Code:- import java.io.*; import java.nio.file.*; import java.util.*; public class Delete {     Scanner scan = new Scanner(System.in);     String pth;     char ch;     boolean empty;     public void input() {         try {             System.out.printf("PATH: ");             pth = scan.nextLine();         } catch (InputMismatchException e) {             System.err.println("Error Occur!\n" + e.getMessage());             System.exit(0);   ...

The following code is to copy the file from the source to destination and replace if already exists. Code:- import java.nio.file.*; import java.util.*; import java.nio.file.CopyOption.*; public class Copy {     String spth, tpth;     Path source, target;     Scanner scan = new Scanner(System.in);     public void input() {         try {             System.out.printf("SOURCE: ");             spth = scan.nextLine();             System.out.printf("TARGET: ");             tpth = scan.nextLine();         } catch (InputMismatchException e) {             System.err.println("Error Occur!\n" ...

The following code is to create a new text file and save some text in it and then give user the choice either to open the file at the same time or not. (File will be opened using MS Word from its default directory) Code:- import java.io.*; import java.nio.file.*; import java.util.*; public class Files {     static Process Microsoft;     Path path;     @SuppressWarnings("ResultOfObjectAllocationIgnored")     public void file(String pth) throws IOException {         path = Paths.get(pth);         if (!path.toFile().exists()) {             new java.io.File(path.toString()).createNewFile();             writeData(path.toString());         } else {             S...

Swapping is the main feature of both the sorting techniques. You must understand the swapping of elements from one index position to another in order to make easier for you to understand the Sorting Techniques . Example:- Before you learn about swapping the values within the Array List , you should learn the simple swapping within two or more variables. int a=10, b=20; Now, to do swapping we need an extra variable. int temp; temp=a; a=b; b=temp; Now, the identifier ‘a’ has the integer value ‘20’ and the identifier ‘b’ has the integer value ‘10’. Step 1: temp=a; By the above step, we have stored the integer value ‘10’ in the identifier ‘temp’. To make it easier just think like this: temp=10; Step 2: a=b; By the above step, we have stored the integer value ‘20’ in the identifier ‘a’. To make it easier just think like this: a=20; Step 3: b=temp; Now, the identifier ‘temp’ has the integer value ‘10’. So, by the above step we have changed the value of ‘b’ i.e., fro...
