Explanation:

In the code provided, we are creating an array of size 6 to store integer values. The objective is to populate this array by taking input from the user for specific indexes chosen randomly.

To achieve this, we have defined two methods: populateArray and printArray.

The populateArray method takes an array as a parameter and fills it with values provided by the user. Here's how it works:

We create an instance of the Random class to generate random numbers and a Scanner object to read user input.We also create a boolean array called filledIndexes of the same size as the main array. This array will keep track of the indexes that have already been filled.Next, we use a loop to iterate six times (since we want to fill six elements in the array).Inside the loop, we generate a random index using random.nextInt(6). However, we want to make sure that we don't fill the same index twice. So, we check if the index is already filled by checking the corresponding value in the filledIndexes array.If the index is already filled (i.e., filledIndexes[index] is true), we generate a new random index until we find an unfilled one.Once we have a valid, unfilled index, we mark it as filled by setting filledIndexes[index] to true.We then prompt the user to enter a value for the chosen index and read the input using scanner.nextInt(). We store this value in the main array at the corresponding index.This process is repeated six times, ensuring that each index is filled with a unique value.

The printArray method is responsible for printing the contents of the array. It uses a for-each enhanced loop to iterate over each element in the array and prints its value.

**By separating the population and printing logic into separate methods, the code becomes more modular and easier to understand.**
