Re-write the java program in exercise 8 by developing a method called “StudentsGradesStatistics” and passing the array that contains the students grades to the method that will calculate and print all statistics

import java.util.Scanner;
public class HelloWorld
{
	public static void main(String[] args) {
	    Scanner input=new Scanner(System.in);
	    System.out.println("enter the number of students:");
	    int numberofStudents=input.nextInt();
	    int []grades=new int[numberofStudents];
	    for(int i=0;i<grades.length;i++)
	    {
	        do{
	        System.out.println("enter grade of student "+(i+1));
	        grades[i]=input.nextInt();
	        if(grades[i]>100 || grades[i]<0)
	        System.out.println("invlid grade, it should be between 0 to 100");
	        }
	        while(grades[i]>100 || grades[i]<0);
	        
	    }
	    StudentsGradesStatistics(grades);
	}
	
	public static void StudentsGradesStatistics(int grades[])
	{
	    int numOfPassStudents=0,numOfFailStudents=0,numOfExcelentStudents=0,numOfVeryGoodStudents=0,numOfGoodStudents=0,numOfAcceptanceStudents=0;
	    int highestGrade=-1,lowestGrade=101;
	    for(int i=0;i<grades.length;i++)
	    {
	        if(grades[i]>=60)
	        {
