8085 program to count number of elements which are less than 0A
In this section we will count elements which are lesser than 0AH using 8085.problem StatementThere is an array of some elements. Write 8085 Assembly language program to count number of elements that are lesser than 0AH.DiscussionThe array is placed at location F051H onwards. The F050 is holding the size of the array. The logic is simple. At first we will take the array size into the B register. The C register will count number of elements less than 0AH. We will take numbers one by one from memory, then compare it with 0A. if the CY flag is set it ...
Read MoreHow to create a horizontal slider with custom min, max, and initial value in Java
While creating horizontal slider, we can set custom values as well. Let us take three integer variable and set the int values for min, max as well as the initial value of the slider −int val = 75; int min = 0; int max = 100;Set it to the slider while creating a new slider. Here, we have set the constant to be HORIZONTAL, since we are creating a horizontal slider −JSlider slider = new JSlider(JSlider.HORIZONTAL, min, max, val);The following is an example to create a horizontal slider with custom min, max and initial value −Examplepackage my; import java.awt.Color; import ...
Read MoreDisplay only the horizontal scrollbar in Java
To display only the horizontal scrollbar, use the VERTICAL_SCROLLBAR_NEVER constant, which eventually displays only the horizontal scrollbar.The following is an example to display only the horizontal scrollbar in Java −Examplepackage my; import java.awt.BorderLayout; import java.awt.Dimension; import javax.swing.Box; import javax.swing.JButton; import javax.swing.JFrame; import javax.swing.JScrollPane; public class SwingDemo { public static void main(String args[]) { JFrame frame = new JFrame("Demo"); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); JButton button1 = new JButton("Online Compiler"); JButton button2 = new JButton("Quiz"); JButton button3 = new JButton("Questions and Answers"); JButton button4 = new ...
Read More8085 program to find the element that appears once
In this program we will see how to find a number who appears only once in an array of elements.Problem StatementWrite 8085 Assembly language program to find a number who appears only once in an array of elements. The size of the array is stored at location F100; the numbers are stored from memory location F101 onwards. The result will be stored at F150.DiscussionThe logic behind this problem is simple. Though it may find some wrong results in some cases. It can find the number if there is only one number which is appeared once, and rest of the numbers ...
Read More8085 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 ...
