other code waits until it runs Out.So this time, the code needs to be executed by the THREAD.At this point, in order to differentiate which code can be executed by the thread, Java provides a run () in the thread class to contain the code that is executed by the Thread.C: Create an ObjectD: Start ThreadCustomize the Mythread class and override the Run () method1 //note: When you create this class, you inherit the thread class2 3 public classMyThread
, ROWID lookup):This is the quickest way for Oracle to access single-line data because the location of row storage is recorded in rowID.3. Index Scan:In the index, in addition to storing the value of each index, the index stores the ROWID value corresponding to the row with this value, the index scan is divided into two steps 1, the scan index gets rowid;2, and t
After the power of 4 is written in binary form, it is easy to find a feature:
The binary has only one 1 (1 in odd position), and 1 followed by an even number of 0, so the question can be converted to determine whether 1 followed by an even number of 0.4 of the integer power of the binary numbers are (4) 100, (16) 1000
