Java - object for loop with condition?

This may sound silly but I couldn't find an answer by googling it.

When using a for loop in it's simplest form I can add conditions to break the loop in the for statement. example:

for(int i=0; i<100 && condition2 && condition3; i++){
    //do stuff
}

When using an object for loop like this:

for(String s:string_table){
    //do stuff
}

how can i add a condition to break the loop? I'm talking about adding conditions in the for statement. I know I can add the condition inside //do stuff part and break from there.

You cannot add anything else to the () part of the "enhanced for" statement. JLS § 14.14.2:

The enhanced for statement has the form:

for ( FormalParameter : Expression ) Statement

The type of the Expression must be Iterable or an array type.

(The "FormalParameter" means a variable declaration.)

The break; statement is the only way:

for (String s : string_table) {
    if (condition) break;
    // ...
}

You cannot do that you have to go by putting the if statements in the for loop.
