Question

I get a compilation error while trying to compile, “not a statement”, and the code is:

(checkDatabaseExist())?connectToDB() : buildDB();

when the functions are:

private boolean checkDatabaseExist() {...}
private void connectToDB(){...}
private void buildDB(){...}

any ideas?

Yes, you can’t use the conditional operator like that. It’s intended to compute one expression or another as a result. It’s not intended to be a way of choosing one statement to execute or another.

Just use:

if (checkDatabaseExist()) {
    connectToDB();
} else {
    buildDB();
}
