The for loop is a fundamental construct in the Java programming language. It allows you to repeat a block of code multiple times, iterating over a sequence of values. In Java, the for loop consists of three parts: initialization, condition, and update. This article will focus on the execution of the loop condition and its role in determining whether the loop should continue or terminate.
When a for loop is executed, the loop condition is evaluated before each iteration. If the condition evaluates to true, the loop body is executed; otherwise, the loop is terminated. The loop condition can be any expression that results in a boolean value — true or false. This allows for flexibility in controlling the flow of the loop.
It is important to note that the loop condition is evaluated at the beginning of each iteration. This means that if the condition is initially false, the loop body will not be executed at all. Additionally, if the condition becomes false during the execution of the loop body, the loop will terminate immediately, and the program will continue with the next statement after the loop.
The loop condition is typically defined using relational and logical operators, such as ==, !=, <, >, <=, >=, &&, and
