Description: String is probably the most commonly used class in Java’s class library.The obvious reason for this is that strings are a very important part of programming. String functions are used in computer programming languages to manipulate a string or query information about a string (some do both).Most programming languages that have a string datatype will have some string functions although there may be other low-level ways within each language to handle strings directly. 3.You have some basic knowledge about Regular Expressions. String Length A String in Java is actually an object, which contain methods that can perform certain operations on strings.
