Remove an Element at Specific Index from an Array in Java - GeeksforGeeks
July 11, 2025 - Explanation: This example includes finding the element at the specified index and then removing that element. The rest of the elements are copied into a new array. This would lead to an array of size one less than the original array. We can use Java 8 streams to remove element at specific index from an array, when modifying small or mid-sized arrays.

May 2, 2025 - To remove an element from an array by index in Java, you need to create a new array with the desired size, copy elements before the index to be removed to the new array, and then copy elements after the index to be removed to the new array, starting from the position of the element to be removed.

Having trouble with java arrays, removing an element then returning a new size of an array
I’m on my phone so I’ll just explain what im thinking in pseudo code, but why don’t you just do something like: Create a new array of size n-1 where n is the size of the original array. Iterate over the old array in a for loop, adding each element to the new array. If the element at the ith position equals the element to remove, continue to the next iteration. Would that work? EDIT: I'm at my PC now so here's the code. I ended up doing it a little differently than I mentioned above. Note that it doesn't account for if the element appears multiple times in the array or when the element does not exist. public static void main(String []args) { int[] myArray = { 5,6,9,4 }; int[] newArray = removeElem(myArray, 9); for (int i = 0; i < newArray.length; i++) System.out.print(newArray[i] + " "); } public static int[] removeElem(int[] array, int value) { int index = -1; // First confirm the element to remove exists in the array for (int i = 0; i < array.length; i++) { // If it does, store its index if (array[i] == value) index = i; } // If element exists if (index != -1) { int[] newArray = new int[array.length - 1]; for (int i = 0; i < array.length; i ++) { if (i < index) newArray[i] = array[i]; else if (i > index) newArray[i - 1] = array[i]; } return newArray; } // Do some error handling for if the element does not exist else return array; } Output is: 5 6 4 More on reddit.com

Remove Element from an Array in Java
December 16, 2021 - The final argument is the number of elements to copy from the source array. The arraycopy is generally used to copy contents from some source array into some destination array. Though, we can also copy an array, or a part of it, into itself. This allows us to shift a part of it to the left like last time: int[] array = {10, 20, 30, 40, 50, 60, 70, 80, 90, 100}; int index = 3; To remove the element, we only need to write this one line of code:

Your question isn't very clear. From your own answer, I can tell better what you are trying to do:
public static String[] removeElements(String[] input, String deleteMe) {
List result = new LinkedList();
for(String item : input)
if(!deleteMe.equals(item))
result.add(item);
return result.toArray(input);
}
NB: This is untested. Error checking is left as an exercise to the reader (I'd throw IllegalArgumentException if either input or deleteMe is null; an empty list on null list input doesn't make sense. Removing null Strings from the array might make sense, but I'll leave that as an exercise too; currently, it will throw an NPE when it tries to call equals on deleteMe if deleteMe is null.)
Choices I made here:
I used a LinkedList. Iteration should be just as fast, and you avoid any resizes, or allocating too big of a list if you end up deleting lots of elements. You could use an ArrayList, and set the initial size to the length of input. It likely wouldn't make much of a difference.

LinkedLists are great when: - adding to the start or the end - removing from the start or the end - adding, removing or setting using a ListIterator All direct element accesses will require the list to be traversed until that element is found, and that's what makes it slow if you use any indexed method.

Remove/Delete An Element From An Array In Java
April 1, 2025 - To remove an element from an array, we first convert the array to an ArrayList and then use the ‘remove’ method of ArrayList to remove the element at a particular index. Once removed, we convert the ArrayList back to the array. The following implementation shows removing the element from an array using ArrayList. import java.util.*; import java.util.stream.*; class Main { public static int[] remove_Element(int[] myArray, int index) { if (myArray == null || index < 0 || index >= myArray.length) { System.out.println("non-existing index"); return myArray; } //array to arrayList List<

Assuming you do not want your array to contain null values, then you would have to make a method that does it. Something like this should suffice:
public char[] remove(int index, char[] arr) {
char[] newArr = new char[arr.length - 1];
if(index < 0 || index > arr.length) {
return arr;
}
int j = 0;
for(int i = 0; i < arr.length; i++) {
if(i == index) {
i++;
}
newArr[j++] = arr[i];
}
return newArr;
}
Then just replace the old array with the result of remove().

If you don't want to use ArrayList, arraycopy is an alternative:
System.arraycopy(words, 0, result, 0, i);
System.arraycopy(words, i+1, result, i, result.length-i);
where i is your index to delete.
Hope I can help.
EDIT: Of course you should initially define the correct array lengths:
char[] result = new char[words.length-1];

r/learnprogramming on Reddit: Having trouble with java arrays, removing an element then returning a new size of an array
July 13, 2018 -
So guys i'm having trouble finding a solution for this question. I'm kinda frustrated that i didn't solve this kind of problem during my exam for employment.
Problem: The task is to provide an implementation for the given function. int[] removeElem(int[] array, value), the objective is to find if the array contains the given 'value' inside it. if found then remove the element from the array then return an array with a new size, else return original array.
So far this is what i got:
public static void main(String[] args) {
int[] myArray = {5,6,9,4};
int[] newArray = removeElem(myArray,9);
for(int i=0;i<newArray.length;i++){
System.out.print(newArray[i] + " ");
}
}
public static int[] removeElem(int[] array, int value){
int[] tempArray = array;
int newArrayLength = 0;
int[] newArray;
for(int index=0;index < tempArray.length; index++){
if(tempArray[index] == value){
tempArray[index] = -1;
newArrayLength++;
}
}
newArray = new int[tempArray.length - newArrayLength];
for(int index=0;index < newArray.length; index++){
if(tempArray[index] != -1){
newArray[index] = tempArray[index];
}
}
return newArray;
}Unfortunately i can't get it right :/
Edit: Thank you! everyone for suggesting different solutions to this problem, I feel like I need to work more on my solutions and such :|.

newArray[index] = tempArray[index]; This is your problem. As you skip elements that are to be removed, the insertion index in newArray must no longer match the read index in tempArray, but you're using the same index for both. You need to use two indices, and only increment the newArray index when you insert an element, while incrementing the tempArray index every time. Also the whole thing would be better if you just used Lists or Streams, but maybe your interviewer didn't want that. It's really best to try to avoid using raw arrays in Java.

you can't delete the index or element of array because it's already sized in the memory so you can't use delete but you can put two values { null or 0 } or another values you want to show that you already get of this.

Arrays cannot be resized. Use a List<Integer> (such as an ArrayList<Integer>) if you want a collection with resizability.
Otherwise, you'll have to implement this yourself by making a copy of the array that is one element smaller than the original array. Then copy all of the values except the one at the specified index from the old array to the new array.
