Answer:

if (x > 7 && Math.sqrt(x) < 3)

Explanation:

The previous condition checks if the square root of x is less than 3, but this would raise an error if x is a value equal to or less than 0.

So, the condition checks for the value of x before evaluating the square root after the AND operation to prevent an arithmetic exception.

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();

}
