how to take a series of string from command line?

[yuvraj kotegar]

Hi i know to take a series of string from command line??


i know to take it with args[0],args[1] but how to take it has a whole??

i mean if i enter "I AM LEARNING JAVA" in the command line

i want to count the number of times "I" repeats in the sentence
so i can't take args[0],args[1]... so how do i take this full sentence as a single thing in my program?

By enclosing it in double quotes, like this:

java MyClass "I AM LEARNING JAVA"

Then it'll all end up in args[0] - without the quotes.

Join your parameters into one string:

StringBuilder sb = new StringBuilder();
for (int i = 0; i < args.length; i++)
{
    if (i > 0)
    {
        sb.append(' ');
    }
    sb.append(args[i]);
}
String allArgs = sb.toString();

What else are you looking for that this very simple way of doing things doesn't accomplish?

Yes, you can; Rob has already told you how to iterate through the array with a for loop.
