It means that when a variable is pass-by-reference,the unique identifier of the object is sent to the method.Any changes to the parameter’s instance members will result in that change being made to the original value. 3. Parameter Passing in Java The fundamental concepts in any programming ...
Most fundamental of these obstacles is the limited range of parameter passing modes offered by the JVM. We discuss possible ways of using the JVM to provide parameter passing modes with alternative semantics, and explore one particular architecture in practice. The interaction between these mechanisms...

Before the method executes, the argument gets assigned to the parameter. In this example, the argument"Don't make me say this twice!"gets assigned to the parameters. This process is calledparameter passingbecause the value gets passed from outside the method to the inside. An argument can be...
