戻り値が配列の時

public class Main {

  public static int[] makeArray(int size) {
    //int[]で配列を作る
      int[] newArray = new int[size];
      for (int i = 0; i < newArray.length; i++ ) {
       newArray[i] = i;
      }
     return newArray;
  }

  public static void main(String[] args) {
//makeArray(3)を実行して
    int[] array = makeArray(3);
//結果を int i をarrayに変換する
    for (int i : array) {
      System.out.println(i);
    }
  }
