the variable exists only within a method◦Object scope - the variable can be accessed from anymethod belonging to an object.◦Class scope - the variable can be accessed by all instancesof a class.Department of Computer Science — University of San Francisco25-4: Parameters•Parameters are the variables passed into a method.•We can talk about:◦Formal parameters - these are the variables named in themethod definition.◦Actual parameters - these are the variables in the methodinvocation.Department of Computer Science — University of San Francisco – p. 4/??25-5: Example/**This is a method definition*/public double depositFunds(double amt) {balance = balance + amt;return balance;}...bankacct b = new bankacct();paycheck = 100.0/*this is a method invocation*/b.depositFunds(paycheck);Department of Computer Science — University of San Francisco – p. 5/??25-6: Method signature•Specification of all data types coming in and out of a method.◦Type and order of input parameters◦Type of return variable•A method signature allows the compiler to uniquely identify amethod.Department of Computer Science — University of San Francisco25-7: Example•Consider the following method declaration:•double calculate(double a1, double a2, double a3);•Which of the following are valid calls to this method?◦calculate(3, 52.0, -5.1);◦double y = calculate(0, 1.1, 2.2);◦calculate(1.1, 2.3);◦calculate(“Hello”, 4.4, 2);◦calculate();◦calculate(3.3);Department of Computer Science — University of San Francisco – p. 7/??25-8: Objects•An object is a type of
