Final answer:
The correct method to traverse two ArrayLists and print any index that has the same value in both ArrayLists is option c) findCommonIndices(array1, array2).
Step-by-step explanation:
The correct method to traverse two ArrayLists and print any index that has the same value in both ArrayLists is option c) findCommonIndices(array1, array2). This method can be implemented by iterating over each index of the first array and, for each value, checking if it exists in the second array. If a match is found, the index is printed. Here's an example of how the findCommonIndices method can be implemented in Java:
public static void findCommonIndices(ArrayList array1, ArrayList array2) {
for (int i = 0; i < array1.size(); i++) {
int value = array1.get(i);
if (array2.contains(value)) {
System.out.println("Index " + i + " has the same value in both arrays.");
}
}
}
The question asks for the correct method to traverse two array lists and print any index that has the same value in both lists. Without the implementation details of the methods provided (printSharedValues, checkAndPrint, findCommonIndices, compareAndPrint), it's impossible to definitively choose the correct option. However, based on naming conventions in programming, we could assume that a method named 'compareAndPrint' would likely perform a comparison and then print something, possibly the indices with the same value. Generally, a function to accomplish this task would involve iterating over the length of the shorter list, comparing each value at corresponding indices, and then printing the index if the values match.
