Java init method
- by Johan Sjöberg
What's a good way to make sure an init method is invoked in java? The alternatives I see are
Don't test it, let the method fail by itself, likely by a NullPointerException
Test if method was initialized or throw
public void foo() {
if (!inited) {
throw new IllegalArgumentException("not initalized");
}
...
}
Delagate
public void foo() {
if (!inited) {
throw new IllegalArgumentException("not initalized");
}
fooInternal();
}
private void fooInternal(){ ... };
Always init, and make init a noop otherwise
public void foo() {
init();
...
}
public void init() {
if(!inited) {
...
}
}
Silently init
public void foo() {
if (!inited) {
init();
}
...
}
Most of these approaches are very verbose and decreases overall readability.
