OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
Step by step

- Exercise (5): Strings A. String Length method public class MyClass { public static void main(String[] args) { String txt = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"; System.out.println("The length of the txt string is: " + txt.length()); ) } B. Uppercase and Lowercase methods public class MyClass { public static void main(String[] args) { String txt = "Hello World"; System.out.println(txt.toUpperCase ()); // Outputs "HELLO WORLD" System.out.println(txt.toLowerCase ()); // Outputs "hello world" }} C. String concatenation The + operator can be used between strings to combine them. This is called concatenation. You can also use the concat() method to concatenate two strings public class MyClass { public static void main(String[] args) { String firstName = "Amani"; String fatherName = "Sabri"; + fatherName); System.out. println(firstName + System.out.println(firstName.concat (fatherName)); }} 1.
