Thread: Rearranging string input.

Hey guys,

Looking at a past exam paper of mine and one of the questions says:

Using only the Scanner, String and System classes, write a basic program that prompts the user to enter Hair color, Eye color and Age, (all on one line), and then output the words in the order Age, Hair color, Eye color.

I have been stuck for awhile, I tried String[] split, but It didn't work. Help me please.

Welcome to the forum
It is difficult to see a problem without seeing the code.
Post the code and explain what you are having trouble with

post the code

There are many ways even a simple program like the one you describe will fail, earning the description, "It didn't work." The chances are very slim that we correctly guess which one of those ways (possibly many) failed in your case, so offering advice is pointless.

Post the code!

Prompt the user for the info, then use the printf to format your strings.
Example:
System.out.println( "Enter the hair color, eye color, and age, separate each with a space." );
age = console.next();
hair = console.next();
eye = console.next();
printf("%s %s %s", age, hair, eye);

That's IF I am understanding your question correctly......

public static void main(String []args){
Scanner scanner=new Scanner(System.in);
System.out.println("Enter user age,hair color,eye color");
int age=scanner.nextInt();
String hcolor=scanner.next();
String ecolor=scanner.next();
System.out.println("Age "+age+" hair color "+hcolor+" eye color "+ecolor);


}

If i understand your problem properly,this code will help you,java provides string concatenation facility by which you can display the message in one line.

The issue with posting code as you both have in post #5 and #6 is that you don't know what the original post meant. Not to mention if that is indeed what he was looking for you have just given him the code and spoon fed him the answer preventing him from finding out the issues he was having.

That being said it seems the instructor is asking for:

Ask user for Hair color, Eye Color and Age
User inputs int a single line all 3 values
Program breaks down the string and separates the values
Display values in a new order

The code you both provided prompts the user for 3 different values in 3 separate lines. Lyumi post the code you created and are having issues with and we can help you pinpoint the reason it is not working as you want it.
