[ad_1] You forgot the ; before do. do counts as a new statement. Alternatively you could place the do on a new line. In my opinion, the most comfortable way to convert DOS line endings (CRLF) to Unix line endings (LF-only) is dos2unix. If you fix your ;error, using dos2unix instead of sed should be … Read more
[ad_1] You should first initialize you SQLiteDatabase, so convert this: SQLiteDatabase database; database.delete(ActivityTableDBOpenHelper.ACTIVITY_TABLE,null,null); to this: SQLiteDatabase database = new SQLiteDatabase(this); // or dbHelper.getWritableDatabase(); if you have a dbHelper database.delete(ActivityTableDBOpenHelper.ACTIVITY_TABLE,null,null); Else the database object is null and you get the error. Here you could find a whole example for all operations http://www.vogella.com/tutorials/AndroidSQLite/article.html 2 [ad_2] solved How … Read more

[ad_1] Of course you can run java programs on windows an linux, and you can make cross platform programs in java as long as your operating system has the java runtime on it, if not… it won’t run. You don’t need to code different for windows and for linux in java, maybe just some minor … Read more

[ad_1] to get all rows, just use select * from tableName If you want to filter the duplicates out just add select distinct * from tableName if you want to group by, you can do: select column1, column2 sum(column1, column2) as sumCol from table group by column1,column2 or using a window function select * sum(column1, … Read more

[ad_1] scanf() returns number of receiving arguments successfully assigned or EOF in case of failure. Read more about scanf() here. In context of your program, when you give input 5 the scanf() successfully assign it to receiving argument i and since the receiving argument is 1, scanf() is returning 1 which is getting printed. Hence … Read more
[ad_1] I would use data.table and do something like the following: library(data.table) setDT(df) ndf <- df[, .(Date = paste(Date[1], “to”, Date[.N]), weather = Type.of.Weather[1]), rleid(Type.of.Weather) ][, rleid := NULL ][] ndf Date weather 1: 01-Jan to 03-Jan Cloudy 2: 04-Jan to 10-Jan Rainy 3: 11-Jan to 15-Jan Cloudy 4: 16-Jan to 20-Jan Sunny 1 [ad_2] … Read more
[ad_1] Here is one way using arrays. Depending on the size of your data you may hit a limit with Transpose, in which case I can re-write part of the solution. I have used “,” delimiter to keep track of separate column items when concatenating together.You may wish to swop this with a symbol you … Read more
[ad_1] I made some slight modifications to the original code in order to make it use the amount of keys instead of the array values, and then I added a second function to allow a multi-dimensional array to be counted as well. <?php function everyCombination($array) { $newArray = array(); for($keyCount = 1; $keyCount <= count($array); … Read more
[ad_1] It’s quite easy using pandas and a dict: with open(‘file.txt’, ‘r’) as f: lines = f.readlines() students = [] student = {} for line in lines: if ‘:’ in line: student[‘id’] = line.split(‘:’)[0] elif ‘name’ in line: student[‘Name’] = line.split(‘=’)[1].replace(‘\n’,”) elif ‘Age’ in line: student[‘Age’] = line.split(‘=’)[1].replace(‘\n’,”) elif ‘Grade’ in line: student[‘Grade’] = line.split(‘=’)[1].replace(‘\n’,”) … Read more

[ad_1] As pointed out in comments, it’s most likely that input might be coming as string. You can easily parse Date from string like this: private static Date getDate(String dateStr) throws ParseException { SimpleDateFormat simpleDateFormat = new SimpleDateFormat(“ddMMyyyy”); return simpleDateFormat.parse(dateStr); } Then you can do something like this to check which date is older: String … Read more
