Lets say I have to use an if statement within a for loop and the for loop fires at a certain condition and the if statement only fires when the for loop has reached a certain stage. For example, the condition is a counter that counts up when a certain thing happens such as a ball falling down the screen. circles are drawn one by one everytime the ball crosses the screen. When the circles in the first row have reached the end of the screen, the circles start appearing on the second row below the first one. However the second row isnt working for me, which I have implemented with the if

环境简述 两个实例，源库为non-CDB，目标为CDB。版本均为19.3。位于同一台主机。 实验将non-CDB迁移到CDB中的PDB：hr_pdb中 实验过程 确认平台和字节序是一样的： SELECT d . PLATFORM_NAME , ENDIAN_FORMAT FROM V$TRANSPORTABLE_PLATFORM tp , V$ DATABASE d WHERE tp . PLATFORM_ID = d . PLATFORM_ID ; PLATFORM_NAME ENDIAN_FORMAT -------------------- -------------- Linux x86 64 - bit Little 确认表空间是自包含的： ORCLCDB2 > EXECUTE DBMS_TTS . TRANSPORT_SET_CHECK ( 'users' , TRUE ) ; PL / SQL procedure successfully completed . ORCLCDB2 > SELECT * FROM TRANSPORT_SET_VIOLATIONS ; no rows selected 创建Directory: ORCLCDB2 > CREATE DIRECTORY dp_dir AS '/u01/app/datafiles' ; Directory

So the idea here is that I'm taking a .csv into a string and each value needs to be stored into a variable. I am unsure how to properly parse a string to do this. My idea is a function that looks like final char delim = ','; int nextItem(String data, int startFrom) { if (data.charAt(startFrom) != delim) { return data.charAt(startFrom) } else { return nextItem(data, startFrom + 1); } } so if I passed it something like nextItem("45,621,9", 0); it would return 45 and if I passed it nextItem("45,621,9", 3); it would return 621 I'm not sure if I have that setup properly to be recursive, but I could

作者Michael G. Noll是瑞士的一位工程师和研究员，效力于Verisign，是Verisign实验室的大规模数据分析基础设施（基础Hadoop）的技术主管。本文，Michael详细的演示了如何将Kafka整合到Spark Streaming中。 期间， Michael还提到了将Kafka整合到 Spark Streaming中的一些现状，非常值得阅读，虽然有一些信息在Spark 1.2版本中已发生了一些变化，比如HA策略： 通过Spark Contributor、Spark布道者陈超我们了解到 ，在Spark 1.2版本中，Spark Streaming开始支持fully HA模式（选择使用），通过添加一层WAL（Write Ahead Log），每次收到数据后都会存在HDFS上，从而避免了以前版本中的数据丢失情况，但是不可避免的造成了一定的开销，需要开发者自行衡量。 以下为译文 作为一个实时大数据处理工具， Spark Sreaming 近日一直被广泛关注，与 Apache Storm 的对比也经常出现。但是依我说，缺少与Kafka整合，任何实时大数据处理工具都是不完整的，因此我将一个示例Spark Streaming应用程序添加到 kafka-storm-starter ，并且示范如何从Kafka读取，以及如何写入到Kafka。在这个过程中

I want to achieve a slow fade in size on every collapse into itself. In other words, when the circle is at its biggest, the ellipses will be at the largest in size and conversely the opposite for the retraction. So far I am trying to achieve this affect by remapping the cSize from the distance of the center point, but somewhere along the way something is going wrong. At the moment I am getting a slow transition from small to large in ellipse size, but the inner ellipses are noticeably larger. I want an equal distribution of size amongst all ellipses in relation to center point distance. I've

I'm a newbie programmer practicing Processing and I recently developed a sketch that uses Twitter4j. When I run the sketch in Java mode from the Processing Development Environment it works perfectly. Also, when I export the sketch from Java mode the resulting application runs perfectly. However, when I switch to JavaScript mode and try to run the sketch the browser preview does not display anything. I believe the problem is related to Twitter4j because when I remove the Twitter4j-related code from the sketch and run it (in JavaScript mode) the browser preview then displays the Processing

void setup() { size(600, 480, P3D);hint(ENABLE_DEPTH_SORT); } void draw() { background(0); translate(width/2, height/2); fill(color(255,255,255),84); strokeWeight(0); translate(-40,0,1);sphere(80); translate(2*40,0,0);sphere(80); // Fails with corruption: http://i.imgur.com/GW2h7Qv.png } Note: sphereDetail need not apply. sphereDetail(60) causes fail with loss of left overlap: To understand why this is happening, you have to understand what's going on under the hood. Think in Triangles When you call the sphere() function, Processing is actually drawing a bunch of triangles. You can see this if
