    Default Help with string output

    I have to write a program that outputs all possible permutations for three input strings. My code works fine except for one problem: if I put a space in between words, it takes the second word as a second input string. How could I use the following code but allow for blank spaces?

    // Chapter 2 programming exercise 17)
    // Program to give all six permutations for 3 inout strings
     
    import java.util.*;
     
    public class Ch2_PrExercise17
    {
    	public static void main(String[] args)
    	{
    		Scanner console = new Scanner(System.in);
     
    		//variable declaration
    		String a, b, c, aa, bb, cc, dd, ee, ff;
     
    		//executable expressions
    		System.out.println("This program will allow you to input three phrases and it will give you all the permutations.");
    		System.out.println("Please press Enter after each entry.");
    		System.out.println();
     
    		System.out.println("Enter the first phrase: ");
     
    		a = console.next();
    		System.out.println();
     
    		System.out.println("Enter the second phrase: ");
     
    		b = console.next();
    		System.out.println();
     
    		System.out.println("Enter the final phrase: ");
     
    		c = console.next();
    		System.out.println();
     
    		//calculations
    		aa = a + " " + b + " " + c;
    		bb = a + " " + c + " " + b;
    		cc = b + " " + a + " " + c;
    		dd = b + " " + c + " " + a;
    		ee = c + " " + a + " " + b;
    		ff = c + " " + b + " " + a;
     
    		//output requirements
    		System.out.println(aa);
    		System.out.println(bb);
    		System.out.println(cc);
    		System.out.println(dd);
    		System.out.println(ee);
    		System.out.println(ff);		
     
    	}
    }

    I put a space in between words, it takes the second word as a second input string.
    Are you talking about what the Scanner class reads in from the user?
    The Scanner class has several methods to read in different types of data.
    Look at some of its next... methods to see if any of them will read in what you want to be read.

    To see how they all work, write a small test program and use some of them with different combinations of user input to see what they do. Read in a value and print it.
