    Default 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!

    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! : (

    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?

    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.

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

    Your first mistake was leaving it to the last minute to complete. Never a good idea!

    relixus has offered you a solution. Hopefully you have learnt something along the way.
