The Command.. break; in Java what if.?

Question

What if we have an if statement inside a for loop, would it stop the loop or the if condition...

Example:

for (int i = 0; i < array.length; i++) {
           


        

Answer 1

The selected answer is almost right. if break statement be mixed by label then it can be used in if statement without needing to be in a loop. The following code is completely valid, compiles and runs.

public class Test {
    public static void main(String[] args) {
        int i=0;
        label:if(i>2){
            break label;
        }               
    }
}

However if we remove the label, it fails to compile.

Answer 2

It will stop the loop.

Answer 3

Once the condition is met and the statement has successfully been executed (let's assuming no exception is thrown), then the break exits from the loop.

Answer 4

for (int i = 0; i < array.length; i++) {
    jumpIf: if (condition) {
        statement;
        break jumpIf;
    }
}

Answer 5

You can break out of just 'if' statement also, if you wish, it may make sense in such a scenario:

for(int i = 0; i<array.length; i++)
{
CHECK:
   if(condition)
   {
     statement;
     if (another_condition) break CHECK;
     another_statement;
     if (yet_another_condition) break CHECK;
     another_statement;
   }
}

you can also break out of labeled {} statement:

for(int i = 0; i<array.length; i++)
{
CHECK:       
   {
     statement;
     if (another_condition) break CHECK;
     another_statement;
     if (yet_another_condition) break CHECK;
     another_statement;
   }
}

Answer 6

a break statement (and its companion, 'continue', as well) works on a surrounding loop. An if-statement is not a loop. So to answer your question: the break in your code example will jump out of the for-loop.
