Question

Create an array in java of integers and fill it with the numbers 2 -4 6 -8 10 ………. -96 98 -100 then display all these numbers. (hint: a%b==0 means a is divisible by b )

Answer 1

To create an array in Java of integers and fill it with a specific pattern of numbers, you can use a for loop and the modulus operator. This allows you to filter numbers and only add those that satisfy certain conditions to the array.

Step-by-step explanation:

To create an array in Java of integers and fill it with the numbers 2, -4, 6, -8, 10, and so on, we can use a for loop. Since the numbers follow a pattern where positive numbers increase by 2 and negative numbers decrease by 4, we can use the modulus operator (%) to determine if a number is divisible by 4. Here's how:

1. Create an empty array of integers.
2. Use a for loop starting from 2 and ending at -100 with a step of -2.
3. In each iteration, use the modulus operator to check if the current number is divisible by 4.
4. If the number is divisible by 4, add it to the array.
5. Finally, display all the numbers in the array using a for-each loop.
