Having problems coding a char array to a string

Question

I'm trying to use a string constructor to convert the 2d char array into a string. Having problems finding the proper constructor. I attempted using various constructors but nothing seems to work.

Answer 1

What do you mean a 2d char array into a string?

If you have this: {{'a', 'b', 'c'}, {'d', 'e', 'f'}}

Do you want the result to be: "abcdef"?

Answer 2

You want to turn a 2d char array into a single string? Seems kind of strange. Do you want to just concatenate each row at the end of the last row?

Long story short, I don't think you will find a built in constructor to do that. You are probably going to have to write something to do that conversion on your own.

EDIT:
Based on your comments it looks like you are using the wrong data structure when you originally read the file. Here is a code snippet to read an entire file into a string so you don't have to do any conversion later.

  StreamReader MyStreamReader = new StreamReader(@"c:\Projects\Testing.txt");
  string fileContents= MyStreamReader.ReadToEnd();
  MyStreamReader.Close();

Answer 3

char chars[][]= {{'a', 'b', 'c'}, {'d', 'e', 'f'}};

        StringBuilder sb = new StringBuilder();

     for(int i = 0; i<2 ;i++){

         for(int j =0; j<3; j++){


             sb.append(chars[i][j]);

         }

     }


        System.out.print(sb.toString());

this is one of my option to do .. nevertheless.. there might be a good code!! look for it!!!

Answer 4

This will give you a list of String's

    char[][] arr={{'a', 'b', 'c'}, {'d', 'e', 'f'}};
    List<String> list=new ArrayList<String>();
    for(char[] ar:arr)
    {
        list.add(new String(ar));
    }

If you want the 2d char array as a single string:

    StringBuilder b=new StringBuilder();//use string builder instead of list
    for(char[] ar:arr)
    {
        b.append(new String(ar));
    }

If you simply want to print the char 2d array:

Arrays.deepToString(arr));
