In this demonstation you will be shown how to get the length of a string using the length() function in Java 

The length() is a built-in Java function that returns its length by appending to a string. All the white spaces and special characters are calculated as part of the length.

Here is how you get the length of a string in Java

• Use the length() method 

• Spaces within the string will be counted as well

Here is an example without white space:

String str = "string";
System.out.print(str.length()); //Outputs 6

As you can see above, the length() method is appended to a string which in this case is the word "string". It counts the amount of letters in the word.

Here is an example with space:

String str = "this is a string";
System.out.print(str.length()); //Outputs 16

The length() method will count the white space as part of the length of the string.

Here is an example with white space and special character:

String str = "this is a string!!";
System.out.print(str.length()); //Outputs 18

The length() method will count the white space and special characters as part of the length of the string.
