Avoid Premature Object Creation


This is a simple tip that proves useful in the long run. Consider the following example:
 
void someFunction() {
Date d= new Date(); // The Date object is created outside 
the scope where it is used.
If (…) {
	// The Date object is actually used here.
}
}

Define the objects in the scope that uses them. If the If() statement evaluates to “False”, the creation of the Object (and Garbage Collection) is wasted.
