Program Plan Intro

String class:

  • The “String” class would provide different methods that examines for a string inside of a string.
  • The term “substring” refers to a string that denotes another string’s part.
  • The “startsWith” method would determine whether calling string of object begins with a particular substring.
    • The method returns “true” if string begins with specified substring, it returns “false” otherwise.
  • The “endsWith” method would determine whether calling string would end with a specified substring.
    • The method returns “true” if string ends with specified substring, it returns “false” otherwise.
  • The “regionMatches” method would determine whether specified regions for two strings match.
    • The first argument for this method could be “true” or “false” that indicates whether a case-insensitive comparison could be performed.
  • The “replace” method substitutes occurrences of one character with another character.

StringBuilder class:

  • The “StringBuilder” class is same as “String” class except that contents of “StringBuilder” objects could be changed.
  • It provides numerous methods that “String” class does not have.
  • The “append” method accepts an argument that might be a primitive data type.
    • It appends a string representation to contents of calling object.
  • The “insert” method accepts two arguments, an integer that specifies position in string of calling object as well as value to be inserted.
  • The “replace” method substitutes occurrences of single character with another character.
  • The “deleteCharAt” method removes character at specified position in sequence
  • The “toString” method converts a “StringBuilder” object in to a regular string.
  • The “replace” method replaces a specified substring with a string.

Q2. Write a program that creates a class named BankAccount and contains: • Private attributes: • • ° ° id int), balance double and annual InterestRate (double). These attributes must never take a negative value. beneficiaries String [] ) to store the names of people who may receive the balance of funds when the account owner passes away. count static int ) to keep a record of the number of created objects. Constructors: 。 A 3-argument constructor that creates an account with given annual InterestRate), balance, and list of beneficiaries passed to the constructor as a series of names, e.g. BankAccount(3300, 6.7, "John", "Lili"). The constructor must increment count by 1, and then stores the new count into id. 。 A no-argument constructor that invokes the above 3-arg constructor and sets both balance and annual Interest Rate to 0, and beneficiaries to a new empty (String array of the size 3. Methods: ° Getter methods for all attributes. ° Setter methods for balance, annual Interest Rate °…
