Hi, I need help with Visual Studio Coding.

In VSCode when you open the project folder you should see:

1. BucketSortMain.java allows you to test your code by choosing different input data.

2. All of the 7 TODOs are found in the IntegerBucketSorter.java file. Each TODO asks you to implement a method. Explanations of what the methods should do are in the comments for each method. We recommend that you implement the TODOs in order from 1 to 7.

3. The Sorter.java is an interface that IntegerBucketSorter implements.

4. The JUnit tests are in the ProjectTests.java file.

After all the ToDos are completed and you run BucketSortMain.java, the sorted output with the sample input data is:

BucketSortMain.java:

package app;

public class BucketSortMain {

public static void main(String[] args) throws Exception{

Sorter s = new IntegerBucketSorter ();

System.out.println("input:");

int[] testArr = {100, 23, 92, 498, 12, 29, 48, 354, 1, 57, 33};

System.out.println(printArr(testArr));

// correct output: 1, 12, 23, 29, 33, 48, 57, 92, 100, 354, 498

int[] resultArr = s.sort(testArr);

System.out.println("output:");

System.out.println(printArr(resultArr));

}

public static String printArr(int[] arr){

StringBuilder sb = new StringBuilder();

for(int i=0;i

sb.append(arr[i]);

if (i

sb.append(", ");

}

return sb.toString();

}

}

IntegerBucketSorter.java: (7 TODOs can be found here)
