Vielen dank, aber es hat nicht funktioniert!

I tried



if ( firstLetters[x] != 0)


and still got the extra space output after "a".

PROBLEM SOLVED.

Can someone find the error in my code that's creating an extra space in my output sentence, "a ay" ? It should read "aay" . I don't see it. Also, how would I remove the "." from...

Wow. Thank you. I didn't even import java.util.Arrays.toString, and my program still compiled and executed. Weird.

This is what I tried.

So, I see that regex is a delimiter. Now, I don't understand this code:



public String[] split(String regex)


Where in that code is the string...

I found this on Stack.

"The easiest and best answer I can think of is to use the following method defined on the java string -

So I can use the split method defining substrings to extract from the main string? Would I import java.util.* and create a Matcher object to hold whitespace? I'm still lost..

That was it! You're a lifesaver! Thank you!

This program is supposed to simulate a fuel gauge and odometer. I am having trouble because two class objects in two different classes, referencing the same variable in a third class, are reporting...

Hey, I know what you mean; I use this all the time to demand the user enter an integer:




Scanner input = new Scanner(System.in);

System.out.println("Enter an integer: ");

Norm is like Google. Endless amounts of information. I'm amazed.

I haven't examined your whole program, but an easy way to get the menu to repeat itself is to wrap the whole thing in a while loop, with a boolean condition, like:




boolean done = false;

Post retracted. Good advice already given..

Are you using .floor and .ceil to lower/raise each random double then type-casting to int, to ensure two different results? If so, creative. Well done!
