Length Of String In Java

In simpler words, the number of characters that a string contains is called the length of a String in Java. If you want to find the number of characters of a String, an inbuilt method is available in Java known as length(). The length of a Java string and the Unicode characters of the String are the same.

The length() method 

An inbuilt length() method of the Java String class can be used when the length of a String has to be calculated. Strings are objects that are created with the help of the String class in Java, and the length() method belongs to this class and is a public member method. Hence, any type of string variable can use this method with the help of the . (dot) operator. The length() method calculates a String’s total number of characters.
