今天上了一天课

每日随笔

1.安装完idea之后, 若电脑没有安装jdk8.0 ,那么会自带安装11.0 ,这样会造成很多早期jar包不兼容

　　旧的java程序将无法找到所需要的包.详见Clean类

2. 拆分长类型-(Youtube视频各个信息,此处仅提取相关视频id的内容)

package com.company;

public class Main 

    public static void main(String[] args) 
        String s1 = "LKh7zAJ4nwo\\tTheReceptionist\\t653\\tEntertainment\\t424\\t13021\\t4.34\\t1305\\t744\\tDjdA-5oKYFQ\\tNxTDlnOuybo\\tc-8VuICzXtU\\tDH56yrIO5nI\\tW1Uo5DQTtzc\\tE-3zXq_r4w0\\t1TCeoRPg5dE\\tyAr26YhuYNY\\t2ZgXx72XmoE\\t-7ClGo-YgZ0\\tvmdPOOd6cxI\\tKRHfMQqSHpk\\tpIMpORZthYw\\t1tUDzOp10pk\\theqocRij5P0\\t_XIuvoH6rUg\\tLGVU5DsezE0\\tuO2kj6_D8B4\\txiDqywcDQRM\\tuX81lMev6_o";
        String [ ] array = s1.split("\\t");
        try
            for (int i = 9; i <s1.length();i++) 
                System.out.println(array[i]);
            
        
        catch (Exception ArrayIndexOutOfBoundsException)
            System.err.println("指针溢出但是无大碍!");
