A method is a unit of code that you call in a Java program. A method can support arguments and usually returns a value. To create a method in Java, follow these four steps.

1. Open your text editor and create a new file. Type in the following Java statements:

The method you have coded is named computeAreaOfRectangle. It accepts two integer arguments and returns an integer, the product of the two arguments.

2. Save your file as CreateAMethodInJava.java.
3. Open a command prompt and navigate to the directory containing your new Java program. Then type in the command to compile your program and hit Enter.
4. You can now test your Java program. Type in the command to run the Java runtime launcher and hit Enter. Observe the results of calling your method.
