaaaaaaaaaaaaaaaaaaaaa bbbbbbbb
Aaaaaaaaa ccccccccc bbbbbbbbbbbbbbb ddddddddddddddddddd
Find the rows with the largest number of characters (excluding spaces) in the text in batch and output them. It is obvious that the contents are c
Include|js First Example:
File1:
String str = "AAAAA";
%>
File2:
str = str + "BBBBB";
%>
Results:
Error accessing File1, indicating that variable STR cannot be resolved in file2.
Analysis:
When requesting File1, Tomcat first converts two JSP files to servlet (. java) files. You then attempt to compile both into. class files, at which point File1 compiles normally, and file2 does not compile.
Conclusion:
Unlike the Include-file directive, which merges two files into a servlet file for
the same rowkey of the same Column Family in the same table, what will happen?

Put 'T', 'r1', 'cf ', 'aaaaaaaaaaaaaaa' put 'T', 'r1', 'cf', 'bbbbbbbbbbbbbbbb'
In the preceding operation, the rowkey of the cf column cluster of t on Master1 is r1, the value is aaaaaaaaaaaaaaa, And the rowkey of the cf column cluster of t on Master2 is r1 at the same time, the value is bbbbbbbbbbbbbbb

When the function call ends, the local variable first goes out of the stack, then the parameter, and the top pointer of the stack points to the address of the initial storage, that is, the next instruction in the main function, where the program continues to run.

Java Inheritance Analysis and java inheritance
After learning java, I started it again and suddenly found that I still don't understand inheritance. So I did a test to analyze it.
Although there are not many codes, it is not easy for me to fully understand them, so let's take a look,
