Nested if and Multi-Way if-else Statements

-
Image
Nested if and Multi-Way if-else Statements:           An if statement can be nested inside another if statement, forming a nested if statement. This allows for more complex decision-making in a program.           In a nested if statement, an if statement is placed inside another if statement. The inner if statement is considered to be nested within the outer if statement. There is no limit to the depth of nesting and an inner if statement can also contain another if statement.           Here is an example of a nested if statement: if (i > k) {     if (j > k)         System.out.println("i and j are greater than k"); } else {     System.out.println("i is less than or equal to k"); }           In this example, the inner if statement ` if (j > k) ` is nested inside the outer if statement ` if (i > k) `. This allows for di...

The Java Language Specification, API, JDK, and IDE

-
Image
Java Language Specification: The Java Language Specification (JLS) is a document that defines the syntax, semantics, and rules of the Java programming language. It provides a comprehensive guide for developers and compiler writers to understand how Java programs should be written and interpreted. The JLS covers topics such as data types, variables, expressions, control flow, object-oriented programming concepts, exception handling, and more. It serves as a standard reference for ensuring consistent behavior across different Java implementations. Java API: The Java API (Application Programming Interface) is a collection of pre-written classes and interfaces that provide ready-to-use functionality for Java developers. The API is organized into packages, each containing related classes and interfaces. These packages cover a wide range of areas such as input/output operations, networking, GUI programming, database access, multithreading, and many others. By utilizing the Java API, develope...

History of The Java

   History of The Java:            Java was developed by a team led by James Gosling at Sun Microsystems. Sun Microsystems was purchased by Oracle in 2010. Originally called Oak, Java was designed in 1991 for use in embedded chips in consumer electronic appliances. In 1995, renamed Java, it was redesigned for developing Web applications.             Java has become enormously popular. Its rapid rise and wide acceptance can be traced to its design characteristics, particularly its promise that you can write a program once and run it anywhere. As stated by its designer, Java is simple, object oriented, distributed, interpreted, robust, secure, architecture neutral, portable, high performance, multithreaded, and dynamic           Java is a full-featured, general-purpose programming language that can be used to develop robust mission-critical applications. Today, it is em...

If statements

 If statements:           An if statement is a programming construct that allows a program to choose between different paths of execution based on a specified condition. In the previous program, a message like "6 + 2 = 7 is false" is displayed. If you want the message to be "6 + 2 = 7 is incorrect," you can use a selection statement to make this minor modification.           In Java, there are several types of selection statements available: one-way if statements , two-way if-else statements, nested if statements, multi-way if-else statements , switch statements, and conditional expressions.           A one-way if statement is used to execute a block of code only if a certain condition is true. The syntax for a one-way if statement is as follows: if (boolean-expression) {     statement(s); }           The flowchart in Figure-1a visually represents how J...
