Yes, you can modify a method by adding a caching mechanism to store the returned value after the first access. This can be done by adding a class-level variable that holds the cached value, and modifying the method to check if the cached value exists before executing the method. Here is an example:
public class MyClass {
private int cachedValue;
public int calculateValue() {
if (cachedValue != 0) {
return cachedValue;
}
// your original calculation code here:
int result = ...;
cachedValue = result;
return result;
}
}
In this example, the calculateValue()
method checks if cachedValue
has been set before, and if it has, it returns the value directly without executing any calculation code. If cachedValue
has not been set, it executes the original calculation code, stores the result in cachedValue
, and returns it. This way, subsequent calls to calculateValue()
will return the cached value, which can save time and resources.
