Question

In the body of the main method: public static void main(String[] args) What is the value of args[1] if the user runs the following via the command line? java MyProgram hello 1 world 2

a. "java"
b. "MyProgram"
c. "hello"
d. 1
e. "1"
f. "world"
g. 2
h. "2"

Answer 1

The value of args[1] when running the Java command java MyProgram hello 1 world 2 would be "1" as command line arguments start at index 0, and "hello" would be args[0].

Step-by-step explanation:

When a Java program is run from the command line, the main method's args array contains the command line arguments passed to the program. The first argument is at index 0, the second at index 1, and so on. In the given command java MyProgram hello 1 world 2, the elements of the args array would be as follows:

• args[0] = "hello"
• args[1] = "1"
• args[2] = "world"
• args[3] = "2"

Therefore, if the user runs the command above, the value of args[1] would be "1" (option e).
