8086 program to multiply two 16-bit numbers
In this program we will see how to multiply two 16-bit numbers.Problem StatementWrite 8086 Assembly language program to multiply two 16-bit number stored in memory location 3000H – 3001H and 3002H – 3003H.DiscussionWe can do multiplication in 8086 with MUL instruction. For 16-bit data the result may exceed the range, the higher order 16-bit values are stored at DX register.We are taking two numbers BCAD * FE2D = 1BADAInputAddressData……3000AD3001BC30022D3003FE…… Flow Diagram Program OutputAddressData……3004693005D03006543007BB……
Read MoreThe setAtX() method of the Decade Tuple in Java
The setAtX() method is used to set a new value in the Decade Tuple. Here, X is the index wherein you want to set the value. For example, setAt5() sets the value at index 5. The value to be included is to be set as the value in the parameter, likesetAt5(“Katie”);Let us first see what we need to work with JavaTuples. To work with Decade class in JavaTuples, you need to import the following packageimport org.javatuples.Decade;Note: Download JavaTuples Jar library to run JavaTuples program. If you are using Eclipse IDE, then Right Click Project -> Properties -> Java Build Path ...
Read MoreHow to create a common error page using JSP?
JSP gives you an option to specify Error Page for each JSP using page attribute. Whenever the page throws an exception, the JSP container automatically invokes the error page.Following is an example to specifiy an error page for a main.jsp. To set up an error page, use the directive. Error Handling Example We will now write one Error Handling JSP ShowError.jsp, which is given below.

Read MoreApply MySQL query to each table in a database?
To apply MySQL query to each table in a database, you can use INFORMATION_SCHEMA.TABLES. Following is the syntax −SELECT SUM(TABLE_ROWS) AS anyAliasName FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_SCHEMA=yourDatabaseName;Let us implement the above syntax to query each table in a database.mysql> SELECT SUM(TABLE_ROWS) AS Total FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_SCHEMA= DATABASE();This will produce the Following output −+-------+ | Total | +-------+ | 1666 | +-------+ 1 row in set (0.01 sec)
Read MoreUse MySQL concat() and lower() effectively
The contact() method is used to concatenate. However, lower() is used to change the case to lowercase. For our example, let us create a table.The query to create a table is as followsmysql> create table concatAndLowerDemo -> ( -> FirstValue varchar(10), -> SecondValue varchar(10), -> ThirdValue varchar(10), -> FourthValue varchar(10) -> ); Query OK, 0 rows affected (0.55 sec)Now you can insert some records in the table using insert command.The query is as followsmysql> insert into concatAndLowerDemo values('John', '12345', 'Java', 'MySQL'); Query OK, 1 row affected (0.21 sec) mysql> insert into concatAndLowerDemo values('Hi', '12345', ...
Read More8086 program to find average of n numbers
In this program we will see how to find the average of n numbers in a given series.Problem StatementWrite 8086 Assembly language program to find the average of n numbers stored in a given series starts from memory offset 501. The size of the series is stored at memory offset 500.DiscussionTo do this task we are initializing the Source Index (SI) register to the starting address of the series. We are also taking the series size into CL. The CL will be used as counter. To store add we are using AL register. Initially set AL to 0. In each ...
Read MoreBulk change all entries for a particular field in MySQL?
Let us first create a demo table −mysql> create table BulkChangeDemo -> ( -> CustomerId int NOT NULL AUTO_INCREMENT PRIMARY KEY, -> CustomerName varchar(20), -> isEducated boolean -> ); Query OK, 0 rows affected (1.47 sec)Insert some records in the table using insert command. The query is as follows −mysql> insert into BulkChangeDemo(CustomerName, isEducated) values('Larry', true); Query OK, 1 row affected (0.09 sec) mysql> insert into BulkChangeDemo(CustomerName, isEducated) values('John', false); Query OK, 1 row affected (0.16 sec) mysql> insert into BulkChangeDemo(CustomerName, isEducated) values('Carol', false); Query OK, 1 row affected (0.25 sec) mysql> insert into BulkChangeDemo(CustomerName, ...
Read MoreWrite a MySQL query where length of the records is longer than 1?
Here, we will use OCTET_LENGTH to check the length of a record since we want the records with length more than 1. Let us first create a table −mysql> create table DemoTable ( UserId int NOT NULL AUTO_INCREMENT PRIMARY KEY, UserName varchar(20), UserGender varchar(20) ); Query OK, 0 rows affected (0.55 sec)Insert some records in the table using insert command −mysql> insert into DemoTable(UserName, UserGender) values('John', 'M'); Query OK, 1 row affected (0.82 sec) mysql> insert into DemoTable(UserName, UserGender) values('Carol', 'Male'); Query OK, 1 row affected (0.21 sec) mysql> insert into DemoTable(UserName, UserGender) values('Mia', 'Female'); Query OK, ...
Read MoreWhat are important server response headers that are useful in web programming?
Following is a summary of the most useful HTTP 1.1 response headers which go back to the browser from the web server. These headers are frequently used in web programming −Sr.No.Header & Description1AllowThis header specifies the request methods (GET, POST, etc.) that the server supports.2Cache-ControlThis header specifies the circumstances in which the response document can safely be cached. It can have values public, private or no-cache etc. Public means document is cacheable, Private means document is for a single user and can only be stored in private (nonshared) caches and no-cache means document should never be cached.3ConnectionThis header instructs the ...
Read MoreSubtract content of two ports by interfacing 8255 with 8085 microprocessor
In this program we will see how to perform subtraction by using ports to take data and send the result into the port.Problem StatementWrite 8085 Assembly language program for interfacing between 8085 and 8255. Here Port A and Port B are holding two values, take the numbers from port A and B, subtract B from A, and send the result at port C.DiscussionThe task is very simple. At first we have to setup the control word register of 8255 chip. After that we will take the input from port A and B, add the content, and send it to port ...
