break vs continue

[Kris Decker]

I am reading the RHE book right now.
I am a bit confused over the difference between a break and continue.
I understand that continue will cause you to break out of a loop (possibly to a place designated be a label).
Breaks seem to be essentially the same thing? Also, what is the scope of a break? For example:
for (int i=0; i<10; i++){
doSomething();
for (int j=0; j<i; j++){>
if (j=2){
break
}
doSomethingElse();
}
}
What happens with the break? Do you do the next iteration of i?

Continue will not break you out of the loop, it will take you back to the loop test and try to run the next iteration. While break will take you completley out of the loop.
For a detailed explaination and samples check out the JLS section 14.14

hope that clears it up for you

Hi Kris
The basic difference between continue and break is as follows:
continue takes the control to the first statement of the corresponding loop whereas the break statement exits from the loop.
Your programme is got many errors and so i have written my program modifying urs..which goes as follows
import java.io.*;
public class Test
{
public static void main(String args[])
{
for(int i=0;i<10;i++)
{
//doSomething();
System.out.println("Entered the outer loop");
for(int j=0;j<2;j++){ // for loop to be executed perfectly
if(j==0){ // requires boolean condition
break;
}
//doSomethingElse();
System.out.println("Entered the inner loop");
}
}
}
}
Here the if condition tests for value of j equal to o and then exits since it comes across break statement. Hope this example solves your doubt.

Thank you both for teh swift reply. I havent had the cnahce to read the JLS section yet, but I think I have a good grasp on teh difference between break and continue.
However, one question remains:
if there is a break within a nested loop, does it break out of ONLY the inner loop--or doest it break out of the inner and they outer loops (assuming there are two loops)?

break- it will break only from the loop in which this stmt is.
for(..)
{
for(..)
{
if(condition) break;
}
}
-----
If u hav two loop say out and in
out:for(..)
{
in: for(..)
{
if(condition) break out;
}
}
only now u can break outer loop.Even if u hav more than 2 loops
with lable u can break,whichever loop u want.
Hope this helps,
(sorry my explanation is not good,i am in hurry now)
