A parameter in Java is a value that you can pass into a method in Java. It's a way to input data into methods. When you define a method, you can specify the parameters. Here are the steps to understand it:

1. **Method Declaration**: In Java, when you declare a method, you can list parameters that the method requires to perform its task. For example, in `public void showName(String name)`, `String name` is a parameter. This method requires a String type parameter named 'name'.

2. **Passing Parameters**: When you call a method, you need to provide those parameters. For example, `showName("John")`. Here, "John" is the argument value for the parameter 'name'.

3. **Using Parameters in Method**: Inside the method, you can use the parameter as a variable. For example:
```java
public void showName(String name) {
System.out.println("Name is: " + name);
}
```
Here, 'name' is used as a variable inside the method.

So, in summary, parameters in Java are variables that act as placeholders that represent the values to be input to a method when the method is called. You can think of them as the "input" to the method.
