How to convert a char to a String

Question

I have a char and I need a String. How do I convert from one to the other?

Answer 1

You can use Character.toString(char). Note that this method simply returns a call to String.valueOf(char), which also works.

As others have noted, string concatenation works as a shortcut as well:

String s = "" + 's';

But this compiles down to:

String s = new StringBuilder().append("").append('s').toString();

which is less efficient because the StringBuilder is backed by a char[] (over-allocated by StringBuilder() to 16), only for that array to be defensively copied by the resulting String.

String.valueOf(char) "gets in the back door" by wrapping the char in a single-element array and passing it to the package private constructor String(char[], boolean), which avoids the array copy.

Convert Char To String

1. public class CharToString_toString {
2. public static void main(String[] args) {
3. //input character variable.
4. char myChar = 'g';
5. //Using toString() method.
6. //toString method take character parameter and convert string.
7. String myStr = Character. toString(myChar);
8. //print string value.

Java char to String Example: String.valueOf() method

Let's see the simple code to convert char to String in java using String.valueOf() method.

1. char c='S';  
2. String s=String.valueOf(c);  

Let's see the simple example of converting char to String in java.

public class CharToStringExample1{  

public static void main(String args[]){  

char c='S';  

String s=String.valueOf(c);  

System.out.println("String is: "+s);  

}}  

1. Output:

   String is: S
