java删除数组中的元素

在阅读tomcat4源码中发现删除数组中的元素的方法，记录一下。

 private Service services[] = new Service[0];
 public void removeService(Service service) {

        synchronized (services) {
            int j = -1;//删除元素在数据中的 索引
            for (int i = 0; i < services.length; i++) {
                if (service == services[i]) {
                    j = i;
                    break;
                }
            }
            if (j < 0)
                return;
            if (services[j] instanceof Lifecycle) {
                try {
                    ((Lifecycle) services[j]).stop();
                } catch (LifecycleException e) {
                    ;
                }
            }
            int k = 0;
            Service results[] = new Service[services.length - 1];
            for (int i = 0; i < services.length; i++) {
                if (i != j) //遍历数组元素不为要删除数组元素索引的 保存
                    results[k++] = services[i];
            }
            services = results;

            // Report this property change to interested listeners
            support.firePropertyChange("service", service, null);
        }

    }
