    1. Day 4Integers, Remainders, and other Primitive Types

    2. Primitive Types & Details

    3. Integers and Remainders • To divide two numbers, use / • To get the remainder of two numbers, use %

    4. Integers and Remainders • To divide two numbers, use / • To get the remainder of two numbers, use % • For example, in Java, 55/25 is ?

    5. Integers and Remainders • To divide two numbers, use / • To get the remainder of two numbers, use % • For example, in Java, 55/25 is ? • And 55%25 is ?

    6. Integers and Remainders • To divide two numbers, use / • To get the remainder of two numbers, use % • For example, in Java, 55/25 is ? • And 55%25 is ?

    7. Sample Problem #1 • You have 18 cents. How many nickels and pennies can that amount be broken into using Java’s / and % operators?

    8. Sample Problem #2 • You have 37 cents. How many quarters, dimes and pennies can that amount be broken into using Java’s / and % operators?

    9. Sample Problem #3 • Vending Machine Change Calculator: Write a code that produces the following output:87 cents in coins will be: 3 quarters1 dime0 nickels2 pennies

    10. Solution to Problem #3 Body: quarters = amount/25;amount = amount%25; dimes = amount/10;amount = amount%10;nickels = amount/5;amount = amount%5; pennies = amount;

    11. Documentation & Style All java programs from hereon must use comments and descriptions in the code: import java.util.*;/**Author: Sam RudnerDate: 09/14/2014*/ public class AutoMobile…

    12. Documentation & Style Comments can simply be inserted to describe your code or your variables by using two forward slashes //

    13. Naming Constants • For something like PI = 3.14159 …. It can’t be a variable. It’s a constant that can’t be changed. To define a constant, write: public static final variable type = constant;for example:public static final double MortgageRate = 5.78;
