what is parameter in java

In Java, a parameter is a variable used to define a particular value during a function definition. Parameters are specified after the method name, inside the parentheses, and act as variables inside the method. You can add as many parameters as you want, just separate them with a comma. Arguments, on the other hand, are the actual values that are passed in when the method is invoked. When you invoke a method, the arguments used must match the parameters in number, order, and type. The values passed as arguments replace the variables used during the function definition and the function is then executed with these values.
