How to Convert a Char Array to a String in Java: Best Practices and Alternative Methods

Conversions Between Char Arrays and Strings in Java

When dealing with char arrays and strings, developers often face scenarios where conversion between these data types is required. This article explores the best practices for converting a char array back to a string in Java.

Current Solution

A common approach is to utilize the String constructor that takes a char array as an argument:

String b = new String(a);
Copy after login

This solution is efficient and straightforward, resolving the conversion issue.

Alternative Methods

The provided solution is widely recognized as the most effective means of converting a char array to a string. However, there are additional methods that can be considered:

1. Using the String.valueOf() Method:

String b = String.valueOf(a);
Copy after login

2. Using the Apache Commons Lang Library:

<code class="java">import org.apache.commons.lang3.ArrayUtils;
String b = ArrayUtils.toString(a);</code>
Copy after login

Best Practice

While alternative methods exist, the direct conversion using new String(a) is considered the most efficient and idiomatic approach in Java. Other methods may be useful in specific use cases or when working with third-party libraries, but for general purpose conversion, new String(a) is the recommended choice.

Additional Notes

It's important to note that handling strings in Java differs significantly from C/C due to special handling of strings in the Java Virtual Machine. Consequently, scenarios where character arrays need to be split or joined are uncommon in normal Java code.
