CS46A Fall 19

6A

Complete the class, HomeLoanProcessor, an application for a home loan that will be used by a loan officer. Below are some made-up criteria to determine if the loan is granted. These qualifications are for some fictitious place - not the Bay Area!

A loan is granted based on the amount of the loan, annual household income, and the number of years a person has lived at the current address. The loan is granted if

• the loan request is for more than $500,000 and
  • the applicant has lived at their current address for 3 or more years and
  • the applicant's annual income is at least 1/4 of the loan amount
• the loan request is for more than $500,000 and
  • the applicant has lived at their current address for more than 1 year and
  • the applicant's annual income is at least 1/3 of the loan amount
• the loan request is for more than $200,000 but less than or equal to $500,000 and
  • the applicant has lived at their current address for 7 or more years and
  • their annual income is at least 1/5 of the loan amount
• the loan request is for more than $200,000 but less than or equal to $500,000 and
  • the applicant has lived at their current address for 4 or more years and
  • their annual income is at least 1/4 of the loan amount
• the loan request is for $200,000 or less and
  • the applicant's annual salary is 1/3 of the loan amount,
  • it does not matter how long he has lived at the current address
• in all other cases the loan is denied.

Hint: it will simplify your code if you set a boolean variable granted to false and only change it to true if a set of conditions is true.

HomeLoanProcessor has a constructor that takes the loan amount, annual household income, and the number of years a person has lived at the current address

public HomeLoanProcessor(double loanAmount, double annualIncome, int yearsAtCurrentAddress)The parameters must be positive. If only one of them is not positive, set all 3 to 0.

It has these methods

• public double getAnnualIncome() gets the annual household income of the applicant
• public void setAnnualIncome( double income) sets a new annual income. If less than or equal to 0, set loan amount, annual income, and years at current address to 0.
• public void setLoanAmount(double amount) sets a new annual income for this applicant. If less than or equal to 0, set loan amount, annual income, and years at current address to 0.
• public boolean loanGranted() returns true if application meets the stated requirements. Otherwise false
• public double getLoanAmount() provided
• public double getYearsAtCurrentAddress()provided

Provide Javadoc

Use nested ifs for loanGranted. There are other ways to do this, but I want you to use nested ifs. You should have 3 outer if clauses (if / else if / else)

For the draft, provide the constructor, and implement the getAnnualIncome() and setAnnualIncome() methods. Implement setLoanAmount and loanGranted as stubs. Note that a stub with return type boolean returns false. Provide the Javadoc. The Javadoc should document the code that will do in the final not what it does in the draft.

6B

Write an application called LoopsAndMore which gets valid input

Instructions updated Oct 6 to match Codecheck

• Create a Scanner
• Use a loop to get 3 integers from the user. Find the sum and print it. Use this prompt: System.out.print("Enter an integer: "); (updated to "print" Oct 6)
• Use a do loop to get an integer less than 10. Give this prompt: System.out.print("Enter an integer less than 10 ");
• Use a do loop to get a double greater than or equal to 1 and less than 50. Give this prompt: System.out.print("Enter a double between 1 (inclusive) and 50 (exclusive)" );
• Print the double
• Print the product of the two numbers (Product means multiply)
• Print just the integer portion of the product as an integer (Think cast) So if the product is 27.99, you would print 27

Requirement for one loop removed Oct 7

For the draft: Do the first two steps

6B draft:
6B final:

6C

Complete the class StringsAndLoops which has a constructor that takes a String of text. Implement the following methods.

• public String getText() returns the text
• public int getUpperCaseCount() gets the number of the uppercase letters in the text. You can use charAt to get each letter and then use Character's isUpperCase method.
• public int getACount() gets the number of a's in the String, either upper or lower case. Do not change the instance variable
• public String firsts()  gets a string consisting of the first character of every word in the string. If the string is the empty string, return the empty String. 
  Hint: Each word after the first is preceded by a space. You can use the String method indexOf (" ", fromIndex)  to determine where a new word starts.  The next character will be the first letter of a word. indexOf returns -1 if the space is not in the search string so tit can be used as control the loop to tell when to stop.

Provide Javadoc

For the draft, provide the instance variable, constructor, getText() and getUpperCaseCount() methods along with the necessary Javadoc
