Convert Char to String

Introduction

In this lab, you will learn how to convert a character char to a string String in Java.

Convert Char to String Using valueOf() Method

• Open your terminal and create a Java file using the below command:

  touch ConvertCharToString.java

• Open the file using a text editor and paste the below code:

  public class ConvertCharToString {
    public static void main(String[] args) {
      char ch = 's';
      System.out.println(ch);
      String str = String.valueOf(ch);
      System.out.println(str);
      System.out.println(str.getClass().getName());
    }
  }

• Compile the Java code using the below command in the terminal:

  javac ConvertCharToString.java

• Run the Java code using the below command in the terminal:

  java ConvertCharToString

• The output will be:

  s
  s
  java.lang.String

Convert Char to String Using toString() Method

• Open the same ConvertCharToString.java file in the text editor and replace the main method with the below code:

  public static void main(String[] args){
    char ch = 's';
    System.out.println(ch);
    String str = Character.toString(ch);
    System.out.println(str);
    System.out.println(str.getClass().getName());
  }

• Compile the Java code using the below command in the terminal:

  javac ConvertCharToString.java

• Run the Java code using the below command in the terminal:

  java ConvertCharToString

• The output will be:

  s
  s
  java.lang.String

Convert Char to String Using + Operator

• Open the same ConvertCharToString.java file in the text editor and replace the main method with the below code:

  public static void main(String[] args){
    char ch = 's';
    System.out.println(ch);
    String str = ""+ch;
    System.out.println(str);
    System.out.println(str.getClass().getName());
  }

• Compile the Java code using the below command in the terminal:

  javac ConvertCharToString.java

• Run the Java code using the below command in the terminal:

  java ConvertCharToString

• The output will be:

  s
  s
  java.lang.String

Summary

In this lab, you have learned how to convert a character char to a string String in Java using different methods. You can use either valueOf() or toString() methods or plus (+) operator to convert a character to a string.
