    I have an assignment I am a bit stuck on. The prompt is: (Find the smallest element) Write a method that finds the smallest element in an array of double values using the following header:
    public static double min(double[] array)
    Write a test program that prompts the user to enter ten numbers, invokes this
    method to return the minimum value, and displays the minimum value.

    Here is what I have so far:

    
  import java.util.Scanner;  public class Exercise6_9 {  	 	public static void main(String[] args) { 		 		Scanner input = new Scanner(System.in); 		System.out.println("Enter 10 numbers."); 		 		double[] numbers = new double[10]; 		 		 		for (int i = 0; i < numbers.length; i++ ){ 			numbers[i] = input.nextDouble(); 			 			  		} 	}  		 			public static double min(double[] numbers){ 				  double min = numbers[10]; 				  for(int i=1;i<numbers.length;i++){ 				    if(numbers[i] < min){ 					  min = numbers[i]; 					   					  System.out.println(min);  				    } 				  } 				  return min;  				} } 			

    I cannot figure out how to print the minimum value. I have tried countless different solutions. I am a complete noob at Java and my question is, am I at least close to the solution? and if so how do I print the minimum value? I get the error that "double[] cannot be defined in exercise 6_9."

    Any help would be much appreciated.

    Yes, you're on the right track. The only thing that's missing is for you to call your min method from the main method and print the result.

    You also probably shouldn't print the current minimum every time that you pick a new minimum, but I assume that's just there for debugging purposes.

    Can you post the exact and complete error message including line numbers and whatnot? I don't get any error message when compiling and running your code.

    A couple points:
    try to watch for indentation.
    (your main is nice and readable, but your min is too indented.)

    next: try to keep your main as small as possible. Only a couple lines.
    Everything else could be done in another method.

    Make only your main (and some variables when necessary) static.

    In order to call those non-static methods in your main you create an new object. (classname name = new classname() )
    Than you can call your methods via the object name.

    Nextup:
    Your program is not entirely correct.
    Any array-index (whether it's double, int, String, ...) always start at 0.
    So item 1 is a index 0.
