Array help counting # of grades

[speaknspell]

It's a lot like other programs already posted, but not quite--I promise I searched! The program calcs the sum, the average, the highest and lowest score. I have no problems with that. BUT it supposed to also tell me how many scores were 90 or above, 80 to 90, 70 to 80. That's the problem I'm having. I know the code is ugly, but I don't really know what to do with it. Any help is really appreciated:)

public class Chp8Assign1
{
	public static void main (String [] args)
	{
		int myArray[] =  new int[args.length];
		//for loop to convert String args array to integer myArray
		for(int a=0; a<args.length;a++)
		{
			myArray[a]=Integer.parseInt(args[a]);
		}
		

		int sum = 0;
		int largest = myArray[0];
		int smallest = myArray[0];


		int gradeA = 0;   //variable for grades 90-100
		int gradeB = 0;  //variable for grades 80-90
		int gradeC = 0;  //variable for grades 70-80
		int gradeD = 0;  //variable for grades 60-70
		int gradeF = 0;  //variable for grades below 60
		int aGrade=0;  //to count number of gradeA
		int bGrade=0;  //to count number of gradeB
		int cGrade=0;  //to count number of gradeC
		int dGrade=0;  //to count number of gradeD
		int fGrade=0;  //to count number of gradeF

		for(int i=0;i<myArray.length;i++)  //loops through the array to sum, find largest number, then smallest, then check for number of A's, B's, etc.
		{
			sum=sum+myArray[i];
			if(myArray[i]>largest)
				largest = myArray[i];
			if(myArray[i]<smallest)
				smallest = myArray[i];
				
			if((myArray[i]>=90)&&(myArray[i]<=100)) //checks for grading
				gradeA=aGrade;	
			if((myArray[i]>=80)&&(myArray[i]<90))
				gradeB=bGrade;	
			
			if((myArray[i]>=70)&&(myArray[i]<80))
				gradeC=cGrade;	

			if((myArray[i]==60)&&(myArray[i]<70))
				gradeD=dGrade;	

			if(myArray[i]<60)
				gradeF=fGrade;	
			
		}//end of for
		System.out.println("The sum is " + sum);
		System.out.println("The average is " + sum/myArray.length);
		System.out.println("The largest number is " + largest);
		System.out.println("The smallest number is " + smallest);
		System.out.println("Thenumber of students with scores of 90-100 (A) is " + aGrade++);
		System.out.println("The number of students with scores of 80-90 (B) is " + bGrade++);
		System.out.println("The number of students with scores of 70-80 (C) is " + cGrade++);
		System.out.println("The number of students with scores of 60-70 (D) is " + dGrade++);
		System.out.println("The number of students with scores below 60 (F) is " + fGrade++);
	}//end of main
}//end of program

can you please comment your code to say what each portion is supposed to do? i just see a whole bunch of setting variables to be 0.

you need a counter to keep track of the number of students. What you're doing now is just setting the last student to get that grade as gradeA, gradeB etc. try

if((myArray[i] >= 60) && (myArray[i] <70)){
     gradeD++;
}

and print out gradeD instead of gradeD++

Sorry 'bout that. I edited the original message to reflect the comments.

Thanks -- it worked!! I'm so appreciative. I'm new to this forum and other forums keep track of successful help per person. Is there one of those in this one so I can add a "Yes, very helpful" to yours?
