Nested if and Multi-Way if-else Statements

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...

Two-Way if-else Statements

Two-Way if-else Statements:           An if-else statement allows a program to choose between two different execution paths based on whether a condition is true or false.           While a one-way if statement performs an action only when the specified condition is true, a two-way if-else statement provides alternative actions to be taken depending on whether the condition is true or false.           The syntax for a two-way if-else statement is as follows: if (boolean-expression) {     statement(s)-for-the-true-case; } else {     statement(s)-for-the-false-case; }           The flowchart of this statement is depicted in Figure -1.    Figure-1              Figure-1 An if-else statement executes statements for the true case if the Boolean expression evaluates to true; otherwise, statements for the fal...

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...
