Question

How would I write a jave program to solve a random guessed number between 1 and 1000000? I get confused when trying to do a while loop.

while(JOptionPane.showConfirmDialog(null, "Is your number less than or equal to"+(h-((h-l)/2))+"?","warning",option)==JOptionPane.YES_OPTION){
           h=(h-((h-l)/2));
           l=l;
           JOptionPane.showMessageDialog(null,   "Low:"+l+"      High: "+h);}
           //dialogResult=JOptionPane.showConfirmDialog(null, "Is your number less than"+(h-((h-l)/2))+"?","warning",option);

           if (JOptionPane.showConfirmDialog(null, "Is your number lesss than or equal to"+(h-((h-l)/2))+"?","warning",option)==JOptionPane.NO_OPTION){
              
               JOptionPane.showMessageDialog(null,   "Low:"+l+"      High: "+h);
               l=(h-((h-l)/2));
               h=h;
              

               JOptionPane.showMessageDialog(null,   "Low:"+l+"      High: "+h);  
               if(h==l){
                   JOptionPane.showMessageDialog(null, "Your number is: "+l);
                  
               }

This is what I have tried, and it doesn't work. It just ends the loop, but I want it to continue to go back and forth till it gets and answer. Thanks for any ideas
