A common requirement is for a program to look for a given piece of data in an array by examining each position in the array in turn. This is known as a linear search. Write a program which reads and stores in an array 10 integers from the command line, and then prompts the user to enter a single integer from standard input. If the entered number occurs in the array, the program should print out the first index at which it occurs:

Write a program which reads and stores in an array 10 integers from the command line;;;;????????????what does this line mean ?? From my understanding

Are you having issues with getting input or with storing it in an array?

[mikesta]

set of arrays are to be input from user and not generated randomly.... and an input of arrays from user is to be input when running the file i.e. java Test 1 2 3 4 5 6 7 8 9

I understand the statement of the problem. What part of it are you having difficulty with? What do you have so far?

He seems to be having trouble taking in command-line arguments...

class MyClass
{
    public static void main(String[] args)
    {
        // See that "String[] args" up there? That's where command line arguments
        // go. To use it, all you've got to do is extract the values from that set of args.
        // You can treat the args String array just like any other String array!
