Java string length() is an inbuilt function that is used to get the length of a Java String. Often, it is required to find out the length of a String, and for such scenarios, Java provides the inbuilt java.lang.String.length() method. Length of the String is essentially the number of 16-bit Unicode characters it contains. In the case of an empty String, it contains zero characters. However, in the case of a null string, this method will throw NullPointerException.
