for-each loop + java

What is the name of the loop that is used to iterate over the names array in the Java code snippet in the image?

• for loop
• while loop
• do-while loop
• for-each loop

Answer explanation

The answer is for-each loop because the for-each loop is used to iterate over the elements of an array or collection. In the image, the names array is an array of strings, and the for-each loop is used to iterate over each string in the array. The for-each loop is also the only loop that is used in the image.

What is the variable that is used to store the current element in the for-each loop in the image?

• i
• name
• array
• loop

Answer explanation

The answer is name because the for-each loop in the image uses the variable name to store the current element in the array. This can be seen in the line of code for (String name : names). The name variable is then used in the body of the loop to perform some operation on the current element.

What is the name of the collection that is used in the for-each loop in the image?

• names
• numbers
• stream
• array

Answer explanation

The answer is stream because the for-each loop in the image is using the Stream class to iterate over the elements of the collection. This can be seen in the line of code Stream.of(1, 2, 3, 4, 5). The Stream class provides a variety of methods for iterating over collections, including the forEach() method that is used in the for-each loop.

What is the name of the variable that is used to store the current element in the for-each loop in the image?

• i
• arr
• element
• index

Answer explanation

The answer is element because the for-each loop in the image uses the variable element to store the current element in the array. This can be seen in the line of code for (int element : arr). The element variable is then used in the body of the loop to perform some operation on the current element.

What is the variable name that is used to store the current element in the for-each loop in the image?

• i
• array
• num
• element

Answer explanation

The answer is num because the for-each loop in the image uses the variable num to store the current element in the array. This can be seen in the line of code for (int num : array). The num variable is then used in the body of the loop to perform some operation on the current element.

What is the name of the variable that is used to store the current element in the for-each loop in the image?

• name
• listofNames
• i
• array

Answer explanation

The answer is name because the for-each loop in the image uses the variable name to store the current element in the list. This can be seen in the line of code for (String name : listofNames). The name variable is then used in the body of the loop to perform some operation on the current element.

What is the type of the variable that is used to store the current element in the for-each loop in the image?

• String
• ArrayList
• int
• Integer

Answer explanation

The answer is String because the for-each loop in the image uses the variable item to store the current element in the ArrayList, which is a collection of strings. This can be seen in the line of code for (String item : itemsArrayList). The item variable is then used in the body of the loop to perform some operation on the current element.

What is the type of the variable that is used to store the current element in the for-each loop in the image?

• int
• String
• char
• double

Answer explanation

The answer is int because the for-each loop in the image uses the variable firstArray to store the current element in the int[] array, which is a collection of integers. This can be seen in the line of code for (int firstArray : value). The firstArray variable is then used in the body of the loop to perform some operation on the current element.

What is the name of the array that is used in the for-each loop in the image?

• names
• nums
• array
• list

Answer explanation

The answer is names because the for-each loop in the image uses the variable names to iterate over the elements of the array. This can be seen in the line of code for (String name : names). The names variable is then used in the body of the loop to perform some operation on the current element.

What is the name of the variable that is used to store the current element in the for-each loop in the image?

• name
• array
• index
• counter

Answer explanation

The answer is name because the for-each loop in the image uses the variable name to store the current element in the array. This can be seen in the line of code for (String name : names). The name variable is then used in the body of the loop to perform some operation on the current element.
