what is the error here.Can someone help?

The getPartOfString method must return the substring between the first and the second tab characters.
If the input data is invalid, throw a StringTooShortException.
Don't change the StringTooShortException class.

Requirements:

The StringTooShortException class must be a child of the Exception class.
The getPartOfString method must have a String parameter.
If the string passed to the getPartOfString method contains less than 2 tab characters, then a StringTooShortException should be thrown.
The getPartOfString method must return the substring between the first and the second tab characters.

package com.codegym.task.task22.task2203; /* Between tabs */ public class Solution { public static String getPartOfString(String string) throws StringTooShortException { String result=""; if (string == null) { throw new StringTooShortException();} if (!string.contains("\t")) { throw new StringTooShortException();} else{ int v = string.indexOf("\t"); int u = string.indexOf("\t",v+1); if((u!=-1)&&(v!=-1)) { result= string.substring(v,u); return result; } else throw new StringTooShortException(); } } public static class StringTooShortException extends Exception { } public static void main(String[] args) throws StringTooShortException { System.out.println(getPartOfString("\tCodeGym is the best place \tto learn Java\t.")); } }

you can try this code:

if ((u != -1) && (v != -1)) {
    result = string.substring(v+1, u);
    return result;
} else
    throw new StringTooShortException();
