Converting a Char Array to a String

In Java, converting a char array back to a string can be achieved using the String constructor. The following code illustrates how to perform this conversion:

char[] a = {'h', 'e', 'l', 'l', 'o', ' ', 'w', 'o', 'r', 'l', 'd'};
String b = new String(a);

This solution is effective and straightforward, as it directly converts the char array into a string. It is also the recommended approach in Java.

Alternatively, one could manually concatenate the characters in the array to form a string. However, this method is inefficient and more prone to errors. It is not recommended for converting char arrays to strings in Java.
