Is it possible for Java foreach to have conditions?
For example,
for(Foo foo : foos && try == true) { //Do something } Is there an equivalent to this, such that I can put an AND condition inside for?

No, a foreach simply works for each element.
If the purpose of forEach() is just iteration then you can directly call it like list. forEach() or set. forEach() but if you want to perform some operations like filter or map then it better first get the stream and then perform that operation and finally call forEach() method.
You can't.
The forEach method was introduced in Java 8. It provides programmers a new, concise way of iterating over a collection. The forEach method performs the given action for each element of the Iterable until all elements have been processed or the action throws an exception.
No.
You could use a while loop instead.
Iterator iterator = list.iterator(); while(iterator.hasNext()) { ... } No, there is nothing like that. The "enhanced for loop" is a completely separate construct that does nothing except lopp through the iterator returned by its Iterable parameter.
What you can do is this:
for(Foo foo : foos) { //Do something if(!condition){ break; } } If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
