JavaFor Loop Examples
Real-Life Examples
To demonstrate a practical example of thefor loop, let's create a program that counts to 100 by tens:
In this example, we create a program that only print even values between 0 and 10:
And in this example, we create a program that prints the multiplication table for a specified number:
Example
int number = 2;// Print the multiplication table for the number 2for (int i = 1; i <= 10; i++) { System.out.println(number + " x " + i + " = " + (number * i));}Here is a simple program that prints the seat numbers in a theater row:
Example
for (int seat = 1; seat <= 5; seat++) { System.out.println("Seat number: " + seat);}Use a loop to calculate the factorial of a given number:
Example
int n = 5;int fact = 1;for (int i = 1; i <= n; i++) { fact *= i;}System.out.println("Factorial of " + n + " is " + fact);// Output: Factorial of 5 is 120Factorial means multiplying a number by every number below it, down to 1. For example, the factorial of 5 is: 5 * 4 * 3 * 2 * 1 = 120
