Create a class rectangle The class has attributes length and width each of which is defaults to 1 It has member functions that calculates the perimeter and the area of the rectangle it has set?
public class Rect { private int width, height; public Rect() { width = height = 1; } public Rect(int w, int h) { width = w; height = h; } public int getWidth() { return width; } public int getHeight() { return height; } public void setWidth(int w) { width = w; } public void setHeight(int h) { height = h; } public int getPerimeter() { return 2 * (width + height); } public int getArea() { return width * height; } }
Example of area of rect inheritance program in java?
Let us first define a generic Shape class. This will be an abstract class, since the term "shape" is, itself, very abstract. Let us also assume that this shape is defined in only two dimensions, for the sake of simplicity. abstract class Shape { /* One of the properties of any 2D shape is the area it takes up. Since calculating the area depends on the shape, we'll make this method abstract - all subclasses should implement it differently. */ abstract int getArea(); } Now that we have our base class defined, we can create a rectangle subclass. class Rectangle extends Shape { /* While a rectangle has other properties, we are really only interested in the ones required to calculate the area - width and height. */ int width; int height; /* What's the area of a rectangular shape? area = width x height */ int getArea() { return width*height; } }
Write a program to demonstrate constructor overloading?
Constructor overloading is similar to method overloading. You can overload constructors by changing the parameter list in the class definition. Here is an example public class Box{ private int height; private int width; private int breadth; // First constructor with no parameters Box(){ height = 0; width = 0; breadth = 0; } // This is the second overloaded constructor Box(int h,int w,int b){ height = h; width = w; breadth = h; } public void display(){ System.out.println("Height: "+height+" Width: "+width+" Breadth: "+breadth); } public static void main(String args[]){ Box obj = new Box(1,2,3); obj.display(); } }
What is instantiating in java?
To instantiate is to create a new "instance" of an "object" in object-oriented programming. For example, say you create an Object by defining a class called Square: (note: this is C++ but the principles are the same) class Square{ private: int length, width; public: getArea(){return length*width); }; The above class is an Object. When you create this object, that is called an "instance" of the object: int main() { Square x = new Square; // x is an "instance" of the Square "object" Square y = new Square; // y is a separate "instance" of the Square "object" return 0; }

Is the any Correlation between class width and student achievement?
There is no correlation between class width and student achievement. Class width is arbitrary (there are rules of thumb for class width, and it depends on the range of the data).
What does class width mean?
Class width refers to the range of values in a single class or interval in a frequency distribution. It is calculated by subtracting the lower boundary of a class from its upper boundary. For example, if a class ranges from 10 to 20, the class width would be 10. Class width is important for organizing data into manageable groups for analysis and visualization.
What century is 7000-7999?
The years 7000 to 7999 belong to the 71st century. In the Gregorian calendar, centuries are counted by grouping years into sets of 100, so the year 7000 marks the beginning of the 71st century, which will end in the year 7999.
What is upper class width in statistics?
In statistics, the upper class width refers to the range of values in a specific class interval of a frequency distribution. It is the maximum value that can be included in that class interval. For example, if a class interval is defined as 10-20, the upper class width would be 20. Understanding upper class width is essential for accurately summarizing and analyzing data in histograms and other statistical representations.
What is the width of the seats on American Airlines?
The width of the seats on American Airlines varies depending on the aircraft and class of service. Generally, the width of the seats in economy class ranges from 17 to 18 inches, while in business and first class, the width can be up to 21 inches or more.
