In Java all the methods should include all the given options except “a call to another method”.
Hence, the correct answer is option “A”.
Explanation of Solution
Method:
A collection of statements which are formed together to perform an operation is called as method.
Declaration of a method:
Method declaration gives the description of what the method should perform; Method declaration holds the modifier, return type, name of the method, the list of parameters and the body of the method.
Syntax for defining a method:
modifier return_type methodName(list of parameters)
{
//body
}
Example:
public int findArea(int x, int y)
{
//body
}
The above statement shows the declaration of the method; here,
- public – modifiers
- int – return type
- findArea – name of the method
- x, y – formal parameters
- int x, int y – list of parameters
- Body is the part of the method that contains the statements and the operations to be performed.
Braces:
- Braces usually enclose the number of statements.
- In a function, the numbers of statements are enclosed within the braces.
- The opening of the function contains the open braces “{”.
- The ending of the function contains the close braces “}”.

- I am struggling on this one. This is the question - Write an application that computes and displays the day on which you become(or became) 10,000 days old. For example, if you we're born on January 1st, 2000, the output would be I will be 10000 days old on 2027-05-19.

- Hello, i need help with this question There are 12 inches in a foot and 3 feet in a yard. Create a class named InchConversion. Its main() method accepts a value in inches from a user at the keyboard, and in turn passes the entered value to two methods. One converts the value from inches to feet, and the other converts the same value from inches to yards. Each method displays the results with appropriate explanation. Save the application as InchConversion.java.arrow_forwardCreate a new Java program called MyInfo.

- For the Java code below, you will demonstrate the ability to use and call multiple methods in your program. Using the code below, create the following methods: 1. A method that converts the temperature from Fahrenheit to Celsius. The method should be passed a parameter - Fahrenheit and should return a result - Celsius. 2. A method to output the results of your temperature conversion. The method should be passed 2 parameters - temperature in Fahrenheit and the temperature in Celsius. Finally, place an edit in your code to ensure that the user only enters a numeric value. Your output should appear as follows: Enter the Fahrenheit temperature you want to convert: 212 This converts to 100 Celsius Do you want to convert another temperature – Y or N? Y Enter the Fahrenheit temperature you want to convert: 100 This converts to 37.8 Celsius Do you want to convert another temperature – Y or N?

Classes you need to design include the following: • Person — A Person contains the following fields, all of type String: firstName, lastName, address, zip, phone. The class also includes a method named setData that sets each data field by prompting the user for each value and a display method that displays all of a Person’s information on a single line at the command line on the screen. For example: Joe Smith 111-N-Student-Lane 88888 888-888-8888 • CollegeEmployee — CollegeEmployee descends from Person. A CollegeEmployee also includes a Social Security number (ssn of type String), an annual salary (annualSalary of type double), and a department name (dept of type String), as well as methods that override the setData and display methods to accept and display all CollegeEmployee data in addition to the Person data. The display method should display…arrow_forwardWrite a method named raiseSalary that accepts two integers as an argument and returns its sum multiplied by 15%.

- Create a class named Percentages whose main() method holds two double variables, and prompt the user for values. Pass both variables to a method named computePercent() that displays the two values and the value of the first number as a percentage of the second one. For example, if the numbers are 2.0 and 5.0, the method should display a statement similar to: 2.0 is 40 percent of 5.0. Then call the method a second time, passing the values in reverse order. An example of the program is shown below: Enter a double >> 3.7 Enter another double >> 12.3 3.7 is 30.081300813008127 percent of 12.3 12.3 is 332.43243243243245 percent of 3.7 Task 01: Create the Percentages class. Task 02: The computePercent() method displays the percent of the first argument of the second argument. Task 03: The Percentages program accepts 2 double values from the console and displays the percent of first value of the second value and vice versa.arrow_forwardCreate an application in Java that calculates the amount of interest for a loan amount. ConsoleWelcome to the Interest CalculatorEnter loan amount: 520000Enter interest rate: .05375Loan amount: $520,000.00Interest rate: 5.375%Interest: $27,950.00Continue? (y/n): yEnter loan amount: 4944.5Enter interest rate: .01Loan amount: $4,944.50Interest rate: 1%Interest: $49.45Continue? (y/n): nSpecificationsThis application should use the BigDecimal class to make sure that all calculations are accurate. It should round the interest that's calculated to two decimal places, rounding up if the third decimal place is five or greater. The application should format currencies to allow for up to 2 decimal places and percentages to allow for up to 3 decimal places. Assume that the user will enter valid double values for the loan amount and interest rate. The application should continue only if the user enters 'y' or 'Y' to the question to continue.arrow_forwardPlease answer the JAVA question below.
