Explanation:

Which code fragment would correctly identify the number of arguments passed via the command line to a Java application, excluding the name of the class that is being invoked?

a. int count = args. length;

b. int count=0; while (! (args[count]. equals (""))) count + +;

c. int count = args. length - 1;

d. int count = 0; while (args[count]! = null) count + +;

The answer is a. int count = args. length

args is a string array object, which contains set of all arguments. You can find the number of argument by using args. length.
