Question
Select the correct answerWhich of the following is true about the "for" loop in Java?OptionsThe loop variable must be declared and initialized outside the loopThe loop variable is automatically incremented or decremented after each iterationThe loop can have only one iterationThe loop body must contain a condition
Solution
The correct answer is: The loop variable is automatically incremented or decremented after each iteration.
Here's why:
-
The loop variable can be declared and initialized inside the loop. For example: for(int i = 0; i < 10; i++){}.
-
In a "for" loop, the loop variable is automatically incremented or decremented after each iteration. This is specified in the third part of the loop statement (i++ or i-- in the above example).
-
A "for" loop can have any number of iterations, not just one. The number of iterations is determined by the loop condition.
-
The loop body does not necessarily need to contain a condition. The condition is specified in the second part of the loop statement (i < 10 in the above example). The loop body contains the code that is executed in each iteration.
