Question

what is output? java myprogram file1.txt public class myprogram{ public static void main(string[] args){ system.out.println(args[0]); } } group of answer choices error: array index out of bounds java myprogram file1.txt

Answer 1

The output of this Java application is determined by whether it is executed with command-line parameters and what arguments are supplied.

If the program is executed with the command "java MyProgram file1.txt," the result will be "file1.txt," which is the value of the program's first command-line input. This is because the program displays the first member of the "args" array, which is the program's first command-line argument.

If the program is executed without any command-line arguments, such as "java My Program," it will raise an Array Index Out Of Bounds Exception because the "args" array contains no items.This is because the program thinks that the "args" array contains at least one element and attempts to reach the first element at position 0, which does not exist in this instance.
