array crud operation using java tutorial

certainly! in java, crud operations (create, read, update, delete) can be performed on arrays. although java arrays have a fixed size, you can still demonstrate these operations by manipulating the contents of the array. below is a tutorial that explains these operations with code examples.

tutorial: crud operations using arrays in java

1. create

creating an array in java can be done by declaring the array and initializing it with values. here's how you can create an array:

2. read

reading an element from an array can be done by accessing the index of the array. here’s how to read elements:

3. update

to update an element, simply assign a new value to the desired index of the array:

4. delete

deleting an element from an array requires shifting elements since arrays in java have a fixed size. instead, you can set the element to a specific value (like `0` or `null`), or create a new array without the unwanted element.

complete example

here’s how you can put all of the above methods together in a complete example:

explanation

1. **create**: initializes an array and fills it with values.
2. **read**: accesses an element at a specified index.
3. **update**: changes the value of an element at a specified index.
4. **delete**: creates a new array excluding the specified element.

conclusion

this tutorial demonstrated basic crud operations on arrays in java. remember that arrays have a fixed size and that deleting elements involves creating a new array. for more dynamic data structures, consider using `arraylist` or other collections provided by java.
