How to get 2d array from multiple line String?

Question

Sorry for my noob question.. I have String with multpile lines

String is like this:

1   kave    Topli napitci   7
2   sokovi  Sokovi  12
3   pive    Pive    14
4   žestice     Domaæa Žestoka P    16
7   ostalo  Hrana   50
8   vino    Vino    33
9   6   Strana Žestoka P    34

What i want to get 2d array for every word.

I do something like this:

String[] lines =string.split(System.lineSeparator());

String[] parts =  string[0].split("\t");
String[] parts1 = string[1].split("\t");
String[] parts2 = string[2].split("\t"); ....

Please help how to do this in 2d array.

@NikolaBozic is this string in a file? Or is it assigned to a variable in your program? — ClarksonDev

List<String[]> lines = Arrays.stream(string.split(System.lineSeparator())).map(line -> line.split("\t")).collect(Collectors.toList());
lines.toArray(new String[lines.size()][]);

I think it would be better to assign the values directly to the array (but use ArrayList) while parsing from the file with something like this:

ArrayList<String[]> array = new ArrayList<String[]>;

while (file.hasNextLine()) {
   String str = file.nextLine();
   String[] strArr = str.split("\t");
   array.add(strArr);
}

This should give you an ArrayList filled with String Arrays that are split at the "\t" delimeter.

Yeah but this String is not complete file, the complete file has many more lines, this string is cut from wholw file.
