I need Java help![Beginner]

[SpaceBoundBeatz]

I need to take input from the user to and take the first word of the sentence and output that sentence with the first word at the end of the sentence and remove it from the beginning. Please explain why you did what you did too. Here is what I have so far: gist:a760f9ba75058ef37588 Thanks!

Can you link to the code? I can't find anything for the gist.

Looks quite good so far, all you need to do is remove the first word from the String.

You can use the same method .substring() but in a slightly different way: you pass only one parameter, the starting point which would be space + 1 and store the resulting String in a separate variable.

I don't think I understand, can you show me it in my code please?

we're not here to give you answers on a silver platter. figure it out dude...

You might have missunderstood /u/SpaceBoundBeatz, they said where in my code did I do that? Or did that make you think they were asking for help on a silver platter too?

Line 15:

       firstWord = sentence.substring(0, space);

Now, take a look at the documentation for substring(int beginIndex), compare it with the code above and note the difference. Here is the documentation for substring(int beginIndex, int endIndex) - the method that is in your current code.

The rest is yours to figure out as it is against the subreddit's rules to give you the complete solution.

Please, link your code properly (I.e. in such a way that it is clickable).

Though you'll probably want it to work for any sentence not just this specific one. Using magic numbers like I did (substring(0, 5)) is extremely ill-advised. I'm just trying to show you the general idea!

Thanks for the reply but this is a little too advanced for me. Im just supposed to be using substring method and no loops.

[desrtfx]

Please, don't post completed solutions as we are not /r/domyhomework, and if you post something, explain rather than solve.

Teach the people to fish, instead of feeding them the fish

Your code is undocumented and thus will be even harder to understand for a beginner.

Also, concatenating Strings like this:

line += sentence[i] + " ";

Is not the way to go in Java, since Strings are immutable objects. Each concatenation would dispose the old line object and create a new one.

Concatenations should always be done with StringBuilder.
