java remove first element from array

removing the first element from an array in java requires a bit of a workaround since arrays in java are of fixed size. when you remove an element from an array, you essentially need to create a new array that does not include the element you want to remove. here’s a detailed tutorial on how to do this, including a code example.

### tutorial: removing the first element from an array in java

#### step 1: understanding arrays in java

in java, an array is a data structure that can hold a fixed number of elements of the same type. once an array is created, its size cannot be changed. therefore, to "remove" an element, we need to create a new array that contains all the elements of the original array except for the one we want to remove.

#### step 2: create a method to remove the first element

we will create a method that takes an array as input and returns a new array with the first element removed.

#### step 3: implement the code

here's a simple implementation:

#### explanation of the code:

1. **method definition**:
- the `removefirstelement` method takes an array of integers (`int[] originalarray`) as an argument.
- it first checks if the array is `null` or empty and returns an empty array if true.

2. **creating a new array**:
- a new array (`newarray`) is created with a size that is one less than the `originalarray`.

3. **copying elements**:
- a `for` loop starts from index `1` of the original array and copies each element to the new array, starting from index `0`.

4. **returning the new array**:
- the new array is returned, which contains all elements of the original array except for the first element.

5. **main method**:
- in the `main` method, an example array is created, and the `removefirstelement` method is called.

this method for removing the first element from an array is straightforward. however, ...
