How to find the length of element at any index of array in java?

Question

Please I really need an answer. I know how to find length of array but if I need to find the length of particular element at any index of array,then?

Answer 1

The below method is one of the solutions to your question -

Assuming your array is of the String[] type.

 

/**
* @param index - the index in the array
* @param array - the array
* @return the length of element at index of array.
*/
public static int getLengthOfElementInArray(int index, String[] array){
    return array[index].length();
}

 

Note that this is the basic code and it does not handles any exceptions. For example, if the array that you are passing is null or if index that you are passing is greater than the length of array, it will give exceptions.
