有意思的可变数组依据tomcat生命周期的lifeSupport

依据tomcat源码中的LifecycleSupport.addLifecycleListener
package com.array;

public class ArrayTest {
	private static String str1[] = new String[0];
	public static void main(String[] args) {
		for (int i = 0; i < 10; i++)
			testArrayExtend(i + "");

	}

	private static void testArrayExtend(String args) {
		
		String str2[] = new String[str1.length + 1];
		for (int i = 0; i < str1.length; i++) {
			str2[i] = str1[i];
		}
		str2[str1.length] = args;
		str1 = str2;
		System.out.println(str1.length);
	}
}
