寻找矩形周长的 Java 程序

原文:https://www . geeksforgeeks . org/Java-program-to-find-a-period-of-a-a-rectangle/

A 矩形是四个直角(90°)的四边形。在矩形中,相对的边是相等的。四边相等的长方形叫做正方形。矩形也可以称为直角平行四边形。

矩形

在上面的矩形中,边 AC 相等,边 BD 相等。

矩形的周长是其所有四条边的总长度。它可以简单地用它的四个边来计算。

Perimeter of rectangle ABCD = A+B+C+D

由于矩形中相对的边相等,它可以计算为其一边的两倍和其相邻边的两倍之和。

Perimeter of rectangle ABCD = 2A + 2B = 2(A+B)

程序

Java 语言(一种计算机语言,尤用于创建网站)

// Java program to find the perimeter of a Rectangle

import java.io.*;

class GFG {

    // Method to calculate the perimeter of the rectangle
    // with given length and breadth
    static void perimeter(int length, int breadth)
    {
        // Calculate the 'perimeter' using the formula
        int perimeter = 2 * (length + breadth);

        System.out.println("The perimeter of the given rectangle of length "
            + length + " and breadth " + breadth + " = "
            + perimeter);
    }

    // Driver method
    public static void main(String[] args)
    {
        // Initialize a variable length that stores length of
        // the given rectangle
        int length = 10;

        // Initialize a variable breadth that stores breadth
        // of the given rectangle
        int breadth = 20;

        // Call the perimeter method on these length and
        // breadth
        perimeter(length, breadth);
    }
}

Output

The perimeter of the given rectangle of length 10 and breadth 20 = 60
