if-else statements

-

 In Java, the if-else statement is used to make decisions in a program. It allows the program to execute different code depending on whether a certain condition is true or false. The basic structure of an if-else statement is as follows: 

The condition is a boolean expression that evaluates to either true or false. If the condition is true, the code inside the first set of curly braces will be executed, otherwise the code inside the second set of curly braces will be executed.

Here's an example of an if-else statement in Java:

In this example, the program checks the value of the variable age against the value 18. If the value of age is greater than or equal to 18, the program will execute the first block of code and print "You are an adult." to the console. Otherwise, the program will execute the second block of code and print "You are not an adult." to the console.

You can also use the if statement without the else part, it will execute the code inside the if statement only if the condition is true:

You can also chain multiple if-else statements together to create more complex decision-making logic by using else if

As a new programmer, it's important to practice using if-else statements to become comfortable with making decisions in your code and to learn how to use them to create more complex logic.

Getting Started with the Java Flow API

-
Exploring the Java Flow API The Java Flow API, introduced in Java 9, provides a standard and efficient way for components of a reactive system to communicate with each other asynchronously, without requiring them to know each other's implementation details. In this post, we'll explore the key components of the Flow API and show how to use them to implement the Observer pattern in a more standardized way. Key Components of the Flow API The Flow API defines four key components: Publisher , Subscriber , Subscription , and Processor . Publisher A Publisher is a provider of data items, which publishes them to one or more Subscriber instances. To implement a custom Publisher, you need to implement the java.util.concurrent.Flow.Publisher interface, which defines the following methods: subscribe(Subscriber<? super T> subscriber) : Subscribes a Subscriber to this Publisher , returning a new Subscription instance that represents the connection between them. S...

Loops in Java 8

-
Java 8 introduces a number of new features for loops, including the forEach() method and the Stream API. The forEach() method is a great way to iterate over a collection without having to worry about keeping track of the index. It is also more efficient than using a for loop. The Stream API is a new way of working with collections, and it provides a number of new features and benefits. One of the benefits of the Stream API is that it can be used to perform parallel processing. These are just a few of the new features of Java 8 loops. If you are using Java 8, I encourage you to explore the new features and see how they can be used to improve your code. Here is an example of how to use the forEach() method to print out all of the elements in a List: List list = Arrays.asList("Hello", "World"); list.forEach(System.out::println); Here is an example of how to use the Stream API to perform parallel processing: List list = Arrays....

switch case in java

-
The switch statement in Java is a control flow statement that allows you to test a variable or an expression against multiple cases. It's similar to the if-else statement, but it can be a more convenient and efficient way to handle multiple conditions. The basic structure of a switch statement is as follows:  The expression is the variable or expression that you want to test. The case statement is followed by a value or an expression, and the code that follows the case statement will be executed if the expression matches that value. The break statement is used to exit the switch statement and prevent the execution of the next case.   Here's an example of a switch statement in Java:  In Java 8, the switch statement was enhanced to support lambda expression as well. It allows you to use a functional interface inside the case statement, which makes the switch statement more powerful. Here's an example of how you can use a lambda expression in a switch statement...
