Question
Indicate when each of the following bindings takes place in Java (language design time, language implementation time, compile time, link time, load time, or run time). If more than one time is possible, choose the latest possible time. (a) Binding of the float type to a specific number of bytes (i.e., the decision to use a specific number of bytes to store a float value) (b) Binding of the+ operator to a particular operation (c) Binding of a named array variable to a specific element type (d) Binding of a character literal to a numeric code (e) Binding of a method call to a particular methodExplanation / Answer
Solution:
There is no compile-time memory allocation.
The question conflates compile-time with static binding and run-time with dynamic binding.
1) Static binding in Java occurs during Compile time while Dynamic binding occurs during Runtime.
2) private, final and static methods and variables use static binding and bonded by compiler while virtual methods are bonded during runtime based upon runtime object.
3) The static binding uses Type(Class in Java) information for binding while Dynamic binding uses Object to resolve binding.
4) Overloaded methods are bonded using static binding while overridden methods are bonded using dynamic binding at runtime.
a)
The space taken in memory is defined in the syntax of the language so, Language design time
b)
bind operator symbols to operations: - Language design time
c)
Compile time
d)
run time
e)
compile time
