I have a String like the following:
String foo = "soy un texto"
When applying the following function:
String [] bar = foo. split(" ");
He separates it into three texts:
"soy", "un" y "texto"
However, I want to keep the spaces like the following example:
"soy", " un" y " texto"
How can I do that?
With the clarified specifications the regex that you can use in split is:
String foo = "Soy un texto";
String[] bar = foo.split("(?=\s)");
for (String foobar : bar ){
System.out.println(String.format("<%s>", foobar));
}
(?=X) makes you a match of places followed by a space, without consuming characters.
Result:
<Soy>
< un>
< texto>
We can add an element that will serve as an identifier to make split for example:
String foo = "soy un texto";
foo = foo.replace(" ", "☺ ");//remplazamos por un caracter que no tenga la cadena
//y dejamos el espacio ^ en blanco
String [] bar = foo.split("☺");//y despues usamos el caracter
This gives
"soy"
" un"
" texto"
If we want the space on the right we change our replace for .replace(" ", " -")
What would you give:
"soy "
"un "
"texto"
you can add it yourself after doing the split
for(int i = 0;i < bar.length; i++) {
if(i != 0) { //para que no se lo agregue al primer split
bar[i] = " " + bar[i];
}
}
