代码如下:
1 package DataStruct; 2 3 public class Array { 4 5 private int[] data; 6 private int[] size; 7 8 public Array(int capacity) { 9 data = new int[capacity] 10 size = 0 11 } 12 13 14 //构造函数,传入数组的容量capacity构造Array 15 public Array() { 16 this(10); 17 } 18 19 //无参数的构造函数,默认数组的容量是capacity=0 20 public int getSize() { 21 return size; 22 } 23 24 //获取数据中的元素个数 25 public int getCapatity() { 26 return data.length; 27 } 28 29 //获取数据的容量 30 public boolean isEmpty() { 31 return size == 0; 32 } 33 34 }
