数组的定义（两种）

public class TestArray {
 public static void main(String arg[]){
  int[] list = {1,2,3,4,5,6};
  int[] lists = new int[3];
  int i;
  lists[0] = 2;
  lists[1] = 6;
  lists[2] = 5;
  for(i=0;i<list.length;i++){
   System.out.println(list[i]);
  }
 }
}

public class TestArray {
   public static void main(String[] args) {
      double[] myList = {1.9, 2.9, 3.4, 3.5}; // 打印所有数组元素
      for (double j: myList) {
         System.out.println(element);
      }
   }
