Question

Code a java statement that is the for each equivalent of the following for loop that loops through an array of doubles:

for (int i = 0; i < dblArray.length; i++)

Answer 1

The for-each equivalent of the provided for loop for an array of doubles in Java is 'for (double element : dblArray) { /* code */ }'. This enhanced for loop improves readability and is used when you do not need the array's index.

Step-by-step explanation:

To create a for-each loop in Java that is equivalent to the provided for loop for traversing an array of doubles, you'd write the following statement:

for (double element : dblArray) {
// Your code here
}

In this for-each loop, element represents the current double value in the dblArray during each iteration. This way of looping is also referred to as an enhanced for loop and it is generally used for its readability and ease of implementation when you do not need the index of the array.

The equivalent code using a for-each loop in Java to loop through an array of doubles is shown below:

for (double num : dblArray) {

// Code to be executed for each element of the array

}

In this code, the variable 'num' will take on the value of each element in the 'dblArray' array in each iteration of the loop. You can perform any operations or computations on 'num' within the loop.
