Java - Methods and Code Reusability

Apublic void area(double width; double height)

Bpublic double area(width, height)

Cpublic double area(int width, int height)

Dpublic double area(double width, double height)

Step-by-Step Solution

Solution:

Step 1: Identify correct parameter types and syntax
The method should accept two double parameters named width and height, separated by commas.
Step 2: Evaluate each option
public double area(double width, double height) correctly declares two double parameters with names and commas; public double area(width, height) misses types; public double area(int width, int height) uses int instead of double; public void area(double width; double height) uses semicolon instead of comma and void return type.
Final Answer:
public double area(double width, double height) -> Option D
Quick Check:
Parameters need type, name, comma-separated [OK]

Quick Trick: Use type and name with commas for parameters [OK]

Common Mistakes:

Omitting parameter types
Using wrong separators like semicolons
Using wrong data types for precision
