Difference Between Argument And Parameter In Java
In Java, a parameter is a variable that is listed in a method's declaration. It is used to pass information to a method when it is called. An argument, on the other hand, is the actual value that is passed to the method when it is called. Essentially, a parameter is a placeholder for the value that will be passed as an argument when the method is invoked. To clarify, parameters are defined when a method is created, while arguments are provided when the method is called.

1 - In Java, one key difference between arguments and parameters is that parameters are used to define the data that a method expects to receive, while arguments are the actual values that are passed to the method when it is called.
2) Parameters act as placeholders in the method signature, indicating what type of data the method expects to receive, whereas arguments are the specific values that are provided when the method is invoked.
3) Parameters are declared in the method signature within parentheses, listing the data type and name of the parameter, while arguments are provided when the method is called inside the parentheses.
4) Parameters are used to pass information into a method, while arguments are the values passed to the method during the function call.
5) Parameters are local variables that are initialized with the values of the arguments passed to the method.
6) When defining a method, you specify the parameters in the method signature, which serve as placeholders for the data that will be passed to the method.
7) Arguments are passed to a method when it is called, providing the actual data that the method will work with.
8) Parameters are part of the method declaration, while arguments are part of the method invocation.
9) Understanding the difference between arguments and parameters is crucial for writing effective and functional Java code.
10) Providing a training program that covers the fundamentals of using arguments and parameters in Java will help students gain a solid understanding of how to work with methods and pass data effectively.
