Please create a Java Program, Using Netbeans JDK, that Asks the operator for 2 numbers, and the user's First and Last Name, and calculates the sum, difference, quotient, and product of the 2 numbers. The program should display to screen: "Hello ";{First Name Last Name} "The Sum is ": {Sum} "The Difference is ": {Difference} "The Product is: ": {Product} "The Quotient is ": {Quotient} Each student should post a Java program should have: (a) Pseudocode and (b) adjacent Java...
Deliverable A zipped NetBeans project with 2 classes app ZipCode Address Classes Suggestion: Use Netbeans to copy your last lab (Lab 03) to a new project called Lab04. Close Lab03. Work on the new Lab04 project then. The Address Class Attributes int number String name String type ZipCode zip String state Constructors one constructor with no input parameters since it doesn't receive any input values, you need to use the default values below: number - 0 name - "N/A" type...
Program#3(17 points): write a java program (SunDigits) as follows The main method prompts the user to enter an integer number. The method then calls Method Sum (defined blew) to add the digits and return their total. The main method then prints the digits total with proper label as shown below Method Sum )is of type integer and takes an integer value. The method recursively adds up the digits and returns their total. Document your code and use proper prompts for...
java /* Q2 (10 pts): Write a method called method that accepts an integer parameter * * * * and returns a sum of the first n terms of the sequence. * In other words, the method should generate the following sequence: 1 + 1/2 + 1/3 + 1/4 + ... 1/n * For example, method2(2) will return 1.5 since 1+1/2 = 1.5 * method2 (15) will return 3.3182289932289937 * You may assume that the parameter n is nonnegative. */...
write a complete Java program that defines a main method and another method called sum. method sum takes 2 integer values, say a and b, and returns the sum of all values between a and b. a must be less than b for the method to return the sum
3. Write a Java method (called sumOfSquares) that reads in a sequence of integer numbers using a Scanner object. As each integer is read, the method displays that integer. The method also accumulates the sum of the squares of the integers and displays the sum when all integers are read. The method reads integers until a negative integer is read. The negative integer should not be display or added to the sum of squares. The method will not return a...
java Part 1 Create a NetBeans project that asks for a file name. The file should contain an unknown quantity of double numeric values with each number on its own line. There should be no empty lines. Open the file and read the numbers. Print the sum, average, and the count of the numbers. Be sure to label the outputs very clearly. Read the file values as Strings and use Double.parseDouble() to convert them. Part 2 Create a NetBeans project...
