School works?

[D-X69]

Here's a link to the PDF of my homework:
Fall2011Midterm.pdf

My mid term's over. And I was having trouble getting these following questions to compile and work:
- 2(c) (TransformGrades.java)
- 4(b) (NormalGenerate.java)
- 6(b), (c) (FindMinMax.java)

P.S.: I'm a VIM user.

Anyway, please help me out I need to get these three questions to work and handed in to get some additional marks in my midterm as no one seems to be able to get these questions right in my class.

I need to get these three questions to work

It might help if you could clarify this a bit.

Do you have code that does not compile? If so, what is the code and what are the compiler messages? If you post them maybe someone help explain what they are getting at.

If it's a matter of the questions asking you to write code, what have you written? If it does compile but does not do at runtime what you expect or intend, say what it does do (including any runtime errors) and describe your intentions or expectations.

If it's a question of how you start, common advice is for you to think about the problem and come up with a way in which *you* rather than a computer might perform the task that has been posed. Try and develop a "recipe" that is both precise and comprehensive. Be able to express that recipe lucidly in natural language before you begin to write code.

Many here won't go to the trouble of downloading files and figuring out what a problem *is*. There is an expectation that you will do this.

Okay, I got the first one to work with the help from one of my seniors. And I successfully got it to work. Here's the code:

public class TransformGrade
{
public static void main(String[] args)
{
int c = 0;
int b = 0;
int a = 0;

for(int i = 0 ;i<args.length ;i++)
{
double grade = Double.parseDouble(args[i]);

if (grade<60) c++;

else if (grade>59 && grade<80) b++;

else a++;
}

System.out.print("C : ");

for (int j = c ;j>0 ;j--)
{
System.out.print("*");
}
System.out.println();

System.out.print("B : ");

for (int k = b ;k>0 ;k--)
{
System.out.print("*");
}
System.out.println();

System.out.print("A : ");

for (int l = a ;l>0 ;l--)
{
System.out.print("*");
}
System.out.println();
}
}

However I don't get this part:

for (int j = c ;j>0 ;j--)
{
System.out.print("*");
}
System.out.println();

System.out.print("B : ");

for (int k = b ;k>0 ;k--)
{
System.out.print("*");
}
System.out.println();

System.out.print("A : ");

for (int l = a ;l>0 ;l--)
{
System.out.print("*");
}
System.out.println();
}

Mind doing some explainations? Thanks.

Why don't you ask the person that wrote it?

Why don't you ask the person that wrote it?

Because he cannot explain it in english. He can only explain it in chinese. which is why i asked here. and my chinese is not that good.

Why not go to the tutorials and learn Java, then you can write this yourself *and* understand it. Start here: The Big Index
