Write a method that determines the total number of chars in each string of an array.

1 answer:

8 0

The total number of chars in each string is basically the size of each string.

Using JAVA:

String[] arr = {"hello", "my", "name", "is", "Felicia"}; int count = 0; for(int i = 0; i < arr.length; i++) { count = count + arr[i].length(); System.out.println("Characters in " + arr[i] + ": " + count); }

Output:
<span>Characters in hello: 5
Characters in my: 7
Characters in name: 11
Characters in is: 13
Characters in Felicia: 20</span>

}

Explanation:

Inside the action performed method, pass the strings in text box.
check if the value has been modified then do the relevant conversions inside the conditional statement.
When the user clears, it will not do to the inch conversion.
