First, create a TreeSet and add elements to it −TreeSet set = new TreeSet(); set.add("65"); set.add("45"); set.add("19"); set.add("27"); set.add("89"); set.add("57");Now, sort it in ascending order, which is the default −Iterator i = set.iterator(); while(i.hasNext()){ System.out.println(i.next()); }If you want to sort in descending order, then use the descendingIterator() method −Iterator j = set.descendingIterator(); while(j.hasNext()) { System.out.println(j.next()); }The following is an example to sort items in a TreeSet in ascending and descending order −Example Live Demoimport java.util.*; public class Demo { public static void main(String args[]){ TreeSet set ...

The method java.io.File.getAbsoluteFile() can be used to acquire the absolute filename path from a relative filename path in Java. This method requires no parameters. It returns the file that is defined by the path name.A program that demonstrates this is given as follows −Example Live Demoimport java.io.File; public class Demo { public static void main(String[] argv) throws Exception { File file = new File("demo1.txt"); file = file.getAbsoluteFile(); System.out.println(file); } }The output of the above program is as follows −Outputc:\JavaProgram\demo1.txtNow let us understand the above program.The method java.io.File.getAbsoluteFile() is used to ...

In this program we will see how to sort a block of bytes in descending order using bubble sorting technique.Problem StatementWrite8085 Assembly language program to sort numbers in descending order where n number of numbers are stored in consecutive memory locations starting from 8041H and the value of n is available in memory location 8040H (Using BUBBLE sort).DiscussionIn this program we will arrange the numbers in bubble sorting technique. In this sorting technique, it will be executed in different pass. In each pass the smallest number is stored at the end of the list. Here we are taking the numbers ... Read More
