simplecollection.java

一些基本的java程序源代码

package simpleobject;

public class SimpleCollection {
			private Object[] objArr;
			private int index=0;
			public SimpleCollection(){
				objArr=new Object[10];
			}
			public SimpleCollection(int capacity){
				objArr=new Object[capacity];
			}
			public void add(Object o){
				objArr[index]=o;
				index++;
			}
			public int getLength(){
				return index;
			}
			public Object get(int i){
				return objArr[i];
			}
}
