Solution: Java code has been given below along with the output. Comments have been placed in the code to depict the functionality of the different statements.

import java.util.*;
//class definition
//will include the main 
public class TestA{

        public static void main(String args[])
        {

                //variable to store value 25 
                int counter=25;
                //variable to store the odd numbers sum
                int sum =0;
                //variable to store the even numbers multiplication
                int mul =1;

                //Scanner class to read user input
                Scanner reader = new Scanner(System.in);
                System.out.println("Enter 25 numbers");
                for (int i=0;i<25;i++)
                {
                        int x = reader.nextInt();

                        //check even or odd 
                        if (x%2==0)
                        {
                                mul = mul * x;
                        }
                        else 
                        {
                                sum = sum + x;
                        }

                }

                //Print totals
                System.out.println("******* Accumulated Totals ******");
                System.out.println("Even Numbers: "+ mul);
                System.out.println("Odd Numbers: "+ sum);
        }


}

Output:
