There are multiple ways to convert a character array (char[]) to a string in Java. You can use the string constructor, the String.valueOf() method and Streams API to convert a sequence of characters to a string object.
Convert char[] to a string using the String constructor
The easiest way to convert a character array to a string is using the string constructor e.g. new String(char[]).
The String class in Java provides an overloaded constructor that accepts a char array as an argument. Here is an example:
// Declare char array
char[] chars = {'M', 'a', 'n', 'g', 'o'};
// Convert the char array to a string
String str = new String(chars);
System.out.println(str);
// Mango
Convert char[] to a string using String.valueOf()
The String.valueOf() method is yet another simple way to convert a char[] to a string in Java. It returns the string representation of the passed argument, as shown below:
// Declare char array
char[] chars = {'M', 'a', 'n', 'g', 'o'};
// Convert the char array to a string
String str = String.valueOf(chars);
System.out.println(str);
// Mango
Convert char[] to a string using Arrays.stream()
Java 8 provides the Arrays.stream() method to create a stream using an array of characters. Then, you can use the Collectors.joining() method to convert the stream into a string object:
// Declare char array
Character[] chars = {'M', 'a', 'n', 'g', 'o'};
// Convert the char array to a string
String str = Arrays.stream(chars)
.map(String::valueOf)
.collect(Collectors.joining());
System.out.println(str);
// Mango
