Since the question is in the Java category: in Java, the method is called toString(). This method will automatically be invoked if you implicitly convert an object to String type, for example:
"The answer is: " + myObject
In this example, the String concatenation (the plus sign) forces the object, myObject, to type String - to do this, the object's toString() method will be called.
"[Substr] returns a string object with its contents initialized to a substring of the current object."
The toUpperCase() method returns the uppercase equivalent of a string.
It is called a local variable since it only exists inside the method.
The Scope of a variable defines the areas of a program where this variable would be visible and can be used. For ex: a. Method variables - are visible only inside the method where they are declared and hence their scope is only the method b. Class variables - are visible inside the class and can be used by any method inside the class and hence their scope is the whole class.

what are the variable
The toUpperCase() method returns the uppercase equivalent of a string.
It is called a local variable since it only exists inside the method.
a method is a variable
The Scope of a variable defines the areas of a program where this variable would be visible and can be used. For ex: a. Method variables - are visible only inside the method where they are declared and hence their scope is only the method b. Class variables - are visible inside the class and can be used by any method inside the class and hence their scope is the whole class.

The independent variable
I guess an object in a method would be any object variable, used within a method. An object variable of course is a variable that is declared as a variable of a certain class type.

High and low method is the method for separating fixed cost and variable cost from mixed cost.
