Iterative constructs in Java!
Introduction
Introduction to Loops
Loops, also known as iterative statements, are fundamental control flow structures in Java that allow a block of code to be executed repeatedly. They automate repetitive tasks, making programs more efficient and concise.
Types of Loops in Java
Java provides three main types of loops:
For Loop
While Loop
Do-While Loop
For loop:
For Loop
The for loop is a versatile loop structure well-suited for situations where the number of iterations is known in advance.
Syntax:
for (initialization; condition; updation) {
// Statements to be executed
}
Components:
Initialization: This statement initializes the loop counter variable. It is executed only once at the beginning of the loop.
Condition: This boolean expression is evaluated before each iteration. If the condition is true, the loop body is executed. If it is false, the loop terminates.
Updation: This statement updates the loop counter variable after each iteration. It typically increments or decrements the counter.
Example:
for (int i = 1; i <= 10; i++) {
System.out.println(i);
}
This loop prints numbers from 1 to 10. int i = 1 initializes the loop counter i to 1. The loop continues as long as i <= 10. After each iteration, i is incremented by 1 using i++.

Entry-controlled loops, like the for loop, evaluate the test expression before executing the loop's body. If the condition is initially false, the loop body is skipped entirely, ensuring no unnecessary executions occur.
The for loop in Java consists of initialization, condition, and increment/decrement statements, all within parentheses. This structure makes it ideal when the number of iterations is known beforehand, promoting code readability.
In contrast to exit-controlled loops (e.g., do-while), entry-controlled loops offer a safeguard against executing code with invalid initial conditions. This characteristic enhances program robustness and prevents potential errors.
