Why does this code give me an error?

[tawny quartz]

I am trying to train for java, but this code outputs an error

What is wrong?

public class main{
  public static int[] invert(int[] array) {
    for (int number : invert) {
      new_int.add(number*-1);
    }
    return new_int[]{};
  }
}

Detected code, here are some useful tools:

Formatted code

public class main {
  public static int [] invert(int [] array) {
    for (int number : invert) {
      new _int .add(number *  - 1);
    }
    return new _int [] {
    };
  }
}

Helper please have a look, thanks.

The issue in the code is that the for loop is incorrectly attempting to iterate over the array 'invert' instead of 'array'. To fix this, change 'for (int number : invert)' to 'for (int number : array)'.

It's an array and not a list. Therefore it has no methods like 'add'

[tawny quartz]

ahhh

Changed the category to Java.

You have three different names here

[unkempt belfry]

also new_int and invert doesnt exist here

[tawny quartz]

its on codewars

i just copied the code

[shy spire]

It's mostly nonsense.

[tawny quartz]

well thats what i got

Invert, for a number, means find it's reciprocal. And doing that on an int is going to end poorly.
