What is the difference between Java  and C++

There are many differences and similarities between the C++ programming language and java. A list of top differences between C++ and Java are given below

1.Pointers

• Java: Java does not support pointers, templates, pointer overloading, unions, etc. 
• C++: C++ does support pointers, structures, unions, templates, operator overloading, or pointers arithmetic.

2. Support Destructors

• Java: Java doesn’t support destructors; it has an automatic garbage collection system.
• C++: It supports destructors; it gets invoked when an object is destroyed.

3. Conditional Compilation and Inclusion

• Java: It doesn’t support conditional compilation and inclusion.
• C++: These are the major features of C++.

4. Thread Support

• Java: It has built-in supports threads in Java. There is a thread class in Java, inherit to create a new thread override the run method.
• C++: C++ doesn't have built-in support for threads. It relies on third-party libraries for thread support

 5. Default Arguments

• Java: Java does not support default arguments. There is no (::) in Java. The strategy definitions should dependably happen inside a class, so there is no requirement for scope determination there either.
• C++: C++ supports default arguments. C++ has scope resolution (::), which utilize and characterize a strategy outside a class to get to a worldwide variable inside from the degree where a neighborhood variable additionally exists with a similar name.

6. Goto Statement

• Java: Java doesn't support the goto statement
• C++: C++ supports the goto statement.

7. Multiple Inheritances

• Java: JJava doesn't support multiple inheritances through class. It can be achieved by interfaces in java.
• C++: C++ supports different inheritance. The keyword virtual utilizes to determine ambiguities amid various legacy if there is any.

8. Exception Handling

• Java:  Exception handling is different because there are no destructors. In Java,  try/catch must define if the function declares that it may throw an exception.
• C++: While in C++, you may exclude the attempt/get regardless of whether the capacity throws an exemption.

9. Method Overloading and Operator Overloading

• Java: Java has method overloading but no operator overloading. The classString does use the and++= operators to concatenate strings and expressionsString use automatic type conversion, but that’s a special built-in case.
•    C++: C++ supports both technique over-loading and administrator over-loading.

10. Call by Value and Call by reference

• java: Java supports call by value only. There is no call by reference in java
• C++: C++ supports both calls by value and call by reference
