Here is a function which take a long String and return a string divided in paragraph.
The problem is that k is empty. Why split()
function doesn't work?
private String ConvertSentenceToParaGraph(String sen) {
String nS = "";
String k[] = sen.split(".");
for (int i = 0; i < k.length - 1; i++) {
nS = nS + k[i] + ".";
Double ran = Math.floor((Math.random() * 2) + 4);
if (i > 0 && i % ran == 0) {
nS = nS + "\n\n";
}
}
return nS;
}
String.split(String regex)
takes a regular expression. A dot .
means 'every character'. You must escape it \\\\.
if you want to split on the dot character.
split
expects a regular expression, and "."
is a regular expression for "any character". If you want to split on each .
character, you need to escape it:
String k[] = sen.split("\\.");
split()
method takes a regex. And .
is a meta-character, which matches any character except newline. You need to escape it. Use:
String k[] = sen.split("\\.");
Change:
sen.split(".");
To:
sen.split("\\.");
You need to escape the dot, if you want to split on a dot:
String k[] = sen.split("\\.");
A .
splits on the regex .
, which means any character.
