Java vs C++

Question

Please explain main 5 difference between java and c++.

Answer 1

@Kris Clark
C++ not C#

C++ doesn't use garbage collection
C++ is WAY faster
C++ doesn't use virtual machines
C++ doesn't try to make you install ask.com toolbar
C++ is more low level

Answer 2

@Kuldeep
I don't know any difference between them, but I want to ask this question:-

why do you need only 5 differences...
there may be more than that......

Answer 3

1 extra difference to the ones listed above is Java is write once, run anywhere. Any Java program you make will run on any system with the JVM installed.

C++ must be compiled for each architecture that you wish to run the program on.

Answer 4

1. The mechanism of work with dynamic data and the garbage collectors
In Java and C # are strong and weak references to the objects. Both languages support the finalizer method. Due to the uncertainty of the moment of the object removal, finalizers can not be used to release the system resources occupied by the object. This compels to create additional methods for the object “cleaning” and causes them explicitly.

2. Encapsulation
In Java, the “protected” modifier in the description, besides the access from descendants classes, permits the access from all the classes that are in the same packet as the class owner.

In C #, for the objects which should be visible in the range of assembly (the approximate analog of Java package) was introduced the separate “internal” modifier (“default” analog in Java), while “protected” retains its original meaning taken from C ++, the access only from descendants classes. You are able to combine “internal” and “protected”.

3. Inner classes
Both languages allow determining the class inside the class.
In Java, inner classes are used to emulate the circuits. C # has circuits and lambdas.

4. Methods

In C # there is an obvious realization of the interface methods that allows any class implementing the interface methods separately from its own methods or to give different implementations of the same name methods belonging to the two different interfaces.

In Java 8 the default operator has appeared which allows determining the implementation of the “default” interface methods. Thus, the interface class gets rid of the obligation to realize the default methods, but can override them.

5. Types of data
Java and C# can refer to the several types.
