You're using an "enhanced for loop":

for (int number : nums) {
    System.out.println(nums[number]);
}

This is equivalent to:

for (int i = 0; i < nums.length; i++) {
    int number = nums[i];
    System.out.println(nums[number]);
}

So you using nums[number] means you're accessing the array with an index whose value is an element of the array. If the element at nums[0] is 1 then the first element printed out will be the element at nums[1].


Note you probably meant to use:

for (int number : nums) {
    System.out.println(number);
}

Whether or not this solves your problem completely is difficult to say and would depend on what you're actually trying to do.

Clear way to skip the first element in an index based for loop , Not something that simply says THAT we're skipping the first element. so there are no sideffects array_shift($array); foreach($array => $element) { // do stuff } }. I suppose you could skip the first iteration of an Iterator, but there would be no guarantee that you always skip the same first element. – Sean Adkinson Apr 19 '11 at 1:48 There was also one more bracket :) – Bakudan Sep 18 '12 at 9:00


Please try the following code:

 for (int currentNumber : nums) {
        System.out.println(currentNumber);
    }

I've tried renaming the variable used in the iteration so it is easier to understand how to print it / manipulate it.

For this reason when you use nums[number] at the 1st iteration you are printing nums[1]

How to skip the first element of a for-loop in Python, Skipping the first element of a for-loop iterates over all elements of an iterable except the first. For example, iterating over the list [0, 1, 2, 3] and skipping the first​  Like comparing elements with their predecessors (which I thought to be the most-frequent use case to start at 1 - and I fail to see any useful constant name here). If the first element has some ultra-special meaning, the design might be broken, and there should be better fixes than naming that index.


You're accessing the array again inside the for clause, when that is what the for is already doing.

With that in mind, your code should look like this:

for (int number : nums) {
    System.out.println(number);
}

What you were doing is access the array at the position indicated by the value from the array being read.

Hope this helps!

Ignoring the First Element When Looping an Array in CoffeeScript, serves the same purpose as a foreach loop in other languages, such as C#. However, you can't skip the first element without doing a check. Skip the first element. using System; using System.Linq; using System.Collections; using System.Collections.Generic; public class MainClass { public static void Main


You can get value directly in number varible. You won't get index in number variable. This is exact solution.

for (int number : nums) {
    System.out.println(number);
}

How to Use forEach() to Iterate an Array in JavaScript, The first argument of forEach() is the callback function called for every item in the array. The second Let's access the index of each item in the colors array: forEach() skips the empty slots of the array (named sparse array). Some times you need to skip first element from the array of arguments $x. $x = 1,2,3,4  Variant #1 Variant #2


JavaScript continue: Skips the Current Iteration of a Loop, How the script works. First, the counter variable is set to zero. Second, the for loop steps iterate over a string and counts the  When the entry containing the value two is reached, the first entry of the whole array is shifted off—resulting in all remaining entries moving up one position. Because element four is now at an earlier position in the array, three will be skipped. forEach() does not make a copy of the array before iterating.


Determine the first and last iteration in a foreach loop in PHP , Method 1: It is the naive method inside foreach loop to find iteration. Use a counter variable and check when the counter value is zero then it is the first iteration  In a for loop, you can easily skip the current item by using the continue keyword or use break to stop the loop altogether. But that is not the case with the forEach() method. Since it executes a callback function for each element, there is no way to stop or break it other than throwing an exception.


Change C# foreach loop with LINQ methods · Kodify, Skip first item of a foreach loop​​ But foreach has no such thing. So how to skip the first element? The Skip() LINQ method excludes an arbitrary number of elements from the start of a collection. When we call that method before the loop starts, we can exclude the first element. You must note though that using array_shift() will reset all numerical array keys to start counting from zero while literal keys will remain unchanged.; Using both array_shift() and array_pop() resets the array pointer of the input array after use, but in our case that doesn't matter since we're using a copy of the original array, that too with only a single element.
