Question
Use any loops in Java Language
Write the method named withoutString().
*
* Given two strings, base and remove, return a
* version of the base string where all instances
* of the remove string have been removed (not case
* sensitive). You may assume that the remove
* string is length 1 or more. Remove only non-overlapping
* instances, so with "xxx" removing "xx" leaves "x".
*
* Note: Despite the term "remove" you should actually not
* try to remove the characters from a string. You'll continue
* to use the "building a string" pattern from lecture.
*
* Examples:
* withoutString("Hello there", "llo") returns "He there"
* withoutString("Hello there", "e") returns "Hllo thr"
* withoutString("Hello there", "x") returns "Hello there"
*
* @param base the base String to modify.
* @param remove the substring to remove.
* @return the base String with all copies of remove removed.
*/
// TODO - Write the withoutString method here
/**
* Write the method named sameEnds().
*
* Given a string, return the longest substring
* that appears at both the beginning and end of
* the string without overlapping. For example,
* sameEnds("abXab") should return "ab".
*
* Examples:
* sameEnds("abXYab") returns "ab"
* sameEnds("xx") returns "x"
* sameEnds("xxx") returns "x"
*
* @param str the String to search.
* @return the longest substring that appears at beginning and end.
*/
// TODO - Write the sameEnds method here.
/**
* Write the method named maxBlock().
*
* Given a string, return the length of the
* largest "block" in the string. A block is a run
* of adjacent characters that are the same.
*
* Examples:
* maxBlock("hoopla") returns 2
* maxBlock("abbCCCddBBBxx") returns 3
* maxBlock("") returns 0
*
* @param str the String to examine.
* @return the size of the longest run of adjacent characters.
*/

I checked them they are wrong.arrow_forwardRevorse the vewels def reverse_vowels(text): Given a text string, create and return a new string constructed by finding all its vowels (for simplicity, in this problem vowels are the letters found in the string 'aeiouAEIOU') and reversing their order, while keeping all other characters exactly as they were in their original positions. However, to make the result look prettier, the capitalization of each moved vowel must be the same as that of the vowel that was originally in the target position. For example, reversing the vowels of 'Ilkka' should produce 'Alkki' instead of 'alkkI'. Applying this operation to random English sentences seems to occasionally give them a curious pseudo-Mediterranean vibe.Along with many possible other ways to perform this square dance, one straightforward way to reverse the vowels starts with collecting all vowels of text into a separate list, and initializing the result to an empty string. After that, iterate through all positions of the original text.…arrow_forwardIntegers numberOfParts, required Groups, and invalid Groups are read from input.

Use this method to find the number of prime numbers less than 10000. Below are some clarifications for the Java program (a) The lab is to COUNT the prime numbers less than 10000. Do NOT list the prime numbers. (b) A pair prime is two prime numbers whose difference is 2. For e.g. 3,5; 11,13; 17, 19; etc. We can use IsPrime function to count how many pair primes are there in a range from 2 to 100 for example. Create a function pairPrime, that takes one argument. pairPrime should return the number of pair primes between 2 and the argument passed. Use the pairPrime function to count the pair primes between 2 and 1000. Make use of the IsPrime function to solve this task. (This feature is worth 8 points).
