Concatenate string variables in apex
Concatenation is the process of joining two or more strings variables together. To concatenate strings in apex, use the + operator.
An example of cocatenation of strings would be finding the full name from the given first name and last name.
Why concatenate strings in apex
In Apex, string concatenation is used to combine multiple text values into one. For example, you can merge street, city, state, and postal code fields to display an address in a single line. This makes it easy to format and present data clearly.
Note: Adding a space between strings in Apex creates proper word separation
Following is an example of concatenating two strings in apex.
In the above example, we concatenated two string variables string1 and string2 and assigned the result to another string variable finalString.
