Question
What needs to go into the blank for the enhanced for loop to output:8 / 2 = 46 / 2 = 34 / 2 = 2int[] numbers = {8, 6, 4 };for(int number : numbers) { System.out.println(number + " / 2 = " + _________);}a.)number / numberb.)number / 2c.)numbers * 2d.)numbers[number] + 2
Solution
The correct answer is b.) number / 2
Here's why:
The enhanced for loop is iterating over each element in the array 'numbers'. Each time it iterates, it assigns the current element to the variable 'number'.
In the print statement, we want to output the current number divided by 2. So, we need to use 'number / 2' to get the desired output.
The other options don't make sense in this context:
a.) 'number / number' would always result in 1 (since any number divided by itself is 1), which is not what we want.
c.) 'numbers * 2' is not valid syntax. 'numbers' is an array, and you can't multiply an array by a number in Java.
d.) 'numbers[number] + 2' would try to use 'number' as an index in the 'numbers' array, which is not what we want. Plus, it adds 2 instead of dividing by 2.
