There is a current project which has many lines of code and written for Java 6-7. I want to migrate it to Java 8 and use lambda expressions wherever I can.

How can i scan the project and report that an expression can be replaced with a lambda equivalent?

    Why would you do that blindly? Lambda expressions are not a silver bullet; you use them only when they are the right tool for the job.

  • I want to report them by a tool and replace it via lambda equivalent if it will result with a performance increase. I don't search for a tool which will automatically replace such code blocks.

    I doubt that you would see any performance increase by merely converting things to lambda expressions. That said, the tool you're looking for is probably IntelliJ IDEA.

  • You will not be just replacing things, you will have to do extensive refactoring. I guess.

  • Yes, it will be a refactoring process. @RobertHarvey I know that lambdas are slower than the conventional loops etc. but you can get a performance increase if you use them when to use i.e. piping or parallel streaming.
