Thread: HELP ME WITH THIS CODE. I"M ABOUT TO SMASH MY LAPTOP SCREEN

reply to me at honestsportstalk@gmail.com or here.. i will be checking this ever hour.

thanks norm, i editted it. and no, nextLine() completely skips my input and essentially closes my program. I need a "next" string that will take the whole entire input at g = ps.next(); .... and not just the first word... cause the user was supposed to enter two words... i get that the e.contains(g); catches those two words at string 'g' and compares it to string 'e'. If those two words (really the first word, as it is only reading the first word) is in string e, then the codes executes in the 'if' statement. if not, the error message pops off.... So basically I'm asking you, how do you do this loop or get the next word in the scanner.. I get that all the words the user inputs goes in a "pool". The first word in the "pool" is taken and inputted, and the rest in the "pool" remains there to be retrieved... Or maybe when you press Enter it clears the other words in this "pool". I am not sure.

But after I figure out a way for the two words to be inputted in the code, and not just one, i guess I would have to do a 'greater than' or 'less than' statement.... because string 'g' takes two words from string 'e' (via the user entering them). And I am supposed to print which word appears first of the two, in the initial string 'e'. So somehow I would have to get the integer values of the two words in respect to their positions in string 'e', and assign them to integers or strings. and do a 'if a>b print a, else print b' or something like that. HELPPPPPPP. how do I get the codes to take both words in the input using the string.next(); and not just the first word!!!!

Can you post the code where that happens and copy the console from when you executed the code.
On windows: To copy the contents of the command prompt window:

nextLine() reads a whole line.
next() reads the next token.

Hello, I changed it from g = ps.next(); to g = ps.nextLine(); Like before, the program does not ever wait for me to input anything, and skips to the next line, which I coded to close out the program.. Here is a copy:

<C:\Users\Red Bull\Documents\Documents\School\Programming\Programs>java BestClass
 
The best class ever,,, and the best dxy ever
The best class ever, and the best day ever.
 
Type any word to see if it is in the string:
if
The string does not contain your word!
 
The second word capitalized in the previous string makes this string:
The Best class ever, and the best day ever.
 
A new string with the 'r' removed looks like this:
The Best class eve , and the best day eve .
 
The third word capitalized in the previous string makes this string:
The best Class ever, and the best day ever.
 
The last word capitalized in the previous string makes this string:
The best class ever, and the best day Ever.
 
Step 4 commas is replaced using the substring method:
The best class ever, and the best dxy ever
 
Step 5 'dxy' is replaced with 'day' using the substring method:
The best class ever, and the best day ever
 
Pick two words out of the sentence and type it, separating it by a space:

there has got to be a loop or something that I can use to retrieve the other word in that input.... I'm beginning to hate this professor

nope... doesn't work. When I use nextLine() , it still skips the input part, and it prints g=< , most likely interpreting that "g="+g+"<" literally . If I don't use nextLine(), and instead use next() , it still takes the first word only, and prints the "g="+g+"<" literally also...

It prints g=< and still doesn't wait for me to input. If I change ps.nextLine() to ps.next(), it'll print my first word and g=<

If the code has called the next() method, there is a newline left in Scanner's buffer.
Call nextLine() to read that from the buffer before using nextLine() to read a whole line.

MUHAHAHAHAHHAHAH BUAHAHAHAHAH MUAHAHAHAH HAHAHA BUHAHAHA MUHAHAHA I HAVE FIGURED IT OUT. AND YES, THANKS FOR YOUR HELP MEN. WITH THE NEXTLINE() PICKING UP THE NEXT WORD IN THE INPUT, MY INSTRUCTOR DID NOT SHOW US THIS AND EXPECTED US TO FIND IT OUT. I KNOW HE DID THAT ON PURPOSE SO THAT WE WOULD HAVE TO GO ONLINE AND FIGURE IT OUT. AND I PROMISE YOU, THIS WILL NOT BE THE LAST TIME THAT I WOULD VISIT THIS WEBSITE. YOU GUYS ARE BETTER THAN STACKOVERFLOW.COM . THEY WERE LAUGHING AND SH**T AT ME...

HERE'S WHAT I DID... I DID USE G =NEXTLINE() AFTTTTEERRRR I USED G = NEXT() , AND I ASSIGNED BOTH OF THEM TO DIFFERENT STRINGS... THEN I USED THE INDEXOF() TO GET BOTH OF THEIR POSITIONS... THEN USING A SIMPLE BOOLEAN IF/ELSE STATEMENT, WHICH EVER WAS LOWER IN INTEGER I WOULD PRINT THAT STRING(OR WORD)... I HAD TO TRIM THE SECOND WORD BECAUSE OF THE SPACE... I WILL POST NOW... HOPEFULLY NO ONE AT MY SCHOOL COMES ON THIS WEBSITE AND STEALS MY CODE... OR I MIGHT BE MORE INCLINED TO GO COLUMBINE (OK.... I DIDN'T MEAN THAT. PLEASE DON'T REPORT ME.... IT WAS JUST A METAPHOR... I AM SANE)...

IIIIIIIIIII AMMMMMMMMMMMMMM A GENIUSSSSSSSSSSSSSSSSSSSSSSSSS MUAHHAHAHA BUAHAHA BUHAHAHH AMUHAHAHHAHA. I AM GREATTTTTTTTTTTTTTTT. MUHAHHAHAHA HAHAHHA.... MOVE OVER BILL GATES, MOVE OVER SUCKERBERG... IIII RED BULLL AM DA BESTTTTTTTTTT PROGRAMMER. HAHAHHAHAHAHHAA... GENIUSSSSSS. HAHAHHAHAHAHAHHA RESPECT ME NOWWWWW

dam... found another logic error, lol... it reads "The" and "the" as two different words.... help me men... there is like a java string that would ignore the case...

how do I use the ignorecase while using the boolean string.contains? or do I have to a make an if/else statement like "if string is capitalized, switch to lowercase"???

Hey Norm, did I piss you off?

I HAVE FIGUREEEDDD IT OUTTTT. I AMM GREATTT. just a simple e = e.toLowerCase(); before I start collect the user's input from string's g and h/i.... HAHAHAHAHHAHA. some1 gimme a high five... now i got a harder assignment now... i gotta write a program to calculate equations using the ax+by=c , where a and b are constants (1-99 integers, and i do print the 1), and x and y are obviously variables (integers, maybe I'll use double or float).... I am going to work on this tomorrow, but i'd probably need ure guys help... Piece out
