Pressumably, the designers of Java thought this would lead to confusing code.

Operator overloading refers to redefining what the mathematical operators (+-*/) do when applied to different objects. Java does not support operator overloading.

Operator overloading is not possible in Java.

Java does not support opperator overloading, so the answer to your question is: none.

Java does not support object overriding. It does support operator overloading by means of the "+" symbol which is used for both numeric addition as well as string concatenation.

really there is no difference between constructor overloading and metho overloading

Java does not support operator overloading. Operator overloading is the scenario where you overload a particular operator to do something that it is not designed to do. Ex: if you make the operator "*" do addition or the operator "-" do multiplication, imagine the chaos that would ensue in your program. So the java designers blocked this feature of operator overloading.

Operator overloading was a feature of C++ that the Java language designers thought was too complicated and not useful enough to include.

method overloading is the primary way polymorphism is implemented in JavaOverloading methodsoverloaded methods: appear in the same class or a subclasshave the same name but,have different parameter lists, and,can have different return types

Difference between Java and C++ is that Java does not support pointers. Pointers are inherently insecure and troublesome. Since pointers do not exist in Java, neither does the -> operator. Some other C++ features are not found in Java. • Java does not include structures or unions because the class encompasses these other forms. It is redundant to include them. • Java does not support operator overloading. • Java does not include a pre-processor or support the pre-processor directives. • Java does not perform any automatic type conversions that result in a loss of precision. • All the code in a Java program is encapsulated within one or more classes. Therefore, Java does not have global variables or global functions. • Java does not support multiple inheritances. • Java does not support destructors, but rather, add the finalize() function. • Java does not have the delete operator. • The << and >> are not overloaded for I/O operations. • Java does not support templates.

If you want to change the behavior of a method that exists in a super class, overloading is the only way you can alter the behavior.

Overloading, Overriding, Polymorphism, Information Hiding, Inheritance all these are CONCEPTS of C++ and Java. An Object Oriented Language and not of C language. Thats why Bjarne Stroustrup came up with C++ ...

Function overloading is a C++ thing, not a C thing.

Because it would create unnecessary complications and people might end up using operators to do things that they arent supposed to do.

how many constructer can be defined in class in overloading of java programming

Java does not support multiple inheritance.......

Maybe because Sun said so. We have to bear with so many other idiosyncrasies too. But I guess that comes with every language. There were two major reasons why operator overloading wasn't allowed in Java: "cleanliness" and compiler complexity. The main reason was the first, a personal preference choice made by Java's creator, James Gosling. Operator overloading, while useful, can be exceedingly confusing, much more so than method overloading. Given the human tendency to assign specific meanings to single symbols, it is hard to get programmers to wrap their heads around multiple meanings for operators. What this means is that there is a marked increase in programming errors when a language supports operator overloading. Since practically the same benefit can be obtained via methods, the Java designers decided that the increased programmer mistake rate was not worth supporting operator overloading. From a Java compiler (e.g. javac) design standpoint, supporting operator overloading is considerably more difficult than method overloading, requiring a more complex compiler.

No it does not support Java

No. Java does not support copy constructor
