how many times a word appears into a txt file
- by m4g4bu
I've a problem when i tried to count how many time a word appears into a txt file.
1/ I create a textfield ( txta )
2/ I create a button to apply the action ( btn )
3/ I create a textarea ( area ) that is the place where the content of the file is displayed
When I select the file, the content of the file is displayed on area, then I enter the word in txta to search and then I clicked the btn but the code is not working
public int contarPalabras(String chain, String word) {
// Recibe un string y una palabra y devuelve la cantidad de veces que encontró esa palabra en el string.
// Si no encuentra la letra devuelve (-1).
int cant = 0;
int intIndex = chain.indexOf(word);
if(intIndex == - 1){
cant = -1;
}else{
cant = intIndex;
}
return cant;
}
