That being said, Java code can be converted to Kotlin from within Android Studio using a built-in Java to Kotlin converter. To convert an entire Java source file to Kotlin, load the file into the Android Studio code editor and select the Code -&amp;gt; Convert Java File to Kotlin File menu option. Alternatively, blocks of Java code may be converted to Kotlin by cutting the code and pasting it into an existing Kotlin file within the Android Studio code editor. Note when performing Java to Kotlin conversions that the Java code will not always convert to the best possible Kotlin code and that time should be taken to review and tidy up the code after conversion.&lt;/div&gt;&lt;/td&gt;&lt;td class=&#039;diff-marker&#039;&gt;&amp;#160;&lt;/td&gt;&lt;td style=&quot;background-color: #f9f9f9; color: #333333; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #e6e6e6; vertical-align: top; white-space: pre-wrap;&quot;&gt;&lt;div&gt;Given the high level of interoperability between Kotlin and Java it is not essential to convert existing Java code to Kotlin since these two languages will comfortably co-exist within the same project.
