enter code here
import java.io.*;
class Index
{
public static void main(String str[]) throws IOException
{
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
System.out.println("Enter a String");
String a = br.readLine();
System.out.println("\nEnter the Character you want to search for : ");
char ch =(char) br.read();
int chr = a.indexOf(ch);
System.out.println("\nCharcter "+ch+ " is found at location :" +chr);
System.out.println("\n Enter the location and let's see what charcter is present at that
location");
int b = Integer.parseInt(br.readLine());
}
}
As soon as the last statement is coming to execution it is throwing Run-Time Error
Exception in thread "main" java.lang.NumberFormatException: For input string: " "
at java.base/java.lang.NumberFormatException.forInputString(NumberFormatException.java:67)

Where I am going wrong?
