Notes

In Apex, the toUpperCase() method is a string method that converts all the characters in a string to uppercase.

Here's an example:

String originalString = 'Hello, Apex!';
String uppercasedString = originalString.toUpperCase();

In this example:

originalString is a string variable containing the original text.
originalString.toUpperCase() is a method call that transforms all characters in originalString to uppercase.
uppercasedString is a new string variable that stores the result.

After executing this code, uppercasedString would contain the value 'HELLO, APEX!'. This method is useful when you want to ensure that string comparisons or outputs are case-insensitive or need to standardize the case of characters in a string.
