Here, you do not have the option to skip any element esch it does not work on an index basis. Moreover, you cannot traverse the odd or even elements only.
But, it is recommended to use the Java for-each loop for traversing the elements of array and collection because it makes the code readable. The Java for-each loop traverses the array or collection until the last element. For each element, it stores the element in the variable and executes the body of the for-each loop.

In this tutorial, we will learn about the Java for-each loop and its difference with for loop with the help of examples. In Java, the for-each loop is used to iterate through elements of arrays and collections like ArrayList.
It is also known as the enhanced for loop. Here, we have used the for-each loop to print each element of the numbers array one by one.
In the above program, the execution of the for each loop looks as:. As we can see, we have added each element of the numbers array to the sum variable in each iteration of the loop. Let's see how a for-each loop is different from a regular Java for loop. Here, the output of both programs is the same. However, the for-each loop is easier to write and understand. This is why the for-each loop is preferred over the for loop when working with arrays and collections.
