Definition - What does Overloading mean? Overloading refers to the ability to use a single identifier to define multiple methods of a class that differ in their input and output parameters. Overloaded methods are generally used when they conceptually execute the same task but with a slightly different set of parameters.
Operator overloading is the ability to tell the compiler how to perform a certain operation when its corresponding operator is used on one or more variables. For example, the compiler acts differently with regards to the subtraction operator-depending on how the operator is being used. When it is placed on the left of a numeric value such as -48, the compiler considers the number a negative value.
