Join Todd Perkins for an in-depth discussion in this video Populate a table from an external file, part of Learning Java Applications (2016).
- [Voiceover] So we've looked at populating a table…using a two dimensional array,…but what if we wanted to grab that data…from an external file?…So I'm here in Layout.java, and I've created…an additional text file and added it to my project.…So there it is, data.txt, it's a plain text file.…I've just added five rows and five columns.…Now if you're following along without the exercise files,…it might be easier to make three rows and three columns.…One, two, three, four, five, six, seven, eight, nine.…I made them two digit numbers so they would all be aligned…so it's easy to tell how many rows and columns that I have.…
But for the purpose of this exercise,…we want an equal amount of rows and columns.…Now you don't have to always have an equal amount…of rows and columns, but just for what we're doing right now…and how we're writing this code,…you're going to need equal rows and columns.…So back to Layout.java, and let's look…at what code is already here.…So we are reading from the allData array…for the row count and the column count…
