Lab 2: Small Programs

Overview

The purpose of this assignment is to gain experience writing in Java.

Details

Your instructor may ask you to implement code for this laboratory assignment in IntelliJ or CodingBat. Be sure to follow your instructor's instructions.

Negate

Given a number, return its negative.

• CodingBat

How Many Pennies

Given a number representing dollars and cents, e.g. 2.18, return the number of pennies corresponding to that amount.

• CodingBat

Last Half

Given a non-empty string with an even number of characters, return the last half. E.g., Given "this" return "is".

• CodingBat

Make Initialization

Make a program that writes a line of Java code. Given the name of the variable and its value, return an initialization of an int with that name and value. E.g., given the name "x" and the value "5", return "int x = 5;"

• CodingBat

Fraction

Given a fraction expressed as a numerator and denominator, return the fraction as a floating point number.

• CodingBat

Sample Console Interaction

If you are required to use IntelliJ for your implementation, your program interaction should look like this:

1. Negate
Enter an integer value: -3
Result: 3


2. How Many Pennies
Enter a dollar amount: 2.18
Result: 218


3. Last Half
Enter a word: this
Result: is


4. Make Initialization
Enter a name: x
Enter an integer value: 5
Result: int x = 5;


5. Fraction
Enter a numerator: 1
Enter a denominator: 2
Result: 0.5
