Java For Loop: Your Key to Efficient Iteration

In Java, the for loop is a control flow statement that allows you to execute a block of code a specific number of times. It consists of three parts: the loop initialization, the condition, and the iteration expression. The for loop is a powerful construct that simplifies iterative tasks, such as iterating over arrays or collections, executing code a fixed number of times, or performing repetitive operations.

In this example, a for loop is used to iterate over an array of integers and calculate the sum of its elements. The loop initializes the variable i to 0, checks the condition (i is less than the length of the numbers array), and increments i after each iteration. Inside the loop, the current element of the numbers array is added to the sum variable. Once the loop has iterated over all the elements, the calculated sum is printed.
