Storing prompted values in array.

[grbeltran]

Hey everybody,

I am having lots of trouble storing values in an array and I want to be prompt at the beginning of each value. The values I will enter will be two digit values such as 23, or 42, or 35.
Anyways, i am prompted but there is problem with my loop or (char) print statements but i cant get it to work!!!

This is my code:

class prompt2 { 
     public static void main(String[] args) 
          throws java.io.IOException {
 
           int p[] = new int[4];
 
                  for ( int i = 0; i <  4; i++)
     {
      System.out.println("Enter the distance from the center to point p" + i + ":\n");
      p[i] = System.in.read() ;
 
      System.out.println("The numbers in the array for p are:  p0 is: " + p[0] + " p1 is: " + (char) p[1]+ " p2 is: " + 
                (char) p[2]+ " p3 is: " + (char) p[3]);
 
 

Any help is very much appreciated!

Thanks,

Gabe

Use a scanner:
import java.util.Scanner;
class prompt2 {
     public static void main(String[] args)
          throws java.io.IOException {
   Scanner scan = new Scanner(System.in);
           int p[] = new int[4];
           for ( int i = 0; i <  4; i++) {
      System.out.print("Enter the distance from the center to point p" + i + " :");
        p[i] = scan.nextInt() ;
        System.out.println();
   }
   System.out.println("The numbers in the array for p are:  p0 is: " + p[0] + " p1 is: " + p[1]+ " p2 is: " +
   p[2]+ " p3 is: " + p[3]);
  }
 }
 
 

Why were you typecasting to char?

Wow!!!! I never heard of scanners but it worked!!

Thank you!! TY very much!

Now, are u by chance familiar with the Javelin?

Thanks,

What does it do and why did you ask about it?
