Answer:
The answer is a. int count =args.length
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.
Answer:
The answer is "Virtual machine
".
Explanation:
The VM stands for Virtual machine, it is a portable device, that operates on the actual hardware framework as a virtual software to its Processor like, ram, network access, and data. It is a project called hypervisor splits the assets of the system from both the hardware and distributes the resources directly.
- It runs the program as if the host's internal memory is a true physical device, but is isolated from the host's underlying hardware.
- It can run an operating system on your desktop in an app window, that functions as a full, separate device.
<span>I agree with one small part, but disagree with the rest. A computer as hardware is a machine that can do what software tells it to. If the software is stored directly on the hardware and relatively immutable, they cal it firmware. If it is easily changed and updated they just call it software. If you remove that completely, yes, the hardware is difficult to use for more than door stops and paper weights. However, you do not need hardware to use software. Software is a concept. Software development can be abstracted from the hardware. Algorithmic thinking can be used for theory or applied to other topics that do not use computers. </span>

Answer:
Explanation:
If a function is not working, there are three possibilities to consider: There is something wrong with the arguments the function is getting; a precondition is violated. There is something wrong with the function; a postcondition is violated. There is something wrong with the return value or the way it is being used.
a. precondition
A precondition is a prerequisite. It's the thing that has to happen before something else happens. ... When it's a verb, precondition means to prepare something (or someone).
b)a postcondition
A postcondition is the states the system can be in after the use case has ended. Consider the following: The states described by pre- or postconditions should be states that the user can observe. "The user has logged on to the system" or "The user has opened the document" are examples of observable states.
c)As in any programming language, "return value" means the value that is returned by any sub-routine. All subroutines need not return values, sometimes return void (means nothing). Return values often indicate something about the completion of the task or result of an operation.
