To overload a method in java, you only needs to write a method with the same name of other in your class but with diferente kind or number of parameters. For example:
class MyClass{
void printNumber(int x){
System.out.println(x);
}
void printNumber(int x, int y){
System.out.println(x+y);
}
}
the type of the value that your method return could change if you want.
While programming in c++ ,we need to use the same function name for many operations,So we need to overload function.
Yes.
Java does not support opperator overloading, so the answer to your question is: none.
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"
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.
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.

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.

Pressumably, the designers of Java thought this would lead to confusing code.
Defining several functions with the same name with unique list of parameters is called as function overloading.

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