PING is what you need to use . Ping 127.0.0.1
Input I would have thought.If you are refering to the big readers of the 80-column punched card then they are Input devices. But many of these devices were made so that they could also be used for output - ie for punching cards - these are both Input and Output devices.A card reader is an INPUT (not imput) device.Whenever you are trying to categorize a device as Input or Output, think of how it looks from the computer.If the computer is transmitting data to it, it is an Output device.If the computer is receiving data from it, it is an Input device.

I/O Redirection is used when you don't want the output to go to the standard output location, e.g., the screen. It can be very helpful in capturing information to be used in a later process. For example, if the command 'ls' is used the output goes to the screen. But if the command 'ls > ls.out' is used, then the ls command output will be redirected to a file called ls.out, which can be examined, edited, or used in a later process.

The correct command is System.out.println - note the uppercase "S"! Java is case-sensitive! This command is used to send data to the standard output, by default the screen. It can be used to quickly test some program. For example, you might include the following line in your main() method: System.out.println("Hello!");
The video card, or the motherboards onboard video output.
ping
That's the command used to output text to the console. For example: System.out.println("Hello!");
cat input1 input2 ... > output
Only one of the redirection operators will do this - the vertical bar or "pipe" symbol (|). It takes the standard output of one command and uses it as input to the next command in sequence.
You aren't specific in the test card you are asking about, but perhaps you are referring to The Rorscach test, which is also called the inkblot test. This test is used in psychiatry to help determine a person's mental state.
The javap command is used to disassemble one or more class files. Its output depends on the options used. If no options are used, javap prints out the package, protected, and public fields and methods of the classes passed to it. javap prints its output to stdout. For example: javap java.lang.String dumps all the methods for the String class.
