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.

Operator overloading is not possible in Java.


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


really there is no difference between constructor overloading and metho overloading



By implementing polymorphism we need to use overloading and overriding Technics in program..


Java does not support operator overloading because Sun deliberately omitted it, citing simplicity as the reason for omission.

Java does not support user defined operator overloading.The operator '+' is overloaded in Java and can be used for adding both numbers and Strings.


Overloading is very useful in Java. For instance, methods can be overload as long as the type or number of parameters (arguments) differ for each version of the method. This comes in handy when, for instance, you need to perform a complex mathematical operation, but sometimes need to do it with two numbers and sometimes three, etc.


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


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


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


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.

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



Method overloading is a technique in Java where you can have multiple methods in a class with the same name. These methods will have a different signature. Ex: public int add(int a, int b){} public float add(float a, float b){} The above two methods have the same name but a different signature. This is method overloading.


False. Two methods can have the same name in Java. It is called Method Overloading.


You cannot explicitly overload an operator in Java but by default the + symbol is overloaded. You can use it to add numeric values as well as concatenate strings.


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.



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.


Java supports method overloading. Several methods in a class (or extension), can use the same method name with different parameters and same result type.
