Refactoring if/else logic
- by David
I have a java class with a thousand line method of if/else logic like this:
if (userType == "admin") {
if (age > 12) {
if (location == "USA") {
// do stuff
} else if (location == "Mexico") {
// do something slightly different than the US case
}
} else if (age < 12 && age > 4) {
if (location == "USA") {
// do something slightly different than the age > 12 US case
} else if (location == "Mexico") {
// do something slightly different
}
}
} else if (userType == "student") {
if (age > 12) {
if (location == "USA") {
// do stuff
} else if (location == "Mexico") {
// do something slightly different than the US case
}
} else if (age < 12 && age > 4) {
if (location == "USA") {
// do something slightly different than the age > 12 US case
} else if (location == "Mexico") {
// do something slightly different
}
}
How should I refactor this into something more managable?
