In Java, a string is a sequence of characters. Strings are immutable, which means that once a string is created, its contents cannot be changed. To check the contents of a string, you can use the following methods:
`length()` – returns the length of the string.
Checking for empty strings in Java involves determining whether a given string object contains any characters. An empty string, often referred to as an empty string, has no characters and has a length of 0. In Java, strings are immutable, meaning their contents cannot be changed once created. As a result, checking for emptiness is a common operation when working with strings.
There are several methods to check for empty strings in Java. One common approach is to use the isEmpty() method of the String class. This method returns a boolean value indicating whether the string is empty (i.e., has a length of 0).
