what is foreach loop and its uses?

Question

how can we use for each loop examples and syntax?

Answer 1

If arr is an integer array, then you can access it using the following foreach loop:

for(int item: arr) {
System.out.println(item);
}

It means you're defining each element of that array as item. So you can access the elements using item instead of arr [index]. foreach loop checks all elements of a collection from first to last, so you don't need the concept of index to access elements.

So the basic syntax is:

for(type variable_name : collection_name){
// access using variable_name
}
