Given length and width of a rectangle and we have to find its perimeter using java program.
Formula to find perimeter of a rectangle: perimeter = 2 (Length + Width)
Example:
Input: Length: 25 Width: 22 Output: Perimeter = 2 (25+22) = 94
import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; public class CalPerimeterOfRectangle { public static void main(String[] args) { int width = 0; int length = 0; try { // create object of the buffer class. BufferedReader br = new BufferedReader(new InputStreamReader(System.in)); // enter length and width of the rectangle. System.out.print("Enter length of the rectangle : "); length = Integer.parseInt(br.readLine()); System.out.print("Enter width of the rectangle : "); width = Integer.parseInt(br.readLine()); } // check for invalid value. catch(NumberFormatException ne) { System.out.print("Invalid value" + ne); System.exit(0); } catch(IOException ioe) { System.out.println("IO Error :" + ioe); System.exit(0); } // formula to calculate parimeter. int perimeter = 2 * (length + width); System.out.print("Perimeter of a rectangle is : " + perimeter); } }
Output
Enter length of the rectangle : 25 Enter width of the rectangle : 22 Perimeter of a rectangle is : 94
