Thread: Prompt user to repeat

Use continue where you want your loop to iterate again but don't forget to iterate the value before moving it to continue statement.

continue;

I looked up some tutorials with the continue statement but I cant seem to see how it would work in this code?

class Mock  
{  
    public static void main(String[] args)  
    {  
 
 
    int ans= 0;  
    int loop =0;  
    int i=1;  
    int end= 0;  
 
    do  
{  
 
    System.out.println("Do u like number "+i)  
    ;i++;  
    ans = EasyIn.getInt();  
 
 
 
    if (ans == 1)  
{  
    System.out.println("Good");  
}  
 
 
 
    else if (ans == 2)  
{  
    System.out.println("Thats OK!");  
}  
 
 
    else  
{  
    --i; --loop;  
    System.out.println("1 or 2 only!!");  
    System.out.println();  
}  
    {  
    loop++;  
    }  
}  
    while (loop <10);  
    }  
}

The OP seemed to say that he needs to continue if certain condition occur and continue processing further statements in other case.

I would say add an if statement right before the end of the do-while loop.

if(loop == 9)
{
     System.out.println("Do you want to go again?\nYes or No";
     Scanner scan = new Scanner(System.in);
     String i = scan.nextLine();
     if(i.equalsIgnoreCase("Yes"))
          loop = 0;
}

I didn't disagree with your pseudocode or the solution you provided to the OP. What i told you is, i thought OP needs to execute number of statements if certain condition fulfils else OP doesn't want to execute (in a loop), that's why i pointed towards continue statement. May be lack of understanding of the problem or whatever.

hmm If your new to loops, Stick to simple code such as JOptionPane

for example a string varible getting data from the optionpane

... 
 
_strString = JOptionPane.ShowInputDialog(null, "Would you like to restart?");
_strString.toLowerCase();
 
 
if(_strString.equals("yes"))
{
    // enter code if the user enters yes
}
else if (_strString.equals("no"))
{
     // Enter code if the user enters no
}
else
{
     // Enter code if the user enters invalid choice
}
 
...

Ignore my case sensitive if its wrong xD..

Simple but works and easily understood.

Junky stop being such a jerk to me. See this example

int i=10;
while(i<100){
if(i%2==0){
i++;
continue;
}else{
System.out.println(i);
i++
}

So, what do you say about the usage of continue here?
I've never denied accepting my fault and i am not trying to justify my advice. WHat i've tried to tell you is the understanding what i got from OP's post. Hope you understand and better stay on the topic rather teaching me about what i thought or not.
Sorry to be so hard.

    i += 2;
}

Will you mind giving me a break? I already told you, i adviced what i thought OP is asking about. Now, better stay away and stick to the topic rather scratching my butts.

First, i never got time to argue with the people who have nothing else to do. Second, i already told you that the advice given to OP by me was for some other scenario, what i thought and i told you earlier. Now, what do you want to prove? Either you are a Java legend? Grow up and get some life Junky. Better stop this converstaion here coz i am not gonna admit if i was wrong with the advice. Coz i advised about the scenario i understood. Yeah you can say that i misunderstood but still it's worth proving me wrong.
