How do you input numbers into an array?

To input numbers into an array in Java, you will need to follow these steps:

  1. Declare an array variable to store the numbers. You can do this by using the int[] type and giving the array a name:
int[] numbers;
  1. Create an array object with a specific size to store the numbers. You can do this using the new operator and specifying the size of the array:
numbers = new int[10]; // creates an array with 10 elements
  1. Input the numbers into the array. You can do this by using the array access operator ([]) and the assignment operator (=) to assign values to specific elements of the array:
numbers[0] = 1;
numbers[1] = 2;
numbers[2] = 3;
// ... and so on

Alternatively, you can use a loop to input the numbers into the array:

for (int i = 0; i < numbers.length; i++) {
  numbers[i] = ...; // input the number for this index
}

You can also use the shorthand syntax to input numbers into an array, like this:

int[] numbers = {1, 2, 3, 4, 5};

This creates an array with the specified elements and assigns it to the numbers variable in one step.

Keep in mind that arrays in Java are zero-indexed, which means that the first element has an index of 0, the second element has an index of 1, and so on. You will need to make sure that you input the numbers into the correct indices of the array.
