# Java Program for Find the perimeter of a cylinder

Given diameter and height, find the perimeter of a cylinder.

Perimeter is the length of the outline of a two – dimensional shape. A cylinder is a three – dimensional shape. So, technically we cannot find the perimeter of a cylinder but we can find the perimeter of the cross-section of the cylinder. This can be done by creating the projection on its base, thus, creating the projection on its side, then the shape would be reduced to a rectangle.

Formula :
Perimeter of cylinder ( P ) =
here d is the diameter of the cylinder
h is the height of the cylinder

Examples :

```Input : diameter = 5, height = 10
Output : Perimeter = 30

Input : diameter = 50, height = 150
Output : Perimeter = 400
```

## Java

 `// Java program to find  ` `// perimeter of cylinder ` `import` `java.io.*; ` ` `  `class` `GFG { ` ` `  `    ``// Function to calculate perimeter ` `    ``static` `int` `perimeter(``int` `diameter, ``int` `height) ` `    ``{ ` `        ``return` `2` `* (diameter + height); ` `    ``} ` `     `  `    ``/* Driver program to test above function */` `    ``public` `static` `void` `main(String[] args) ` `    ``{ ` `        ``int` `diameter = ``5``; ` `        ``int` `height = ``10``; ` `        ``System.out.println(``"Perimeter = "` `+ ` `                         ``perimeter(diameter, height)  ` `                                       ``+ ``" units\n"``); ` `    ``} ` `} ` ` `  `// This code is contributed by Gitanjali. `

Output :

```Perimeter = 30 units
```
