eclipse经常出现“indexing jar types”是怎么回事啊?该怎么处理? 2C

图片说明
一直卡到图片这个界面,0%的进度;
求给解释下,indexing jar types 是在什么时候会触发,以及,这种情况可能会出现的原因。
补充:
经过观察,发现是编辑workspace以外的项目,编辑java文件,自动代码提示的时候,会触发这种情况,并且在网络不好的时候会卡死。

原因我搞的不是很明白:但是我已经有了一个很好的解决办法了:
Preferences->Java->Editor->Content Assist->Advanced
把Jar Type Search 去掉就好了

2个回答

把你的jdk重装下,以及把你的eclipse也删除再拷贝下。清除掉workspace试试看

我看你这个现象怎么像是jar包冲突啊,比如说:v4和v7

Win7 打开windows功能中 Indexing Service 失败

1.背景 因安全要求,新安装 Win7 32位系统,Office 2016,Visio 2016。经常使用Visio ,搜索功能很方便,但是新安装后无法启用搜索功能,查询攻略,找到原因,需启动Windows功能中第一项:Indexing Service。 2.描述 点击复选框后,等待启用该功能,却弹出错误提示菜单:出现错误,并非所有的功能被成功更改! 3.尝试办法 更改通知设置为不通知模式,不管用,重启不管用,更改C盘用户权限为完全控制,还是不管用。同时,发现设置Internet服务 web核心服务,两项功能也不能选,貌似所有的功能都不能更改。 求助各位大侠!

Eclipse PyDve 运行 matplotlib 报错

如题,Eclipse PyDve 运行 matplotlib 报错 就一行简单的代码 import matplotlib.pyplot as plt: ![图片说明](https://img-ask.csdn.net/upload/201506/08/1433741894_588471.jpg) 根据报错,找到了出错的原因是 ImportError: cannot import name Random 也就是不能 import Random 但是同样的代码在 python 里面跑就是正常的: ![图片说明](https://img-ask.csdn.net/upload/201506/08/1433742066_614992.jpg) 我把路径都设置正确了,random.py 就在 C:\python27\lib 里,同样存在 C:\python27\lib 中的其他文件都可以被正常使用 甚至random.py模块也可以在eclipse中显示,并且其中就有 class Random: ![图片说明](https://img-ask.csdn.net/upload/201506/08/1433742431_461586.jpg) 但是eclipse就是查不到,还显示 unresolved import

Document Indexing

Andy is fond of old computers. He loves everything about them and he uses emulators of old operating systems on his modern computer. Andy also likes writing programs for them. Recently he has decided to write a text editor for his favorite text-mode operating system. The most diffcult task he has got stuck with is document indexing. An index of the document is the lexicographically ordered list of all words occurring in the document with the numbers of pages they occur at. Andy feels that he is not able to write the component of the editor that performs indexing, so he asks you to help. A document is a sequence of paragraphs. Each paragraph consists of one or more lines. Paragraphs are separated from each other with exactly one blank line. First, the document is paginated --- divided into pages. Each page consists of up to n lines. Lines are placed on the page one after another, until n lines are placed. The following correction rules are then applied: If the last line on a page is the last line of the paragraph, then the following empty line is skipped, i.e. it is not placed on any page. Therefore, the page never starts with a blank line. If the last line on a page is the first line of a paragraph that contains more than one line (so called orphan line), then it is moved to the next page. If the last line on a page is the next-to-last line of a paragraph that contains more than three lines, then this line is moved to the next page (otherwise, the last line of the paragraph would be alone on the page --- so called widow line). If the last line on a page is the next-to-last line of a paragraph that contains exactly two or three lines, then the whole paragraph is moved to the next page (so we have neither orphan, nor widow lines). After applying the correction rules the next page is formed, and so on until the whole document is paginated. A word is a continuous sequence of letters of the English alphabet. Case is not important. The index of the document contains each word from the document and the list of the pages it occurs at. The numbers of pages a word occurs at must be listed in the ascending order. Numbers must be separated by commas. If a word occurs on three or more consecutive pages, only the first and the last page numbers of this range must be listed, separated by a dash, for example "35,710,12,13,15". Input There are several test cases in the input. The first line of each case contains n (4 ≤ n ≤ 100). The rest of the input file contains the document to be indexed. The size of the input file does not exceed 20 000 bytes. The line is considered blank if it is completely empty. No line contains leading or trailing spaces. The document does not contain two consecutive blank lines. The first line of the document is not blank. The length of each line of the document does not exceed 200 characters. Output Print all words that occur in the given document. Words must be printed in the lexicographical order, one word on a line. After each word print one space followed by the list of pages it occurs at, formatted as described in problem statement. Use capital letters in output. Sample Input 6 From thousands of teams competing in regional contests held from September to December 2004 world-wide, seventy-five teams will advance to the World Finals in Shanghai, April 3-7, 2005. Awards, prizes, scholarships, and bragging rights will be at stake for some of the world's finest university students of the computing science. Join us for the challenge, camaraderie, and the fun!

Soundex Indexing

Problem Description The Soundex Index System was developed so that similar sounding names, or names with similar spelling could be encoded for easy retrieval. It has been used by the U.S. Bureau of the Census, and some States use it to help encode your driver's license number. Your task is to read a sequence of names, one at a time and one per line, compute the corresponding soundex code, and write to the output file the name and its soundex code (one line of output per name). Names will contain from 1 to 20 upper case, alphabetic characters (ASCII values 65 thru 90, inclusive). Names shorter than 20 characters will NOT be padded with blanks. Thus a narne will consist of upper case letters only. How to generate the Soundex Code: A Soundex Code always consists of a letter followed by three digits. Here are the rules for soundex encoding: 1. The first letter of a name appears as the first and only letter in the soundex code. 2. The letters A, E, I, O, U, Y, W, & H are never encoded, but do break successive code sequences (see next rule). 3. All other letters are encoded EXCEPT when they immediately follow a letter (including the first letter) that would be encoded with the same code digit. 4. The soundex code guide is: 5. Trailing zeros are appended to short codes so all names are encoded with a letter followed by three digits. 6. Longer codes are truncated after the third digit. Input The input file, SOUNDEX.IN, contains a list of names, one per line. Each name will not exceed 20 characters, and you may assume that only upper case letters will be used. Your program should continue to read names until the end of the file is detected. Output The output written to the file SOUNDEX.OUT should consist of a column of names and a column of their corresponding soundex codes. Write the headings "NAME" and "SOUNDEX CODE" in the first line of the output file in columns 10 and 35, respectively. After the heading line, the names and soundex codes should be written (one pair per line) with the name starting in column 10 and the soundex code beginning in column 35. The comment "END OF OUTPUT" should appear at the end of the output file on the line immediately after the last name. This comment should be written starting in column 20. Sample Input LEE KUHNE EBELL EBELSON SCHAEFER SCHAAK Sample Output NAME SOUNDEX CODE LEE L000 KUHNE K500 EBELL E140 EBELSON E142 SCHAEFER S160 SCHAAK S200 END OF OUTPUT | | | | | |__ Column 35 | |__ Column 20 |__ Column 10
