8085 program to find the set bit of accumulator
Here we will see how to find the place of the set bit of the Accumulator data.Problem StatementWrite 8085 Assembly language program to find the position where the bit is 1. In the accumulator all bits are 0, but only one bit is 1. We have to get the position of the bit which is 1. The position will be displayed in decimal from 1 to 8.DiscussionWe are taking the number like (0010 0000). The place value is 6. So we are rotating the number to the right through carry. If the carry bit is 1, then we break the ...
Read MoreMySQL query to select all fields beginning with a given number with next character a letter?
You can use REGEXP for this. Let us first create a table −mysql> create table DemoTable ( Value text ); Query OK, 0 rows affected (1.28 sec)Insert records in the table using insert command −mysql> insert into DemoTable values('645st'); Query OK, 1 row affected (0.25 sec) mysql> insert into DemoTable values('765stp'); Query OK, 1 row affected (0.14 sec) mysql> insert into DemoTable values('665tcp'); Query OK, 1 row affected (0.21 sec) mysql> insert into DemoTable values('606cpp'); Query OK, 1 row affected (0.14 sec)Display all records from the table using select statement −mysql> select * from DemoTable;This will produce ...
Read MoreHow to add JTable to Panel in Java Swing?
To add JTabel to Panel, let us first crerate a panel −JPanel panel = new JPanel();Now, create JTable and add rows and columns with the records −String[][] rec = { { "1", "Steve", "AUS" }, { "2", "Virat", "IND" }, { "3", "Kane", "NZ" }, { "4", "David", "AUS" }, { "5", "Ben", "ENG" }, { "6", "Eion", "ENG" }, }; String[] header = { "Rank", "Player", "Country" }; JTable table = new JTable(rec, header);Add the above created table to panel −panel.add(new JScrollPane(table));The following is an example to add JTabel to Panel in Java ...
Read More8086 program to determine squares of numbers in an array of n numbers
In this program we will see how to find the squares of n numbers stored in an array.Problem StatementWrite 8086 Assembly language program to calculate square of each numbers stored in an array of size n. The array size is stored at location offset 600, and Numbers are stored at 601 onwards.DiscussionTo solve this problem, we are taking the size of the array into the CL register, and make CH = 00H for counting. Now from each location take the number into accumulator, to make square, we have to multiply it two times. so we are multiplying AL with AL. ...
Read More8085 program to subtract two BCD numbers
Here we will see how to perform BCD subtractions using 8085.Problem StatementWrite 8085 Assembly language program to perform BCD subtractions of tow numbers stored at location 8001 and 8002. The result will be stored at 8050 and 8051.DiscussionTo subtract two BCD numbers, we are going to use the 10s complement method. Taking the first number and storing into B, Load 99 into A then subtract the number to get the 9’s complement. After that add 1 with the result to get 10’s complement. We cannot increase using INR instruction. This does not effect on CY flag. So we have to ...
Read More8086 program to generate Fibonacci Sequence
Here we will see how to generate Fibonacci sequence using 8086Problem StatementWrite 8086 Assembly language program to generate Fibonacci sequence. The limit of the sequence is stored at location offset 500. The item will be stored from offset 600 onwards.DiscussionTo generate Fibonacci sequence, we are putting the 00H and 01H into memory at first. Then we are taking the limit from location offset 500. The limit is decreased by 2 at first, because 00H and 01H is already present there. Now we are taking number from previous location, then add it with the value of current location, after that storing ...
Read MoreHow to validate expiry date on a MySQL query?
You can use NOW() for this. Following is the syntax −select * from yourTableName where yourColumnName> now();Let us first create a table −mysql> create table DemoTable ( Id int NOT NULL AUTO_INCREMENT PRIMARY KEY, expiryDateOfMedicine datetime ); Query OK, 0 rows affected (0.55 sec)Insert records in the table using insert command −mysql> insert into DemoTable(expiryDateOfMedicine) values('2019-04-27 11:29:00'); Query OK, 1 row affected (0.36 sec) mysql> insert into DemoTable(expiryDateOfMedicine) values('2019-04-26 10:39:21'); Query OK, 1 row affected (0.41 sec) mysql> insert into DemoTable(expiryDateOfMedicine) values('2019-04-28 11:30:10'); Query OK, 1 row affected (0.18 sec) mysql> insert into DemoTable(expiryDateOfMedicine) values('2019-04-29 12:44:11'); ...

In this program we will see how to reverse an 8-bit number using 8-bit operation.Problem StatementWrite 8086 Assembly language program to reverse an 8-bit number which is stored at location 2000, using 8-bit operations.Discussion8086 has 8-bit operation for rotation. we are taking the byte from 2000. Then rotate that byte with ROL instruction. After that put the number into memory in reverse form.InputAddressData……2000AB…… Flow Diagram ProgramOutputAddressData……2000BA……
Read MoreHow to create a Box to display components from left to right in Java
Box is lightweight container that uses a BoxLayout object as its layout manager. To display components from left to right, use Box createHorizontalBox() method.Let us first create some button components −JButton button1 = new JButton("One"); JButton button2 = new JButton("Two"); JButton button3 = new JButton("Three"); JButton button4 = new JButton("Four"); JButton button5 = new JButton("Five"); JButton button6 = new JButton("Six");Now, crate a Box and align all the buttons from left to right −Box box = Box.createHorizontalBox(); box.add(button1); box.add(button2); box.add(button3); box.add(button4); box.add(button5); box.add(button6);The following is an example to create a Box to display components from left to right −Examplepackage my; import ...
Read More8085 program with a subroutine to add ten packed BCD numbers.
Here we will see how to add ten packed BCD numbers using 8085.Problem StatementA set of ten packed BCD numbers is stored in the memory location starting from 8040H to 8049H.Write a program with a subroutine to add these numbers in BCD. If a carry is generated save it to register B, and adjust it to BCD. The final sum will be less than 9999BCD. Store the sum at locations 8060H and 8061H.Write a second subroutine to unpack the BCD sum stored in registers A and B, and store them in the OutputBuffer memory starting at 8062H.
