Any function or method in Java that is coded by the programmer is called a user defined method in Java. The JAVA API (Application Programming Interface) has a set of predefined classes & methods that are for our usage. Whatever methods we create apart from these are termed as user defined methods. In java we not use the term functions. We call them "Methods"

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.

Function prototyping isn't necessary in Java, but what function prototyping means is simply establishing the "signature" of the "function" (functions are referred to as 'methods' in Java) before the method is defined. The signature includes the visibility of the function (public, private, protected), the return type, the method name, the list of arguments the method takes, and any throws, extends, or implements clauses.

Operator overloading is possible in java or not?

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


Rules for function overloading?

It's a way by which you use define the same function for different input types. For example, think about the the operator "+" which in java works for adding integers, floating point numbers and even string concatenation. The way such functionality is achieved is by overloading.


How operator overloading differ from function overloading?

Function overloading is multiple definition with different signatures(the parameters should be different) for the same function. The parameter list have to be different in each definition. The compiler will not accept if the return type alone is changed. Operator overloading is defining a function for a particular operator. The operator loading function can not be overloaded through function overloading.

What is function overloading in c language of computer?

There is no such thing as function overloading in C; that is a feature of C++. Function overloading allows us to provide two or more implementations of the same function. Typically, we use function overloading so that the same function can cater for different types. For instance, we might provide one implementation that is optimised to handle an integer argument while another is optimised to handle a real argument. We can also use function overloading to provide a common implementation of a function which can then be invoked by overloads that handle the low-level type conversions.

What is the function of this in java?

this in java is a keyword that refers to the current object of the class. It is also used in constructor overloading when you want to invoke one constructor from another within the same class.


Why java not support oprator overloading?

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

No. Operator and/or function overloading is only a C++ thing.

Why do you use of operator overloading in c?

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++ ...


Why java not support operator overloading?

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.
