How to use an array in for loop to calculate minimum?

Question

I am trying to use an array, but I am not sure if that is the right way to do this.

I want the first and second integer input to compare with one another, then if there are more they compare with each other.

So here is the piece of the code.

for(int ii = 1, j = 0; j <= copySel ; ii++, j++) {     
             int x = 0;
             int[x] check;
                // Prompt as follows
                System.out.print("Enter value " + ii + ": ");
                try {
                    c = Get();
                }
                catch (InputMismatchException e) {
                    // Display the following text in the event of an invalid input
                    System.out.println("Invalid input!");
                    ii--; x--;
                } check = c; x++;    

                System.out.print(check + " "+ x);
        }

My actual format is not this bad. I need to try to find the minimum value depending on the number of integer the user has input

static int Get()
    {
        Scanner intFind = new Scanner(System.in);
        int select;
        select = intFind.nextInt();
        return select;
    }

This is Get() ^

cant I use min(x, y) continuously?

int min=a[0];

for(int i=1;i<n;i++)
{
    if(a[i] < min) 
         min = a[i];
}

System.out.println("The min is "+min);

What do you mean by this, does it go in the original for loop?

what is n here I think n is a.length

 System.out.print("Enter value " + ii + ": ");
 int min = Get();
 int c = 0;
 for(int ii = 1, j = 0; j < copySel ; ii++, j++) { 

            // Prompt as follows
            System.out.print("Enter value " + ii + ": ");
            try {
                c = Get();
            }
            catch (InputMismatchException e) {
                // Display the following text in the event of an invalid input
                System.out.println("Invalid input!");
                ii--;
            } min = Math.min(min, c);   

            System.out.print("minimum is:"+ min);
    }

if you want to use ur code you can use the following, u don't have the use clone since Get() doesn't return an array of integer but it returns only 1 int

Very nice. Thanks for the help.

if you have a integer array you could do as below

  Integer [] arr = {5,2,3,4,5,6,7,8};
  List<Integer> list = new ArrayList<Integer>(Arrays.asList(arr));
  Collections.sort(list);
  System.out.println("Minimum "+list.get(0)); ;

 Scanner in = new Scanner(System.in);
 System.out.println("Enter the integers: ");
 String s = in.nextLine();
 string[] str = s.plit(" ");
 int[] a = new a[str.length];
 for(int i =0; i< str.length; i++)
 {
     a[i] = Integer.parseInt(str[i]);
 }
 //Madar's code
 int min=a[0];

for(int i=0;i<a.length;i++)
{
    min = Math.min(a[i], min);
}

System.out.println("The min is "+min);

yes indeed you can instead of the if statement you can write min = Math.min(a[i], min);

I didn't get what your trying to do exactly, but here's some errors you might consider to repair. If check is an array you have to initialize it as such:

int[] check;

Does get() give you back an array of integer, if so you cannot make check = c, you have to copy or clone the content of c into check as such:

check = (int[])c.clone();

I have to get the minimum value

ok then the most straight forward way is to use Mandar's way,
