![]() ![]() ![]() ToUpperCase() is appended at the end of the string value that you want to convert to uppercase. Here’s the syntax for the toUpperCase() method: toUpperCase() iterates through every character in a string and changes it to an uppercase character. The toUpperCase() method is used to convert a string to all-uppercase. That way, you can perform an equal comparison between the two values. For instance, if you store a user’s email address in all-lowercase (a common practice for security reasons), then you’ll want to convert their email address to lowercase when they try to sign in. This is important to note in cases where you are comparing two strings that may have different cases. ![]() Strings in Java are case sensitive, and so if you compare two strings, a true value will only be returned if the strings are identical and use the same cases. toUpperCase() and toLowerCase() are two examples of the many string methods available in Java. In Java, strings are stored as objects, which means they offer a number of methods that can be used to manipulate their contents. In Java, strings are declared by surrounding a sequence of characters by double quotes. Strings are sequences of one or more characters and can include letters, numbers, whitespaces, and symbols.
