what is the difference between type equivalence and type compatibility?
604836
Equivalence is a tighter relationship. Objects and contexts can be equivalent only when their types are same. Type Compatibility: Type Compatibility determines where an objects of a certain type can be used, that is, it tells what kind of data can be held in the object depending on the compatibility of its type.

First, dynamically-typed languages perform type checking at runtime, while statically typed languages perform type checking at compile time. ... If a script written in a statically-typed language (such as Java) contains errors, it will fail to compile until the errors have been fixed.

Key Differences Between int and long The basic difference between the type int and long is of their width where int is 32 bit, and long is 64 bits. The types int and long when counted in bytes instead of bits the type int is 4 bytes and the type long is just twice if type int i.e. 8 bytes.

There are two main differences between dynamic typing and static typing that you should be aware of when writing transformation scripts. First, dynamically-typed languages perform type checking at runtime, while statically typed languages perform type checking at compile time.

Comparator interface belongs to java. util package while comparable belongs to java. lang package. Comparator interface sort collection using two objects provided to it, whereas comparable interface compares" this" refers to the one objects provided to it.

In Compile time Polymorphism, the call is resolved by the compiler. In Run time Polymorphism, the call is not resolved by the compiler. It is also known as Static binding, Early binding and overloading as well. It is also known as Dynamic binding, Late binding and overriding as well.

It is not type safe i.e. Compiler doesn't have any information about the type of variable. The object type can be passed as a method argument and method also can return object type. Var type cannot be passed as a method argument and method cannot return object type. Var type work in the scope where it defined.

Starting with C# 7.0, the is and switch statements support pattern matching. The is keyword supports the following patterns: Type pattern, which tests whether an expression can be converted to a specified type and, if it can be, casts it to a variable of that type.

Static polymorphism : Same method name is overloaded with different type or number of parameters in same class (different signature). Targeted method call is resolved at compile time. Dynamic polymorphism: Same method is overridden with same signature in different classes.

The 2 main differences are that: equals will take any Object as a parameter, but compareTo will only take Strings. equals only tells you whether they're equal or not, but compareTo gives information on how the Strings compare lexicographically.

Polymorphism is the process to define more than one body for functions/methods with same name. Overloading IS a type of polymorphism, where the signature part must be different. Overriding is another, that is used in case of inheritance where signature part is also same.

Interface: Interface Programs are similar to Conversion program. There is no difference in Coding Perspective. Conversion is one time process where as Interface is on-going Process. ... Inbound Interface: Transferring the data from the legacy system into the Oracle apps base tables.

Explanation: Since,conversion of data type is implicit type as 'int' is a subset of 'longtype' hence no need to explicitly convert data from one type to another. Compiler will automatically do conversion.

The difference to List now is that List is untyped and therefore no type checks at all are performed, which ultimately leads to certain warnings and can lead to weird runtime behavior. While Java knows that List<Object> is a list that might contain anything, it doesn't know that about a List .

Some common data types in TypeScript are: number , string , boolean , enum , void , null , undefined , any , never , Array and tuple . Let's learn more about these basic data types of TypeScript, which you will always need to use.

IEqualityComparer<T> is a generic interface defined in the . NET framework version 2.0 and used in many standard classes, including several LINQ operators. The interface can be implemented to allow customised comparison of values and objects.
