Java concurrency series [7] ---- CountDownLatch source code analysis, CountDownLatch is a useful tool class. With it, we can intercept one or more threads so that they can be executed after a certain condition is ripe. It provides a counter internally. When constructing a lock, you must specify the initial value of the counter and the initial value of the counter must be greater than 0. In addition, it also

row to column, how to think about it, here we first in the traditional way, use the case when, and then according to the case when the condition of the sum. The SQL statements are as follows:1 SELECT Empid,2SUM (case when empid=2Then Qty end) as N'customer consumption amount of No. 2nd',3SUM (case when Empid=3then qty End) as N'customer consumption amount of No. 3rd',4SUM (case when empid=4Then Qty end) as N'customer consumption amount of No. 4th',5SUM (case when empid=5Then Qty end) as N'custo

the number of times the statement is run.Swift provides two types of for loops: For-in in a range, sequence. A collection or series that runs once for each element. The for-condition-increment repeats until a particular condition is met, typically incrementing the counter after each cycle. For-inYou can use the for-in loop to iterate through the elements of a collection, such as a range of numbers, an element in an array, or a chara
