I did this java program, i just want someone to correct it.
In this exercise, you will be writing a simple java program to explore using multi methods. The program is consists of one class (MultiMethods). It will hold more than one methods. The purpose of the program is to calculate and display the volume, area, and perimeter of a cube. The length of the cube will be collected from the keypad. For each calculation, you must have a corresponding method. As such, your program will have 4 methods including the main() method.
my java program is
public static void main(String[] args) {
Scanner in= new Scanner(System.in);
System.out.println("Enter the length: ");
int side = in.nextInt();
multimethods Methods = new multimethods(side);
System.out.println("Area = " + Methods.getArea());
System.out.println("Perimeter = " + Methods.getPerimeter());
System.out.println("Volume = " + Methods.getvolume());
}
public static class multimethods {
private final int side;
multimethods(int side) {
this.side = side;
}
double getArea() {
return 6 * (side * side);
}
double getPerimeter() {
return 4 * (side);
}
double getvolume(){
return side * side * side;
}
}
looks basically ok.
I think your class declaration is messed up though.
Did you actually run it?
google is your friend. You can use it to find many code snippets online, doing practically anything you can want. And don't forget the excellent java documentation.
yes i did run it and it works normal
well, then, I guess you're ok, right?
Your Java program to calculate the volume, area, and perimeter of a cube is mostly correct. However, there are a few improvements you can make:
1. Import the Scanner class: You need to import the Scanner class at the beginning of your program. Add the following line at the top, before the class declaration:
```java
import java.util.Scanner;
```
2. Capitalize class name: In Java, class names should start with a capital letter. Change the class name from "multimethods" to "MultiMethods" for consistency.
3. Rename the object: Conventionally, object names should start with a lowercase letter. Change `Methods` to `methods` to follow this convention.
4. Improve readability: You can add some formatting to the output statements to make them more readable. For example, you can add spaces after the equal sign and before the units.
Here's the corrected version of your program:
```java
import java.util.Scanner;
public class MultiMethods {
private final int side;
public MultiMethods(int side) {
this.side = side;
}
public double getArea() {
return 6 * (side * side);
}
public double getPerimeter() {
return 4 * side;
}
public double getVolume() {
return side * side * side;
}
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.print("Enter the length: ");
int side = in.nextInt();
MultiMethods methods = new MultiMethods(side);
System.out.println("Area = " + methods.getArea());
System.out.println("Perimeter = " + methods.getPerimeter());
System.out.println("Volume = " + methods.getVolume());
}
}
```
With these changes, your program should work correctly.
