Common questions
Frequently Asked Questions
How do I convert Delphi to Java?
Paste your Delphi code into the input box, confirm the languages are set to Delphi and Java, and click Convert. CodeConvert AI analyzes your Delphi code and generates equivalent Java code in seconds, preserving the original logic and structure.
What are the main differences between Delphi and Java?
Delphi and Java differ in syntax, type system, standard libraries, and common idioms, so copying code line for line usually will not compile. The converter maps each Delphi construct to its closest Java equivalent. See the comparison table below for the key differences between Delphi and Java.
Is the converted Java code accurate?
The AI produces high-quality Java code that preserves the behavior of your original Delphi code and follows Java conventions. It handles common patterns, data structures, and idioms for both Delphi and Java. For large or performance-critical code, review and test the Java output before using it in production.
Can I convert an entire Delphi project to Java?
You can convert Delphi files one at a time by pasting each file's code. For a full migration, convert each file and then review how classes, dependencies, and project structure map from Delphi to Java. Signing in for free raises the input limit to 25,000 characters per conversion for larger files.
