Convert char array to string in java

Let’s learn convert char array to string in java.

Convert char array to string in java

To convert a char array to a string there are two ways.

Convert char array to string using Constructor:

Here first create String object and pass char array name ‘charArray’ to the string constructor. Here’s the java program.

public class CharArrayToString
{
   public static void main(String[] args)
   {
      char[] charArray = new char[]{'F','l','o','w','e','r','B','r','a','c','k','e','t','s'};
      String str = new String(charArray);
      System.out.println(str);
   }
}

Output:

FlowerBrackets

Convert char array to string using valueof() method:

In valueOf() method of String class it returns string that contains the characters of the character array.

public class CharArrayToStringUsingValueOf
{
   public static void main(String[] args)
   {
      char[] charArray = new char[]{'F','l','o','w','e','r','B','r','a','c','k','e','t','s'};
      String str = String.valueOf(charArray);
      System.out.println(str);
   }
}

Output:

FlowerBrackets

Convert char array to string using StringBuilder: Here we iterate over characters and append each character to StringBuilder.

Finally we are calling toString() method on StringBuilder class. toString() method returns string representation of given sequence of characters.

public class CharArrayToStringUsingStringBuilder
{
   public static void main(String[] args)
   {
      char[] chArray = {'H', 'e', 'l', 'l', 'o', ' ', 'W', 'o', 'r', 'l', 'd'};
      StringBuilder sb = new StringBuilder();
      for(char ch: chArray)
      {
         sb.append(ch);
      }
      String str = sb.toString();
      System.out.println(str);
   }
}

Output:
