The **`for each` loop** is another variant of the `for` loop that iterates over a list or array of elements. The same function is done on each item.



# Syntax

The syntax starts out with the standard `for` keyword followed by parentheses or simple brackets. The brackets contain an object name of some data type followed by a colon followed by an array of the same data type as the declared object.

```
for (datatype item : array){

   statements using item
}


class ForEach {
    public static void main( String args[] ) {
        int nums[] = {23, 48, 66, -20, 24, 9, 10};
        int max = -9999;
        for (int number: nums){
            System.out.print(number + " ");
            if(max < number)
                max = number;
        }

        System.out.println("\nThe maximum element in the array is " + max);
    }
}

class Forloop {
    public static void main( String args[] ) {
        int nums[] = {23, 48, 66, -20, 24, 9, 10};
        int max = -9999;
        for (int i = 0; i < nums.length; i++){
            System.out.print(nums[i] + " ");
            if(max < nums[i])
                max = nums[i];
        }

        System.out.println("\nThe maximum element in the array is " + max);
    }
}

# Limitations

1. The `for each` loop does not modify the contents of the actual array since the iteration object is just a copy of a single array element.
2. The `for each` loop cannot iterate over an array in reverse.
3. The `for each` loop is limited to a single step per iteration.
4. The `for each` loop does not keep track of the current index of the array it's iterating over.
5. The `for each` loop cannot handle multiple decision-making statements at once.

What the `for each` loop offers is enhanced readability and fewer chances of programming errors.
