Method “evenBeforeOdd()” to return the sorted array with even numbers followed by the odd numbers:

//Import required packages

import java.util.Arrays;

//Definition of class Test

public class Test {

    //Definition of main class

    public static void main(String[] args)

    {

        //Create an string array

        int[] list={5,4,2,11,9,10,4,7,3};

        //Call the method evenBeforeOdd()

        evenBeforeOdd(list);

        //Print the array

        System.out.println(Arrays.toString(list));

    }

    //Definition of method vowelCount 

    public static void evenBeforeOdd(int[] a)

    {

        //Declare the required variables

        int i = 0;

        int j = a.length - 1;

        //Check whether the i is less than j

        while (i < j)

        {

//Traversing the while loop till i refers to the even numbers

        while (i < a...
