In this lab, you will create a programmer-defined class and then use it in a Java program. The program should create two Rectang

prohojiy [21]

Answer:

class Rectangle{

//private attributes of length and width

private double givenLength;

private double givenWidth;

// constructor to initialize the length and width

public Rectangle(double length, double width){

givenLength = length;

givenWidth = width;

}

// setter method to set the givenlength

public void setGivenLength(double length){

givenLength = length;

}

// setter method to set the givenWidth

public void setGivenWidth(double width){

givenWidth = width;

}

// getter method to return the givenLength

public double getGivenLength(){

return givenLength;

}

// getter method to return the givenWidth

public double getGivenWidth(){

return givenWidth;

}

// method to calculate area of rectangle using A = L * B

public void calculateArea(){

System.out.println("The area of the rectangle is: " + getGivenLength() * getGivenWidth());

}

// method to calculate perimeter of rectangle using P = 2 * (L + B)

public void calculatePerimeter(){

System.out.println("The perimeter of the rectangle is: " + 2 * (getGivenLength() + getGivenWidth()));

}

public class MyRectangleClassProgram{

public static void main(String args[]){

//rectangle1 object is created

Rectangle rectangle1 = new Rectangle(10.0, 5.0);

//rectangle2 object is created

Rectangle rectangle2 = new Rectangle(7.0, 3.0);

//area for rectangle1 is calculated

rectangle1.calculateArea();

//perimeter for rectangle1 is calculated

rectangle1.calculatePerimeter();

//area for rectangle2 is calculated

rectangle2.calculateArea();

//perimeter for rectangle2 is calculated

rectangle2.calculatePerimeter();

}

Given that Jamie worked 50 hours (Hours = 50) last week and earns $10.00 an hour (Rate = 10), how much did Jamie earn last week,

quester [9]

Answer:

Jamie earned (Total pay) $500.

Explanation:

We are given the following code:

If (Rate >=10) OR (Hours <=40) Then

TotalPay = Hours * Rate

Else

TotalPay = (Hours * Rate)+(Hours–40)*Rate*1.5

End If

Let us understand the code line by line:

The first line contains an if statement with 2 conditions:

i.e. 1st condition:

The rate is greater than or equal to 10

2nd condition:

Number of hours are lesser than or equal to 40.

There is OR between the two condition i.e. the statement next to if() statement will get executed if any one of them becomes true and else part will not be executed.

The next statement is:

TotalPay = Hours * Rate

It calculates the pay if any of the two conditions written earlier becomes true.

Next statement is else statement:

It will get executed given that the above if() statement becomes false.

Now, we are given that Jamie worked 50 hours last week and earns $10.00 an hour:

i.e.

Hours = 50

Rate = 10

Now, let get to the code execution.

The first condition is true i.e. Rate >= 10 (because Rate is 10 here)

So, the following statement will be used to calculate the Total pay:

TotalPay = Hours * Rate

and else part will not be executed.

TotalPay = 50 * 10 = $500

Jamie earned (Total pay) $500.

Write a method that prints on the screen a message stating whether 2 circles touch each other, do not touch each other or inters

beks73 [17]

Answer:

The method is as follows:

public static void checkIntersection(double x1, double y1, double r1, double x2, double y2, double r2){

double d = Math.sqrt(Math.pow((x1 - x2),2) + Math.pow((y1 - y2),2));

if(d == r1 + r2){

System.out.print("The circles touch each other"); }

else if(d > r1 + r2){

System.out.print("The circles do not touch each other"); }

else{

System.out.print("The circles intersect"); }

}

Explanation:

This defines the method

public static void checkIntersection(double x1, double y1, double r1, double x2, double y2, double r2){

This calculate the distance

double d = Math.sqrt(Math.pow((x1 - x2),2) + Math.pow((y1 - y2),2));

If the distance equals the sum of both radii, then the circles touch one another

if(d == r1 + r2){

System.out.print("The circles touch each other"); }

If the distance is greater than the sum of both radii, then the circles do not touch one another

else if(d > r1 + r2){

System.out.print("The circles do not touch each other"); }

If the distance is less than the sum of both radii, then the circles intersect

else{

System.out.print("The circles intersect"); }

}

Which of the following enables robots to do things such as understand itself, walk, talk, and develop skills?

zmey [24]

Answer:

self-modeling

Explanation:

Robots, which are man-made machines which mimics the actions of man like walking, talking, rendering assistance are part of the future plans to make the society easier. It was mans' attempt to improve the society but still happens to be work in progress.

For the robots to be able to carryout its function, there is need for it to be self modelling in the sense of initiating and executing the commands which was already programmed into it. For example, telling it to walk will be initiated by him as a command, after processing the command, it will execute it without any other information.
