Help! Enhanced For loop practice

Question

P
Your company is writing a program for a geometry course.
The program takes the number of squares as the first input, creates an array, and then takes the sides of squares as its elements.
Write the part of the program that receives a list of square sides and prints the area of those squares for the user.

Sample Input
2
3
4

Output
9
16

Explanation
In this example we have 2 squares (the first input) and their sides accordingly - 3 and 4 (the second and the third inputs). The area of the first square is 9 (3*3), the second one 16 (4*4).

import java.util.Scanner;

public class Main {

public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
int length = scanner.nextInt();
int[] sides = new int[length];
for (int i = 0; i < length; i++) {
sides[i] = scanner.nextInt();
}
//your code goes here

}

Answer 1

import java.util.Scanner;

public class Main {

public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
int length = scanner.nextInt();
int[] sides = new int[length];
for (int i = 0; i < length; i++) {
sides[i] = scanner.nextInt();
}
//your code goes here

for(int s: sides){
System.out.println(s*s);
}

}
}

It works.

Answer 2

Can i ask were is this code from? Seen it twice this week

Answer 3

My guess would be that it is the practice 23.2 Geometry Code from the Java course.

Answer 4

Maybe share all of your current code and we can help you further.

My guess is that you're missing a closing curly brace }

My suggestion would be that you start your own post for your issue. Be sure to include detailed information on what the language, course, module project, etc and copy your current code to the playground and share a link to it in your post. Be sure to give input and output examples. Your question should be about whatever your problem is, whether there is something your don't understand, there are errors, the output isn't as expected etc. The better the description of the issue(s) the more likely you'll receive a proper response.
Remember in the future, don't hijack other users posts for your own questions.

Answer 6

for (int side: sides) {
...
...
}

Answer 7

Its from Java course. when i try to run for(int side:sides) it days illegal i dont know why.

Answer 8

I'm stuck on this one too
still no solution ?

Answer 9

import java.util.Scanner;

public class Main {

public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
int length = scanner.nextInt();
int[] sides = new int[length];
for (int i = 0; i < length; i++) {
sides[i] = scanner.nextInt();
}
//your code goes here

for(int s: sides){
System.out.println(s*s);
}

}
}

It works.

It worked for me too. But somehow it seems not right. I used the same code on Eclipse and doesn't work the same way. Maybe is the translation to Spanish of what they ask us for.
