Koray Tugay Maybe you should remove that. Reading in char by char will return a newline character for each new line. Scanner assumes that you just want the line's contents and returns a null-terminated String instead. The result is that if you want one gigantic String as alluded to by the initial length of you need to re-add those back between each line's character data.
Java String concatenation gets rid of the null-termination between appended strings In short, this is how you need to do it to get identical results — darkpbj. Try your program with just one single line and you'd understand.
Because that's what br. You can't just ignore newline characters. The OP was unclear on his intentions, and honestly it's important.
Readline would do a fantastic job of reading that line by line, but if the intention were to handle an entire HTML document in a single String, you would need to reinsert those characters. Your answer is incorrect based on the original post in assuming the OP's use although that seems like what he is going for here — darkpbj. Show 3 more comments.

I am trying to fill a char[][] array from a text file and I cannot seem to figure out how to do it. I've tried to use. If you can give any insight on how to make this work that would be awesome!
The basic problem is that you are trying to assign a character array to something was meant to hold a character. You might think of char[] type as storing the location in memory where characters are recorded, and a char type as the character itself.
When you call toCharArray on a String , the return type is char[]. It looks like you expect this array to have a single character, like the A, B, C, or D of a multiple-choice test.
You could get the first and only? It's simpler to use the getCharAt method on the String directly. Stack Overflow for Teams — Collaborate and share knowledge with a private group. Related Articles. Table of Contents.
