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	TheReceptionist	653	Entertainment	424	13021	4.34	1305	744	DjdA-5oKYFQ	NxTDlnOuybo	c-8VuICzXtU	DH56yrIO5nI	W1Uo5DQTtzc	E-3zXq_r4w0	1TCeoRPg5dE	yAr26YhuYNY	2ZgXx72XmoE	-7ClGo-YgZ0	vmdPOOd6cxI	KRHfMQqSHpk	pIMpORZthYw	1tUDzOp10pk	heqocRij5P0	_XIuvoH6rUg	LGVU5DsezE0	uO2kj6_D8B4	xiDqywcDQRM	uX81lMev6_o";
        String [ ] array = s1.split("	");
        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!");
        }


    }
