Chapter 9, Problem 4FTE
Explanation of Solution
Given statements:
//Tokenize a string that is delimited
//with semicolons. The string has 3 tokens
String str = "one;two;three"; //Line 1
String tokens = str.split(";"); //Line 2
System.out.println(tokens); //Line 3
Error in the given statement:
Tokenizing string:
- It is a process of breaking down the string into the components called tokens.
- The string can be split using the split method which breaks the string using the delimiter for breaking it.
- The split method is used for the tokenizing the string.
Error #1:
The “tokens” variable must reference the array of tokens that is returned by the method “split ()” in “Line 2”. So the statement must be rewritten as:
String[] tokens = str...

- In this assignment, you will implement a multi-threaded program (using C/C++) that will check for Prime Numbers and Palindrome Numbers in a range of numbers. Palindrome numbers are numbers that their decimal representation can be read from left to right and from right to left (e.g. 12321, 5995, 1234321). The program will create T worker threads to check for prime and palindrome numbers in the given range (T will be passed to the program with the Linux command line). Each of the threads works on a part of the numbers within the range. Your program should have some global shared variables: • numOfPrimes: which will track the total number of prime numbers found by all threads. numOfPalindroms: which will track the total number of palindrome numbers found by all threads. numOfPalindromic Primes: which will count the numbers that are BOTH prime and palindrome found by all threads. TotalNums: which will count all the processed numbers in the range. In addition, you need to have arrays…arrow_forwardHow do you distinguish between hardware and a software problem?
