Summary of Session 4- Working with Java Conditional Statements | Java & Selenium | 2024 New series

Summary of Main Ideas

The video focuses on working with Conditional Statements in Java, particularly within the context of programming for Selenium. The instructor explains how Control Statements allow developers to dictate the flow of execution in a program based on certain conditions.

Key Concepts:

Control Statements:
- Control Statements are used to control the execution flow of a program.
- There are three main types of Control Statements in Java:
  - Conditional Statements: Execute specific statements based on conditions.
  - Looping Statements: Repeat a set of statements multiple times.
  - Jumping Statements: Alter the flow of execution (e.g., break, continue).
Types of Conditional Statements:
- If Statement: Executes a block of code if a specified condition is true.
- If-Else Statement: Provides an alternative block of code to execute if the condition is false.
- Nested If-Else Statement: Allows multiple conditions to be checked in a hierarchical manner.
- Switch Case Statement: Simplifies the process of executing code based on multiple potential values of a variable.
Syntax and Examples:
- The instructor provides syntax for various Conditional Statements and demonstrates practical examples using the Eclipse IDE.
- For instance, checking if a person is eligible to vote based on their age using if-else conditions and determining if a number is even or odd.
Best Practices:
- It is recommended to use curly braces for clarity, even for single statements, to avoid errors in complex conditions.
- The use of break in switch statements is emphasized to prevent fall-through behavior, where subsequent cases are executed unintentionally.
Assignments:
- The instructor assigns tasks to reinforce learning, such as finding the largest of two numbers using both if-else conditions and the ternary operator, and reversing the logic of week number outputs.

Methodology / Instructions:

Using If Statements:
```
if (condition) {
    // statements
}
```

Using If-Else Statements:

if (condition) {
    // statements if true
} else {
    // statements if false
}

Using Nested If-Else Statements:

if (condition1) {
    // statements
} else if (condition2) {
    // statements
} else {
    // statements
}

Using Switch Case Statements:

switch (variable) {
    case value1:
        // statements
        break;
    case value2:
        // statements
        break;
    default:
        // statements
}
