In this program we will see how to convert binary numbers to its BCD equivalent.Problem StatementA binary number is store dat location 800H. Convert the number into its BCD equivalent and store it to the memory location 8050H.DiscussionHere we are taking a number from the memory, and initializing it as a counter. Now in each step of this counter we are incrementing the number by 1, and adjust the decimal value. By this process we are finding the BCD value of binary number or hexadecimal number.We can use INRinstruction to increment the counter in this case but this instruction will ... Read More

The method java.io.File.equals() is used to find if the two file names refer to the same File in Java. This method requires a single parameter i.e.the file object that is to be compared to the other file object. It returns if the file objects are same and false otherwise.A program that demonstrates this is given as follows −Example Live Demoimport java.io.File; public class Demo { public static void main(String[] args) { try { File file1 = new File("demo1.txt"); File file2 = new File("demo2.txt"); boolean flag ...

Firstly, create a Formatter and Calendar object.Formatter f = new Formatter(); Calendar cal = Calendar.getInstance();Now display the current date and time. We have shown the date here in both lowercase and uppercase −f = new Formatter(); System.out.println(f.format("Date and Time (lowercase): %tc", cal)); f = new Formatter(); System.out.println(f.format("Date and Time (uppercase): %Tc", cal));The following is an example −Example Live Demoimport java.util.Calendar; import java.util.Formatter; public class Demo { public static void main(String args[]) { Formatter f = new Formatter(); Calendar cal = Calendar.getInstance(); ...

The method pathCompinent() is used to remove the file information from a filename and return only its path component. This method requires a single parameter i.e. the file name and it returns the path component only of the file name.A program that demonstrates this is given as follows −Example Live Demoimport java.io.File; public class Demo { public static String pathComponent(String fname) { int pos = fname.lastIndexOf(File.separator); if (pos > -1) return fname.substring(0, pos); else return fname; } public static void main(String[] ...
