A pathname can be either absolute or relative.           📝Once you have File object in hand, then there is a list of helper methods which can be used to manipulate the files.        Eg:  public String getName()           public String getParent()           public File getParentFile()       public String getPath()          public boolean isAbsolute() ... and etc.     import java.io.*;      public class LearnTcode {          public static void main(String[] args) {                    try {                  File file = new File("learnTocode.txt");                  if (file.createNewFile()) {                      System.out.println("Join our channel");                  } else {                      System.out.println("File already exists.");                  }              } catch (IOException e) {                  e.printStackTrace();              }                }      }  //output is:   ------------

-----------🧑‍💻🧑‍💻🧑‍💻🧑‍💻🧑‍💻JAVA🧑‍💻🧑‍💻🧑‍💻🧑‍💻🧑‍💻🧑‍💻---------- LESSON 10:- INHERITANCE ⚜️Inheritance is one of the basic concept in object orientation in which a new class is created by absorbing an existing class’s members and embellishing them with new or modified capabilities. ✅ The existing class is called the superclass, and the new class is the subclass. Syntax for inheritance class SubClassName extends SuperClassName{}; Why And When To Use "Inheritance"? - It is useful for code reusability: reuse attributes and methods of an existing class when you create a new class. Let's explore by using sample code:- class Vehicle { protected String brand = "Ford"; // Vehicle attribute public void honk() { // Vehicle method System.out.println("Tuut, tuut!"); } } class Car extends Vehicle { private String modelName = "Mustang"; // Car attribute public static void main(String[] args) { // Create a myCar object Car myCar = new Car(); // Call the honk() method (from the Vehicle class) on the myCar object myCar.honk(); // Display the value of the brand attribute (from the Vehicle class) and the value of the modelName from the Car class System.out.println(myCar.brand + " " + myCar.modelName); } } "thanks all!🙏" https://t.me/Africacoder

----🧑‍💻🧑‍💻🧑‍💻🧑‍💻🧑‍💻🧑‍💻🧑‍💻JAVA🧑‍💻🧑‍💻🧑‍💻🧑‍💻🧑‍💻----- LESSON 9: POLYMORPHISM The word polymorphism means having many forms. In simple words, we can define polymorphism as the ability of a message to be displayed in more than one form. Types of polymorphism In Java , polymorphism is mainly divided into two types: i.Compile-time Polymorphism 💎This type of polymorphism is achieved by function overloading or operator overloading. But Java doesn’t support the Operator Overloading. ii.Runtime Polymorphism ❤️‍🔥It is a process in which a function call to the overridden method is resolved at Runtime. This type of polymorphism is achieved by Method Overriding. >💗 Java program to demostrate polymorphism class Parent { // Method of parent class void Print() { // Print statement System.out.println("parent class"); } } // Helper class class subclass2 extends Parent { // Method void Print() { // Print statement System.out.println("subclass2"); } } // Class 4 // Main class class GFG { // Main driver method public static void main(String[] args) { // Creating object of class 1 Parent a; // Now we will be calling print methods // inside main() method a = new subclass1(); a.Print(); } } https://t.me/Africacoder 😊

C++ LESSON 8: ✍🏻✍🏻......🌿🌿🌿......✍🏻✍🏻   Break and continue statement ➾there are two statements break; and continue; ➾it is desirable to skip the execution of a loop for a certain test condition or terminate it immediately without checking the condition.     🌿🌿⓵.break statement 🌿🌿 ➾is used to break loop or switch statement ➾. It breaks the current flow of the program at the given condition ➾In case of inner loop, it breaks only inner loop. ➾break statement is almost always used inside the body of conditional statement inside the loop. 🌿🌿⓶.Continue Statement 🌿🌿 ➾to skip a certain test condition within a loop ➾ It continues the current flow of the program and skips the remaining code at specified condition ➾ It is almost always used inside a conditional statement.
