SiMpLe Program but......I still beginner

[Um Hassan]

Hi everybody,
I have a simple question which Write a method that computes the average, min and max of the values in an array of doubles. The header of the method is as follows:
public static double average(double[] x)
public static double min(double[] x)
public static double max(double[] x) As a beginner java programmer I still have problems in my code.. Could you help me to fetch the true answer.

Code:

class Q5
{
		public static void main(String args[])
	{	
		double [] a= {23.5,64.9,4.2,745.51,81.0};
		double minimum = min(b);
		double maximum = max(c);
		double result  =  average(a);
			
        System.out.println(" Min of array  = " + minimum);
	    System.out.println(" Max of array  = " + maximum);
		System.out.println(" Average of array  = " + result);
	}
	public static double min(double [] x)
	{
		double minimum;
		int i;		
		for(i=0;i<10;i++)
		{
			min(x[i]);
		}
		System.out.println("\n min = " + min(x[i])		
		return minimum;
	}
	//*****************************
	public static double max(double [] x)
	{
			double maximum;
		int i;		
		for(i=0;i<10;i++)
		{
			max(x[i]);
		}
		System.out.println("\n max = " + max(x[i]);		
		return maximum;
	}
	//*****************************
	public static double average(double [] x)
	{
		double avg,sum=0 ;
		int i;		
		for(i=0;i<10;i++)
		{
			sum = sum + x[i];
		}
		System.out.println("\n sum = " + sum);		
		avg = sum / 4 ;	
		return avg;
	}
}

Step 1... You need to make sure that your program can compile first. If you can't compile, you can't run. If you can't run, you can't test. If you can't test, you can't figure out what is wrong. If you can't figure out what is wrong, you can't fix.

So... Does the program compile? What issues are you having when you try to compile it?

And when you post a thread, please tell us what the thread is about in its title. And use the code button to make your code easier to read.

when I compile the program I saw something isn't expected with {......}. Here you are the compile message.

That's a task list of errors in your program. You need to click each one. The IDE will take you to the error, with icons that explain the error. And you need to fix it.

Showing us the task list is pretty useless -- as we don't get any details about the error.


BTW, for a beginner, it is recommended to not use an IDE. An IDE takes care of tons of stuff, that a beginner needs to learn. I highly recommend that you use the standard javac compiler.

Look at lines 6 and 7 of your program:

double minimum = min(b);  
double maximum = max(c);

What are 'b' and 'c'? You haven't declared variables named 'b' and 'c' anywhere, so the compiler doesn't know what you mean there.
