Stopping the loop

Question

for(int j=0;j<10;j++){
        if (xx2==0){
            f =xx1*(Math.pow(x,p))+xx3;
            derF =   xx1*(p*(Math.pow(x,(p-1)))); 
            get3=x-(f/derF);
            Arr[j+1]=get3;
            String roundXn = df3.format(Arr[j+1]);
            String roundfxprime = df3.format(derF);
            String roundfx = df3.format(f);
            if (Arr[j]==Arr[j+1])
            {
                break;
            } 


            //x=x2;
            System.out.println("\n" + j+"\t" + x +"\t" + roundfx +"\t" +roundfxprime +"\t" +roundXn); 
            //roundXn = Convert.parseInt(
            Double Xn1= Double.parseDouble(roundXn);

            x = Xn1;

Code result:

I want the loop to stop at 3rd iteration, but the loop still continues. How do I stop it?

What is xx2 ? First, read how to ask a question and then I can help — FallAndLearn, Apr 07 '16 at 07:18

In the output. The iteration still continues.. Its supposed to stop at 3 iteration. — Randy Corpuz, Apr 07 '16 at 07:25
@FallAndLearn xx2 is a user input. If he input 0 the condition is executed — Randy Corpuz, Apr 07 '16 at 07:27
3rd Iteration is only valid for this case right? Other params may result in different count of iterations if I understand correctly. So you'll have to think about what exactly shall be the criteria to break the loop.Is it when Fx == Xn+1 ? If so, then you have to check for that condition. — Fildor, Apr 07 '16 at 08:16

@fildor the iteration is suppsoed to stop if the Xn+1 has the same result. — Randy Corpuz, Apr 07 '16 at 09:01

use

for(int j=0;j<3;j++)

or add a check in place where you need (maybe before if (xx2==0){)

if(j==2) break;

You can exit any lopp in java by using break;

Nope... The loop is supposed to stop if Xn+1 has the same value. – Randy Corpuz Apr 07 '16 at 09:12
@RandyCorpuz in that case I totally not understand your question. Xn+1 "has the same value" like what? – Alex Torson Apr 07 '16 at 09:26
Look at the screenshot i attach on my post. – Randy Corpuz Apr 07 '16 at 09:29
@RandyCorpuz if(x == Xn1) break; – Alex Torson Apr 07 '16 at 09:42
