Control flow structures allow us to make decisions, repeat actions, and control the flow of our programs. Java provides several control flow statements, including if-else statements, loops, and switch statements.
Let's explore each of the Control Flow in detail.
Element 1: If-Else Statements
The if-else statement is used to make decisions in our programs based on conditions. It allows us to execute a block of code if a condition is true and another block of code if the condition is false. Let's take a look at an example:
Element 2: Loops
Loops are used to repeat a block of code multiple times. Java provides three types of loops: the while loop, the do-while loop, and the for loop.
Element 2.1: While Loop
The while loop repeatedly executes a block of code as long as a condition is true.
Here's an example:
Element 2.2: Do-While Loop
The do-while loop is similar to the while loop, but it executes the block of code at least once before checking the condition. Here's an example:
Element 2.3: For Loop
The for loop provides a compact way to iterate over a range of values. It consists of an initialization, a condition, and an increment or decrement.
Here's an example:
Element 3: Switch Statements
Switch statements are used to perform different actions based on different values of a variable or an expression. They provide an alternative to long chains of if-else statements.
Here's an example:
