8085 program to check whether both the nibbles of 8 bit number are equal or not
Here we will see how to check whether two nibbles of a number are same or not.Problem StatementWrite 8085 Assembly language program to check whether upper nibble and lower nibbles are same or not.DiscussionTo check the nibbles, we have to mask at first. So we need to mask the lower nibble and upper nibble and store them into different registers. The upper nibble will be shifted to the right four bits to make it lower nibble. Then we can check both are same or not. If they are same store 00 at F150 location, otherwise store FF at F150 location.InputAddressDataF050FE AddressDataF050AA Flow ...

This is a C++ program to find the Mode in a data set.AlgorithmsBegin function insertinset() to insert data in the set. Create newnode and temp(t) node. Node to be inserted in the list using newnode. If head is null then assign new node to head and increase the count. During insertion perform insertion sort for sorting data. If the newnode->data is equal to any of the element present in the set, then just increment count. EndExample#include using namespace std; struct set // a structure set to declare ...

Use SpinnerNumberModel to create a spinner with value as numbers −SpinnerModel value = new SpinnerNumberModel(10, 0, 20, 1);Now set the values −JSpinner spinner = new JSpinner(value);The following is an example to create a JSpinner with values as numbers −Examplepackage my; import java.awt.Font; import javax.swing.*; public class SwingDemo { public static void main(String[] args) { JFrame frame = new JFrame("Spinner Demo"); SpinnerModel value = new SpinnerNumberModel(10, 0, 20, 1); JSpinner spinner = new JSpinner(value); spinner.setBounds(50, 80, 70, 100); frame.add(spinner); frame.setSize(550,300); frame.setLayout(null); frame.setVisible(true); } }This will produce the following output −
Read More8085 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 ...
