How to Convert a Char to a String in Java: What are the Best Methods?

Converting a Char to String

In scenarios where you possess a character and require its string representation, a convenient conversion method exists within Java. To seamlessly accomplish this transformation, you can leverage the String Builder class, a renowned tool in Java for crafting strings. Here's how to execute this process efficiently:

Utilizing the Character Class:
For precise and designated char-to-string conversion, employ the Character.toString(char) method. Notably, it grants comparable functionality to String.valueOf(char).

Concatenation as a Swift Alternative:
If simplicity is your pursuit, string concatenation offers a shortcut to achieving your conversion goals. Simply type "String s = "" 's';" to swiftly create a string from a character. However, discerning developers discern that this tactic ultimately compiles to "String s = new StringBuilder().append("").append('s').toString()". Recognizing this can steer you toward more efficient alternatives like String.valueOf(char) which employs a more streamlined char[] wrapping technique.
