Concept explainers
(Integer Value of a Character) Here’s another peek ahead. In this chapter, you learned about integers and the type int. Java can also represent uppercase letters, lowercase letters and a considerable variety of special symbols. Every character has a corresponding integer representation. The set of characters a computer uses together with the corresponding integer representations for those characters is called that computer’s character set. You can indicate a character value in a program simply by enclosing that character in single quotes, as in ‘A’.
You can determine a character’s integer equivalent by preceding that character with (int), as in
(int) ‘A’
An operator of this form is called a cast operator. (You’ll learn about cast operators in Chapter 4.) The following statement outputs a character and its integer equivalent:
System.out.printf("The character %c has the value %d%n", ‘A’, ((int) ‘A’));
When the preceding statement executes, it displays the character A and the value 65 (from the Unicode® character set) as part of the string. The format specifier %c is a placeholder for a character (in this case, the character ‘A’).
Using statements similar to the one shown earlier in this exercise, write an application that displays the integer equivalents of some uppercase letters, lowercase letters, digits and special symbols. Display the integer equivalents of the following: A B C a b c 0 1 2 $ * + / and the blank character.

The highest and lowest scores are thrown out and the remaining scores are added together. The sum is then multiplied by the degree of difficulty for that dive. The degree of difficulty ranges from 1.2 to 3.8 points. The total is then multiplied by 0.6 to determine the diver’s score. Write a computer program that will ultimately determine the diver’s score. This program must include the following methods: A method name inputValidScore that inputs one valid score for one judge for one diver. This method will return the valid score. A method named inputAllScores that creates an array to store the scores for all judges for the diver. This method will fill the array with a valid score from each judge. This method does not take input arguments, but it does return the array of scores. A method named inputValidDegreeOfDifficulty that inputs a…arrow_forward
- please solve the question new solution, don't copy other solutions in questions bank c++ In this task, you are required to write a code that converts an Octal number into its equivalent Decimal value or vice versa. The user first selects the conversion choice by inserting 1 or 2. Choice 1 is followed by inserting an Octal integer and getting its Decimal equivalent value as an output. Choice 2 requires inserting a Decimal integer and prints out its Octal equivalent. The Octal numeral system, is the base-8 number system, and uses the digits 0 to 7, that is to say 10 octal represents 8 Decimal and 100 octal represents 64 Decimal. Convertion from an Octal integer into Decimal In the Decimal system, each number is the digit multiplied by 10 to the power of its location (starting from 0). For example: 74 decimal = 7 x 10^1 + 4 x 10^0 1252 decimal = 1 x 10^3 + 2 x 10^2 + 5 x 10^1 + 2 x 10^0 each number is the digit multiplied by 8 to the power of its location (starting from 0).…arrow_forwardsolve in c++arrow_forwardPlease help with the following in JAVAarrow_forward

Solving a Person's Loneliness by CodeChum Admin It's been 1,245 years and our sole Person is getting lonelier each day. This Person definitely needs a partner! Thus, we need to update our Person's design to have a gender as well and there shall be male and female! Instructions: In the code editor, you are provided with the definition of a struct Person. This struct needs an integer value for its age. Furthermore, you are provided with a displayPerson() function which accepts a struct Person as its parameter. Your task is to first update the struct Person so that it can have a gender as well. For this program, we shall represent a gender with a single character: 'M' for male and 'F' for female. Then, create a Person, take in an integer user input and a character user input, and then set them as the Person's age and gender respectively. Finally, call the displayPerson() function and pass that Person you created. Input 1. The age of the Person 2.…arrow_forward
