Java Programming Language

Java Programming Language

we will cover the entire Java programming language starting from basic installation to advanced programming concepts. This video is for all students who are starting out in the world of coding and programming, or who know languages like C or Python and want to learn Java. After watching this video, you will be able to apply many concepts and code using Java and even create a mini-project using the concepts you have learned. We hope this course helps you learn Java and apply your knowledge to real-world projects.

We have already created a course with over 200 videos on C programming, and a web development course where we covered HTML, CSS, and JavaScript. We will also provide notes at the end of the video that you can use as a reference to learn about the technologies you are interested in learning. For these technologies, you can refer to those courses.

Java Extension and Java Class

In Java, an extension is represented by a Java file. Within this file, there is a Java class with some code that represents a function. A function in Java is a block of code that performs a specific task that is important. We are happy to provide a guide to all Java programming and Java. We hope to help students learn about Java and learn more about the language that we are comfortable with using Java. You can also use Java programming. We will be happy to share your knowledge of Java and our knowledge.

In Java, a function is a block of code that performs a specific task, such as pressing the volume button on a phone increases its volume. The syntax for printing to the console is System.out.println in Java. Semicolons are used to indicate the end of a line of code, just like a period at the end of a sentence in English. In Java, we use types to indicate what kind of variable we are creating, whether it is a name, character, or a number, we are using a type of variable.

Primitive and Non-Primitive Types

The primitive types include byte, short, int, long, float, double, char, and boolean. The primitive types are used for simple values, and a type such as age with a type like age with the type of age with an age. The type of variables and a number that is a number is a type of string, or a string number.

Non-primitive types include String, which is a collection of characters to form a word or sentence. The length of a primitive type is fixed and within the byte range of 128 to 127, we can store any number. If we have a variable of reference type, we can store as many characters as we want without getting an error, as long as we don't exceed the available memory. We will discuss this in more detail later on.

New Keyword and Length Function

We will use the new keyword to declare non-primitive or reference types. Using the new keyword when we use it to create an instance of a class. To print the length of the name variable, we can use the length function by typing name.length.

To assign a value such as true or false to a variable called isAdult, we can use a type of boolean. To assign a number such as a value to a variable, we use the type of the variable. To write a string to a string, we use a new type to read the length and read a new name to read the string. We have a new value, we need to use the type to read and write the new name length. We should use the name.length to provide a new message and identify a new object.

Introduction to Java

Java is a zero-indexed language, meaning positions start from zero and not one.

We can assign a string to a variable and then use that variable to manipulate the string. We will use the "new String" keyword to avoid errors in our code when we don't use it.

The `charAt` function allows us to access the first position of the string and which character is stored at which position is present. The `length` of a string is the number of characters in the string. We can replace any character with another character at that position.

Strings in Java are immutable, which means once you have created a string inside Java, you cannot change it. If you want to change it, then you will have to create a new string.

Manipulating Strings

The `subString` method is used to return a new string that is a substring of the original string. It takes two parameters: starting index and ending index.

The `length` function is used to find out the number of characters in our own string. We will also use this function to replace the length. It is a function to remove any character from the original string.

Arrays in Java

If we want to store the marks of three subjects, then we need to create an array with three memory locations in which we can store the values of int type.

The first function of two important functions of arrays is `length`. If we want the length of a list of an array, then we can get it. Along with that, we have an important function `sort`. If we want to sort a list, then we write a function `sort`.
