Yes. The definition of function overloading is multiple methods with the same name, but different numbers of arguments and return types.
static int getArea(int height, int width) {
return height * width;
}
static double getArea(double height, double width) {
return height * width;
}

Why is multiple inheritance implemened through interfaces?
Interfaces have only methods declared and not defined. So that these various methods can be altered or customized or written according to the need. Hence Multiple inheritance is implemented through Interfaces.Interface is a progam which just declares various methods or functions, so that any user can write the contents of that method declaration.AnswerTrue Multiple Inheritance refers to the ability to inherit from multiple CLASSES. Thus, a true multiple inheritance language does not use interfaces. However, many single-inheritance languages provide most of the benefits of the multiple inheritance concept by using interfaces (Java, for example). The problem with true Multiple Inheritance is twofold:(a) at the compiler and runtime level, it is often difficult to determine which method is being referred to, as M.I. can lead to very convoluted (and sometimes conflicting) namespaces(b) there is no specific superclass, which can lead to problems with determining relationships between classesUsing a S.I. model with interfaces avoids these two problems.
Why do you need to write brackets after such command as getName in java?
The parentheses are used in methods to specify arguments. Some methods don't use arguments; but it would in fact be more confusing, not less, to omit the parentheses in this case - because the parentheses give some kind of consistency.The parentheses also help make it clear when something written after a dot is a field, and when it is a method. For this reason, in languages that allow you to either write or not write the parentheses for methods without arguments, I would always write them, for clarity and consistency.The parentheses are used in methods to specify arguments.

Define method overloading and write two method headers that together exhibit overloading?
Method overloading is when two or more methods have the same name, but the computer can differentiate between the methods by looking at the parameters. Example: public static void go(int x) public static void go(double x) If you pass an int, the first method would be called. If you pass a double, the second method would be called
What is need for function overloading in Java?
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.
