Can someone help me please and thank you?

Question about the task

Threads of a string or stringy threads? That's the question

Resolved

In my code,under the OurUncaughtExceptionHandler class, I have literal strings in place for the StringIndexOutOfBounds info. I need help getting this string from the parameters. If anyone has a solution I could look at, I would appreciate it. Thanks.

1. The getPartOfString method must return the substring between the first and the last tab characters.
2. The getPartOfString method should throw an exception if it receives invalid data:
a) StringForFirstThreadTooShortException if the thread's name is FIRST_THREAD_NAME.
b) StringForSecondThreadTooShortException if the thread's name is SECOND_THREAD_NAME.
c) Otherwise, RuntimeException.
3. Implement the logic of the three protected methods in OurUncaughtExceptionHandler using the corresponding method calls according to the following patterns:
a) 1# : StringForFirstThreadTooShortException : java.lang.StringIndexOutOfBoundsException: String index out of range: -1
b) java.lang.StringIndexOutOfBoundsException: String index out of range: -1 : StringForSecondThreadTooShortException : 2#
c) RuntimeException : java.lang.StringIndexOutOfBoundsException: String index out of range: -1 : 3#

Requirements:

The getPartOfString method must return the substring between the first and last tab characters in the string passed as the first argument.
If the getPartOfString method receives invalid data, it should throw a StringForFirstThreadTooShortException if the thread's name (threadName) is Solution.FIRST_THREAD_NAME.
If the getPartOfString method receives invalid data, it should throw a StringForSecondThreadTooShortException if the thread's name (threadName) is Solution.SECOND_THREAD_NAME.
If the getPartOfString method receives invalid data, it should throw a RuntimeException if the thread's name (threadName) is neither Solution.FIRST_THREAD_NAME or Solution.SECOND_THREAD_NAME.
The getFormattedStringForFirstThread method must return a string built using the arguments and formatted in accordance with the pattern specified in the task conditions.
The getFormattedStringForSecondThread method must return a string built using the arguments and formatted in accordance with the pattern specified in the task conditions.
The getFormattedStringForOtherThread method must return a string built using the arguments and formatted in accordance with the pattern specified in the task conditions.

package com.codegym.task.task22.task2201; /* Threads of a string or stringy threads? That's the question */ public class Solution { public static void main(String[] args) { new Solution(); } public static final String FIRST_THREAD_NAME = "1#"; public static final String SECOND_THREAD_NAME = "2#"; private Thread thread1; private Thread thread2; private Thread thread3; public Solution() { initThreads(); } protected void initThreads() { this.thread1 = new Thread(new Task(this, "A\tB\tC\tD\tE\tF\tG\tH\tI"), FIRST_THREAD_NAME); this.thread2 = new Thread(new Task(this, "J\tK\tL\tM\tN\tO\tP\tQ\tR\tS\tT\tU\tV\tW\tX\tY\tZ"), SECOND_THREAD_NAME); this.thread3 = new Thread(new Task(this, "\t\t"), "3#"); Thread.setDefaultUncaughtExceptionHandler(new OurUncaughtExceptionHandler()); this.thread1.start(); this.thread2.start(); this.thread3.start(); } public synchronized String getPartOfString(String string, String threadName) { try { String s= string.substring((string.indexOf("\t")+1),string.lastIndexOf("\t")); return s; } catch (Exception e) { if (threadName.equals(FIRST_THREAD_NAME)) { throw new StringForFirstThreadTooShortException(); } else if (threadName.equals(SECOND_THREAD_NAME)) { throw new StringForSecondThreadTooShortException(); } else throw new RuntimeException(); } } }

This passed testing for me: protected String getFormattedStringForOtherThread(Thread t, Throwable e, String string) { String s = String.format(string, e.getClass().getSimpleName(), e.getMessage(), t.getName() ); return s; } protected String getFormattedStringForSecondThread(Thread t, Throwable e, String string) { String s = String.format(string, e.getMessage(),e.getClass().getSimpleName(), t.getName() ); return s; } protected String getFormattedStringForFirstThread(Thread t, Throwable e, String string) { String s = String.format(string, t.getName(),e.getClass().getSimpleName(), e.getMessage()); return s; }

I run and tested it, console output showing null for getMessage() call. Pass somehow. Lame

Changed to this and overrode toString() to get desired result, but it is not passing. protected String getFormattedStringForOtherThread(Thread t, Throwable e, String string) { String s = String.format(string, e.getClass().getSimpleName(),e.toString(), t.getName()); return s; } protected String getFormattedStringForSecondThread(Thread t, Throwable e, String string) { String s = String.format(string, e.toString(),e.getClass().getSimpleName(), t.getName()); return s; } protected String getFormattedStringForFirstThread(Thread t, Throwable e, String string) { String s = String.format(string, t.getName(),e.getClass().getSimpleName(), e.toString()); return s; } }

solution

i used e.getCause() and even though it doesn't give the correct output when I run it, it verified.
