Java 使用for 和 foreach 循环

public class Main {
   public static void main(String[] args) {
      int[] intary = { 1,2,3,4};
      forDisplay(intary);
      foreachDisplay(intary);
   }

   public static void forDisplay(int[] a) {  
      System.out.println("Display an array using for loop");
      for (int i = 0; i < a.length; i++) {
         System.out.print(a[i] + " ");
      }
      System.out.println();
   }

   public static void foreachDisplay(int[] data) {
      System.out.println("Display an array using for each loop");
      for (int a  : data) {
         System.out.print(a+ " ");
      }
   }
}
