Read MoreHow to search for a value in Java Ennead Tuple
To search for a value in Ennead Tuple in Java, use the contains() method. The value you want to search is to be set as the parameter of the method. The contains() method returns a Boolean value i.e TRUE if the value exist, else FALSE. Let us first see what we need to work with JavaTuples. To work with Ennead class in JavaTuples, you need to import the following package −import org.javatuples.Ennead;Note − Download JavaTuples Jar library to run JavaTuples program. If you are using Eclipse IDE, then Right Click Project -> Properties -> Java Build Path -> Add External ...
Read MoreComparing dates in MySQL ignoring time portion of a DateTime field?
To compare dates in MySQL except time portion of a datetime field, you can use DATE() function. The syntax is as follows −select *from yourTableName where date(yourColumName) = yourDate;To understand the above concept, let us create a table. The query to create a table is as follows −mysql> create table ComparingDate −> ( −> Name varchar(100), −> Login datetime −> ); Query OK, 0 rows affected (0.50 sec)Now you can insert some records in the table using insert command. The query is as follows −mysql> insert into ComparingDate values('John', '2014-04-06 22:50:45'); Query OK, 1 row affected ...
Read MoreIs MySQL LIMIT applied before or after ORDER BY?
The MySQL LIMIT is applied after ORDER BY. Let us check the limit condition. Firstly, we will create a table −mysql> create table LimitAfterOrderBy −> ( −> Id int, −> Name varchar(100) −> ); Query OK, 0 rows affected (0.50 sec)Insert some records in the table using insert command. The query is as follows −mysql> insert into LimitAfterOrderBy values(101, 'John'); Query OK, 1 row affected (0.18 sec) mysql> insert into LimitAfterOrderBy values(102, 'Carol'); Query OK, 1 row affected (0.15 sec) mysql> insert into LimitAfterOrderBy values(103, 'Bob'); Query OK, 1 row affected (0.21 sec) ...
Read MoreGet timestamp date range with MySQL Select?
To select timestamp data range, use the below syntax −SELECT *FROM yourTableName where yourDataTimeField >= anyDateRange and yourDataTimeField < anyDateRangeTo understand the above syntax, let us create a table. The query to create a table is as follows −mysql> create table DateRange −> ( −> DueTime timestamp −> ); Query OK, 0 rows affected (1.34 sec)Insert some records in the table using insert command. The query is as follows −mysql> insert into DateRange values('2016-11-13'); Query OK, 1 row affected (0.51 sec) mysql> insert into DateRange values('2016-10-14'); Query OK, 1 row ...
Read More8085 Program to convert BCD to HEX
In this program we will see how to convert BCD numbers to binary equivalent.Problem StatementA BCD number is stored at location 802BH. Convert the number into its binary equivalent and store it to the memory location 802CH.DiscussionIn this problem we are taking a BCD number from the memory and converting it to its binary equivalent. At first we are cutting each nibble of the input. So if the input is 52 (0101 0010) then we can simply cut it by masking the number by 0FH and F0H. When the Higher order nibble is cut, then rotate it to the left ...
Read More8085 Program to Exchange 10 bytes
In this program we will see how to exchange a block of 10-byte data using 8085.Problem StatementWrite 8085 Assembly language program to exchange a block of data, where block size is 10.DiscussionThe data are stored at location 8010H to 8019H and 9010H to 9019H. The location 8000H is holding the number of bytes to exchange. In this case number of bytes are 10D so it will be 0AH.The logic is very simple, The HL and DE register pair is pointing the first and second data block respectively. By taking the data we are just swapping the values of each memory ...
Read More8085 Program to convert ASCII to binary
Now let us see a program of Intel 8085 Microprocessor. This program will convert ASCII to binary values.Problem StatementWrite 8085 Assembly language program to convert ASCII to binary or Hexadecimal character values. DiscussionWe know that the ASCII of number 00H is 30H (48D), and ASCII of 09H is39H (57D). So all other numbers are in the range 30H to 39H. The ASCII value of 0AH is 41H (65D) and ASCII of 0FH is 46H (70D), so all other alphabets (B, C, D, E, F) are in the range 41H to 46H.Here the logic is simple. We are checking whether the ASCII ...
