Java : Storing Data in Array Of Object from JOptionPane Dialog

- by Bader

hi guys i need to know how i can insert data inside objects inside an array of objects using my already made Set methods. i need to know how should i do it through user , i mean JOptionPane input dialog [code] student[] s=new student[5]; for (int i=1 ; i <= s.length ;i++) { s[i] = new student(i,"AAA","Ecommerce",0.0); } for (int i=1; i<=s.length;i++) { name = JOptionPane.showInputDialog("Please Write Name for student n " + i); major = JOptionPane.showInputDialog("Please Write Major for student n " + i); gpa =Double.parseDouble(JOptionPane.showInputDialog("Please Write GPA for student n " +i)); s[i]=new student(i,name,major,gpa); } [/code] i tried to do vars here that get data from user by JOptionPane, but it seems that i only use my already made constructor , not the Set methods. i need to use the methods because it has some validation code inside it. any ideas ?

adress-chunk: separate data stored in one collumn - into three (street, postal-code, town)

- by zero

hello dear community. Hello dear friends form all over the planet first of all - this is a great great forum. I like this place to share the ideas. It is so great to see such a supportive place - featuring the knowledge exchange! today i have the following thing to discuss: i want to separate the following data that are stored in one column of a calc-spreadsheet: See the following data: You see that there are the following categories:_ steet, postal-code, town All the data are stored in only one Colum; Well to be honest: i want to separate them into three colums steet, postal-code, town see the data: what can i do? note - you see that there are commas inbetween the enties: and besides this we see that we have a postal-code with four digits: that is a good thing. Perhaps we can use this as a marker that helps us to separate the data?! Perhaps See a data-sample! Here you can see some exceptions: eg. the town that has two words combinde with a "-" ... or somethims without any signs and characters... see the following... as an example: Max-Bader-Platz 1, 5620 Schwarzach im Pongau Pestalozzistraße 4, 9990 Nussdorf-Debant Schulstraße 4, 5162 Obertrum am See But i guess that this means no problem... What do you think about this? I am very very interested to get your opinion! i look forward to hear from you! regards see a snipped of the dataset - that is stored in one column -[b]Goal: [/b]i want to separate the datas into three collumns... : Schulweg 6, 9871 Seeboden Khevenhüllerstraße 45, 4861 Schörfling Franz Xaver Rennstr.18, 6460 Imst Schulstraße 4, 5162 Obertrum am See Schulweg 6, 7432 Oberschützen Pestalozzistraße 4, 9990 Nussdorf-Debant Niederndorf bei Kufstein 53c, 6342 Niederndorf bei Kufstein Hauptschulstraße 18, 2183 Neusiedl an der Zaya Seeweg 14, 5202 Neumarkt am Wallersee Europaplatz 1, 8820 Neumarkt in Steiermark Schulstraße 7, 4212 Neumarkt im Mühlkreis Schulstraße 20, 4720 Neumarkt im Hausruckkreis Bahnhofstr. 10, 4872 Neukirchen an der Vöckla Schulstraße 5b, 4780 Schärding Reitbergstraße 2, 4311 Schwertberg Europaplatz 1, 2320 Schwechat Am Schulberg 5, 3931 Schweiggers Waidach 8, 6130 Schwaz Waidach 8, 6130 Schwaz Max-Bader-Platz 1, 5620 Schwarzach im Pongau Markt 29, 2662 Schwarzau im Gebirge Hofsteigstraße 68, 6858 Schwarzach Gmundner Straße 7, 4690 Schwanenstadt Mühlfeldstraße 1, 4690 Schwanenstadt Mainsdorferstraße 18, 8541 Schwanberg Jakob Stemer-Weg 3, 6780 Schruns Obere Umfahrungsstraße 16, 2432 Schwadorf bei Wien Battloggstraße 54, 6780 Schruns Schloss-Straße 19, 5020 Salzburg Schillerplatz 2, 8280 Fürstenfeld Erzherzog-Johann-Str. 400, 8970 Schladming Schulgasse 261, 8811 Scheifling i look forward to hear from you!! regards
