How to use this tool?

This free online converter lets you convert code from Java to Scala in a click of a button. To use this converter, take the following steps -

  1. Type or paste your Java code in the input box.
  2. Click the convert button.
  3. The resulting Scala code from the conversion will be displayed in the output box.

Examples

The following are examples of code conversion from Java to Scala using this converter. Note that you may not always get the same code since it is generated by an AI language model which is not 100% deterministic and gets updated from time to time.

Example 1 - Is String Palindrome

Program that checks if a string is a palindrome or not.
