- In some circumstances, a class is reliant on itself. That is, one class's object interacts with another class's object. To accomplish this, a method of the class may accept an object of the same class as a parameter.The String class's concat function is an example of this situation. The method is called by one String object and receives another String object as an argument. Here's an illustration:str3 is equal to str1.concat(str2);The method's String object (str1) appends its characters to those of the String supplied as a parameter (str2). As a consequence, a new String object is returned and saved as str3. Create Java code to implement the conditions given.pairRemoval(String,String,String) this is a public static function that takes three strings as arguments and returns a string. You will be given three strings, the first string is a sentence as text that contains at least one occurrence of left pattern and right pattern. The second and third arguments of the function are the left and right patterns respectively. Left pattern and right pattern are single characters strings that you are attempting to remove from the string. Your goal is to remove only the patterns when left pattern has an equal number of corresponding right patterns.Fix the errors in the Customer class and the Program. #include <iostream>#include <fstream>#include <string>using namespace std; class Customer {// Constructorvoid Customer(string name, string address) : cust_name(name), cust_address(address){acct_number = this.getNextAcctNumber();} // Accessor to get the account numberconst int getAcctNumber() { return acct_number; } // Accessor to get the customer namestring getCustName(} const { return cust_name; } // Accessor to get the customer addressstring getCustAddress() const { return cust_address; } // Set a customer name and addressstatic void set(string name, string address); // Set a customer addressvoid setAddress(string cust_address) { cust_address = cust_address; } // Get the next account number for the next customer.static const unsigned long getNextAcctNumber() { ++nextAcctNum; } // input operatorfriend Customer operator>> (istream& ins, Customer cust); // output operatorfriend void operator<<…

Given a text string, construct a new string by reversing its first two characters, then reversing the first three characters of that, and so on, until the last round where you reverse your entire current string.This problem is an exercise in Java string manipulation. For some mysterious reason, the Java String type does not come with a reverse method. The canonical way to reverse a Java string str is to first convert it to mutable StringBuilder, reverse its contents, and convert the result back to an immutable string, that is,str = new StringBuilder(str).reverse().toString(); Here's the tester it must pass: @Test public void testPancakeScramble() throws IOException {// Explicit test casesassertEquals("", P2J3.pancakeScramble(""));assertEquals("alu",…this is my code and the question need to be continued. #include <iostream>using namespace std; class Course{private: string name; string *studentList; int size, capacity=10;public: Course(){ name = "TBD"; size = 0; studentList = new string[capacity]; }Course(string s){ name = s; size = 0; studentList = new string[capacity]; }void setName(string s){ name = s; }getter/accessor for variable name string getName(){ return name; }}; int main(){ Course a, b("Yankee"); cout << a.getName() << endl; a.setName("Mets"); cout << a.getName() << endl; cout << b.getName() << endl; return 0;} this is the Question:: Continue with Team class: a) Copy the previous program to a new file.b) Implement the addMember, removeMember and…
