How to write code that is not easy to overflow memory

Why did it run out of memory ？

as a result of ： constantly new object （ Strong reference objects are not JVM The recycling , Even if the memory overflows, it will not be recycled ）

How to write code that is not easy to overflow memory ？

void functionA(){
	// To use less new Object to create a strongly referenced object 
	for(){
		// Here you can create soft reference objects , If there is a memory overflow , Soft reference objects are also recycled 
		functionB();
	}
	
}

void functionB(){
	//functionB It is best to create weak reference objects in , such , When the scope is JVM When it's recycled , Weakly referenced objects are also recycled 
	
}

summary

1、for Loop call method , The object of the method is preferably a weakly referenced object (new weakreference)
2、 The object of the main method body , If possible , Is to use soft reference objects (new softreference)
