Java示例使用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+ " ");

      }

   }

}
