I am separating a word in Java whose separator is a -, my problem comes in that sometimes it does not have - to separate and therefore it gives me an error, as I could previously detect that the separator does not exist. An example to be understood: That is, it works correctly
String palabra="hola-adios";
But if I pass through the Split a string without a separator like the following, there is an exception:
String palabra2="hola";
Use the contains() method of the String class that lets you know if a string contains another within.
if (palabla.contains("-")) {
// Aplicas el split
}
Strings in java have a method called contains, which returns a Boolean value if the string contains another ...
You can use it this way:
if (palabra.contains("-")) {
String[] identificador = palabra.split("-");
// Lo que deses hacer con eso
}
