Create One Java File For Each Problem And Save Them All

Create One Java File For Each Problem And Save Them All In

You should create one Java file for each problem and save them all in one folder. Compress the folder as a .zip file and submit it here. Please name your .zip file as P4-Last Name-First Name.zip. For example, P4-Smith-John.zip. A Word document containing the algorithms and the screenshots of the running programs for all of the five problems.

Put your algorithm and the screenshots together in a Word document. Problem 1: Write a program that reads the ages of three persons from the user, and decides who is the oldest, and who the youngest person is. Problem 2: Write a program that reads in the name and salary of an employee. Here the salary will denote an hourly wage, such as $9.25. Then ask how many hours the employee worked in the past week. Be sure to accept fractional hours. Compute the pay. Any overtime work (over 40 hours per week) is paid at 150 percent of the regular wage. Print a paycheck for the employee. Problem 3: The original US income tax of 1913 was quite simple. The tax was: 1 percent on the first $50, percent on the amount over $50,000 up to $75, percent on the amount over $75,000 up to $100, percent on the amount over $100,000 up to $250, percent on the amount over $250,000 up to $500, percent on the amount over $500,000. There was no separate schedule for single or married taxpayers. Write a program that computes the income tax according to this schedule. Problem 4: Write a program asks the user to enter a month (1 for January, 2 for February, and so on) and then prints the number of days in the month. For February, print "28 or 29 days". For example: Enter a month: 5 30 days. Do not use a separate if/else branch for each month. Use Boolean operators. Problem 5: A year with 366 days is called a leap year. Leap years are necessary to keep the calendar synchronized with the sun because the earth revolves around the sun once every 365.25 days. Actually, that figure is not entirely precise, and for all dates after 1582 the Gregorian corrections apply. Usually years that are divisible by 4 are leap years, for example 1996. However, years that are divisible by 100 (for example 1900) are not leap years, but years that are divisible by 400 are leap years (for example 2000). Write a program that asks the user for a year and computes whether that year is a leap year. Use a single if statement and Boolean operators.

Paper For Above instruction

This assignment encompasses five distinct programming problems designed to showcase the understanding of fundamental Java programming constructs, including user inputs, conditional statements, mathematical calculations, and control structures. Each problem employs algorithmic logic that can be translated into Java code, and the solutions require the implementation of separate files for modularity. Moreover, the assignment emphasizes documentation through algorithms and visual verification via screenshots, culminating in a comprehensive Word document submission. The following sections elaborate on each problem, their respective algorithmic strategies, and the corresponding Java implementations.

Problem 1: Determining the Oldest and Youngest Among Three Persons

The first problem involves reading the ages of three individuals and identifying the oldest and the youngest among them. The core logic is to compare the three age inputs and output the maximum and minimum values. The algorithm begins by prompting the user to input three ages sequentially. Then, using nested if-else statements or the Math.max and Math.min functions, determine the oldest and youngest. This approach ensures that all comparisons are efficiently handled. The Java implementation creates a Scanner object for input, captures the three ages, and uses built-in functions or conditional logic to find the required persons.

Problem 2: Calculating Employee Pay Based on Hours Worked

The second problem involves salary computation, considering hourly wage and hours worked, including overtime pay. The algorithm prompts the user to input the employee's name, hourly wage, and hours worked (accepting fractional hours). The pay calculation involves multiplying hours by wage, but if hours exceed 40, overtime hours are paid at 150% of the regular rate. The total pay equals the regular pay plus overtime pay. The program then displays a detailed paycheck with employee name, hours worked, gross pay, and possibly taxes deducted. Implementation involves conditionally calculating overtime, and then outputting formatted results.

Problem 3: Computing Historical US Income Tax

The third problem involves applying a progressive tax schedule to compute income tax owed based on income brackets established in 1913. The algorithm first asks the user to input their income. Then, using a series of if-else conditions, the program calculates the tax for each segment. For incomes exceeding certain thresholds, the tax is computed cumulatively by summing each bracket's tax. For example, 1% on the first $50, then 1% on amounts over $50, up to $75, and so on. The implementation must carefully differentiate income ranges and accumulate tax accordingly. This problem illustrates the use of compound conditionals and arithmetic operations.

Problem 4: Number of Days in a Month

The fourth problem requires user input for the month number and outputs the corresponding number of days. February's days are ambiguous (“28 or 29”), so the program must handle that specifically. The algorithm prompts for the month, then uses Boolean operators combined with logical AND, OR to determine the number of days. Avoiding separate if-else branches for each month, the implementation uses logical expressions that group months with the same number of days. The program then displays the number of days or the special message for February.

Problem 5: Leap Year Determination

The fifth problem focuses on identifying whether a given year is a leap year using a single if statement with Boolean operators. The algorithm asks the user for a year, then evaluates the conditions: a year divisible by 4 AND (not divisible by 100 OR divisible by 400). If true, the year is leap; otherwise, it is not. This condition succinctly captures all the rules for leap years according to the Gregorian calendar. The implementation involves a straightforward conditional check and outputs the result.

Implementation Notes and Submission Guidelines

Each program should be written in its own Java file, named appropriately (e.g., Problem1.java, Problem2.java, etc.). Save all files in a folder, compress that folder into a ZIP file named as per instructions, e.g., P4-Smith-John.zip. Create a Word document that includes the algorithms (either pseudocode or flowcharts) and screenshots of the programs running with test cases. The document should be named appropriately, e.g., P4-Smith-John.docx. This comprehensive submission demonstrates both coding proficiency and documentation skills, aligning with best practices for software development and academic assessment.
