java user input array

sure! in java, user input can be taken using various methods, but one of the most common ways is by using the `scanner` class. in this tutorial, we will focus on how to take user input to fill an array.

### tutorial: taking user input to fill an array in java

#### step 1: setting up your environment
make sure you have java installed on your machine. you can write and run your java code using any ide (like intellij idea, eclipse, or netbeans) or a simple text editor and command line.

#### step 2: importing the scanner class

#### step 3: creating the array
we will create an array to store the user input. the size of the array can be determined based on user input or predefined.

#### step 4: taking user input
we will use the `scanner` class to read input from the user and fill the array.

#### step 5: displaying the array
after filling the array, we will print its contents to confirm that the input was successful.

### code example
here’s a complete java program that demonstrates the above steps:

### explanation of the code:

1. **importing the scanner class**:

2. **creating the scanner object**:

3. **taking array size input**:

4. **creating the array**:
- `int[] numbers = new int[n];` creates an integer array of size `n`.

5. **filling the array**:
- a `for` loop is used to iterate and fill the array with user input.

6. **closing the scanner**:

7. **displaying the array**:
- another loop is used to print out the elements of the array after they have been entered.
