Problem:
Code(Class):
package rectanglePackage;
public class Rectangle {
double width, height; Rectangle(){ width =1; height =1; } Rectangle( double width, double height){ this .width= width; this .height= height; } double getArea() { return widthheight; } double getPerimeter() { return 2(width+height);
}
}
Code (Test):
package rectanglePackage;
public class Main { public static void printRect(Rectangle r) { System. out .println("For Rectangle 1: "); System. out .println("Width: "+ r + "\tHeight: " + r); System. out .println("Area: " + r() + "\tPerimeter: "

}
private getMonthlyInterestRate() { return (annualInterestRate / 100) / 12 ; }
private getMonthlyInterest() { return balance * getMonthlyInterestRate(); }
private withdraw( double amount) { this .balance -= amount; }
private deposit( double amount) { this .balance += amount; }
Code (Test):
package accountPackage;
public class Accountoutput { public static void main(String[] args) { Account account = new Account(1122, 20000); account(4); account(2500); account(3000); System. out .println("Balance: $" + account()); System. out .println("Monthly Interest: " + account()); System. out .println("Date Created: " + account());
} }
public RegularPolygon( int numberOfSides, double sideLength, double x, double y) { this (numberOfSides, sideLength); CenterX = x; CenterY = y; } //Accessor
public int getNumberOfSides() { return NumberOfSides; } //Modifier public void setNumberOfSides( int numberOfSides) { NumberOfSides = numberOfSides; } //Accessor public double getSideLength() { return SideLength; } //Modifier public void setSideLength( double sideLength) { SideLength = sideLength; }
public double getCenterY() { return CenterY; }
public void setCenterY( double centerY) { CenterY = centerY; }
public double getCenterX() { return CenterX; }
public void setCenterX( double centerX) { CenterX = centerX; }
public double getPerimeter(){
return NumberOfSides * SideLength; }
public double getArea() {
return (NumberOfSides * SideLength * SideLength) / (4 * Math. tan (Math. PI / NumberOfSides)); }
}
Code(Test):
package Polygon;
public class Main {
public static void main(String[] args) { // Create three RegularPolygon objects RegularPolygon regularPolygon1 = new RegularPolygon(); RegularPolygon regularPolygon2 = new RegularPolygon(4, 3); RegularPolygon regularPolygon3 = new RegularPolygon(8, 4, 6, 5);
// Display perimeter and area of each object System. out .println("Objects Perimeter Area"); System. out .printf( "1 %6 %5\n", regularPolygon1(), regularPolygon1()); System. out .printf( "2 %6 %5\n", regularPolygon2(), regularPolygon2()); System. out .printf( "3 %6 %5\n", regularPolygon3(), regularPolygon3()); } }
