Thread: school project

Hey Im new to java and have a pretty basic question. I have a homework assignment in which i have to write a program that reads a line of text as input, then moves the FIRST word to the END of the sentence.
So if I typed "Hello my name is Robin", it would read "My name is Robin hello" (Note the first letter became capital). Any help would greatly be appreciated!

What have you done so far?

not much, i really dont know where to get started...

import java.util.Scanner; public class lab4 { static Scanner keyboard = new Scanner(System.in); public static void main(String[]args) {   System.out.print("Type a short sentence for me: " ); String sentence; sentence = keyboard.nextInt();   // i really dont know where to start. If you could guide me in the right direction, i would appreciate it

this link : Java 2 Platform SE 5.0 Will tell you about the next() methods, nextInt() is to get a number, you want next() or nextLine()

I think it has to do with the "Methods in the Class String" section of my textbook, however, I don't see one which switches words. Also, if the user puts in their own input, I won't know which index the last word starts at. This is very frustrating! : (

thanks I'll check that out

Check out the charAt() or indexOf() methods of the String class

im still stumped on this...I know how to switch letters around with a sentence, because I can see all of the indexs. But since the sentence has to be user input, how am I supposed to know what the indexs are?

I really would appreciate some help. This project is due tomorrow....

If you have a space between words, read it from the document with inFile.next().

That will stop every time it has a line.

I'm not sure if it'll go to the next line after that, but if not, it can read in each word.

split the sentence using split("//s") method, this will return u an array of String. u can then put the entry on idex 0 to the end of the array and print.

i hope its not too late for your assignment..

  import java.io.InputStreamReader; import java.util.Scanner;   class Test{ public static void main(String[] args) { Scanner sc = new Scanner(System.in);   String sen = sc.nextLine();   String[] words = sen.split("\\s");   String newS = "";   for(int x=1;x<words.length;x++){ newS = newS.concat(words[x])+" "; }   newS = newS.concat(words[0]);   newS = newS.toLowerCase();   char s = newS.charAt(0);   String x = (s+"").toUpperCase();   String endString = x+(newS.substring(1, newS.length()));   System.out.println(endString);       }   }

Don't show off. Posting full solutions deprives the original poster of a learning opportunity, and is against the spirit of a forum.
