Orpaned case

I have a orpaned case error and im not sure where i am missing anything. Probably just needs another set of eyes to find it. thank you in advance

Here is the error code :
C:\Users\winte497\Documents\FSMValue.java:109: orphaned case
case 6: if ((ch >= '0') && (ch <= '9'))

Here is my program:

import java.util.*;
public class FSMValue {

  public static void main(String[] args) {

	int x;
	String s;
	char ch;
	int state;
	double value;
	double whole_part, dece_part;
	int sign,power;
	Scanner input = new Scanner ( System.in );

	System.out.print("Enter Number or enter CTRL z to exit =====> ");
	while (input.hasNext())
	{
 		s = input.nextLine();
 		s = s + ' ';
 		x = 0;
 		state =1;
 		value =0;
 		whole_part =0;
 		dece_part = 0;
 		sign =1;
 		power =10;
		while ((state != 7) & (state != 6))

well ... no offence, but you've made a mess out of your usage of
{'s and }'s.

starting from line 108.

not to mention the fact that you're using variables you didn't declare or initialize.
you may want to spend some minutes cleaning your code.
