Why this program doesnt work... what it supposed to do

Question

import java.io.*;
public class try1 {
     public static void main(String[]args)throws Exception
          BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
          double int1=1;
          double int2=1;
          double int3=1;
          double x=0;
          System.out.println("Euclids Instruction");
          System.out.println(" ");
          System.out.println("Enter 1st:");
          int1=Integer.parseInt(br.readLine());
          System.out.println("Enter 2nd:");
          int2=Integer.parseInt(br.readLine());
          int3 = int1 - int2;
          System.out.print("Series:");
          System.out.print(int3);
          do
               if (int2>int3)
                    int1=int2;
                    int2=int3;
               int3 = int1 - int2;
               x=int3;
               System.out.print(" " + int3);
               else if(int2<int3)
                    int1=int3;
               int3 = int1 - int2;
               x=int3;
               System.out.println(" " + int3);
          while (x<0);
          System.out.println("GFC" + " " + int3);
IT SHOULD BE LIKE THIS
sample is
first input is 100
sec input is 70
series 30 40 10
GFC should be 10
but out put is 30 40
GFC 40
it doesnt follow the while int3==0
please help

Answer 1

import java.io.*;
public class try1 {
public static void main(String[]args)throws Exception
BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
double int1=1;
double int2=1;
double int3=1;
double x=0;
System.out.println("Euclids Instruction");
System.out.println(" ");
System.out.println("Enter 1st:");
int1=Integer.parseInt(br.readLine());
System.out.println("Enter 2nd:");
int2=Integer.parseInt(br.readLine());
int3 = int1 - int2;
System.out.print("Series:");
System.out.print(int3);
do
if (int2>int3)
int1=int2;
int2=int3;
int3 = int1 - int2;
x=int3;
System.out.print(" " + int3);
else if(int2<int3)
int1=int3;
int3 = int1 - int2;
x=int3;
System.out.println(" " + int3);
while (x<0);
System.out.println("GFC" + " " + int3);
FIRST YOU HAVE TO ENTER 2 INPUTS
THE FIRST INPUT("INT1") IS SUBTRACTED FROM THE SECOND INPUT("INT2") THE OUTPUT WILL BE THE THIRD VARIABLE WHICH IS "INT3"
THE SYSTEM WILL THEN CHOOSE FROM INT2 OR INT 3 IF WHO'S GREATER OR LARGER
IF THE SYSTEM DETECTS THAT INT2 IS LARGER THAN INT3 THEN INT1=INT2 AND INT2=INT3
ELSE IF THE INT3 IS GREATER THEN INT3 WILL BE THEN INT1=INT3 AND INT2 WILL REMAIN THE SAME
UNTIL IT REACH THE CONDITION INT3==0
SAMPLE OUTPUT SHOULD BE
<INPUT 1ST>10
<INPUT 2ND>2
OUTPUT SHOULD BE IN
SERIES LIKE 8 6 2
GFC IS 2
BUT WHATS HAPPENING IS IT PRINTS 8 AND 6 .. AND THE GFC IS 6 ...
ERRR DID I EXPLAIN IT RIGHT?
