Basic Properties of a String

Length of a string

The length of a string is the total number of characters present in that string. For example, the length of the string “I love Java.” is $12$.

You must be thinking that it’s hectic to count every character to find the string’s length. The example above was not even long. What if we get a string with a long length, maybe with 100 characters in it? Will we have to count it character by character?

Don’t worry! There’s no need for us to count. Let the computer do it! Let’s write a program in Java that will calculate the length of a string.
