What is the error? Can anyone please explain?

Answer 1

import java.io.*;
public class Program
{
public static void main(String args[])throws IOException{BufferedReader r=new BufferedReader(new InputStreamReader(System.in));
int x=1;
int s;
String[] p={"a","b","c","d","e","f","g","h","i","j","k","l","m","n","o","p","q","r","s","t","u","v","w","x","y","z","1","2","3","4","5","6","7","8","9","0","@","#","quot;,"%","&","-","+","*",":",";","!","?","=","^","×","÷"};
int l=Integer.parseInt(r.readLine());
if(l>=8&&l<=20){
for(x=1;x<=l;x++){
s=Math.round(Math.random()*52);
System.out.print(p[s]);
}
}
}
}

Answer 2

The first thing I suggest doing is declaring s as a long instead of an int, then casting s to int inside the System.out.print() call.

long s;
... after a few lines ...
System.out.print(p[(int) s]);

Other than that, I'm not sure what your code is supposed to do, exactly. Please elaborate.
