Is there a way to create custom warning in eclipse?

Question

I know that the obvious answer is "pay attention" but because I am constantly switching between Java and Javascript, I'm endlessly forgetting that == doesn't work for string comparison on the Java side of things. Is there any way to get Eclipse to warn me that I'm probably not doing what I want to be doing when it sees me comparing two strings with == rather than using the equals() method?

Answer 1

There are many static code analyzer available which does such type of things. Few of them are:

1. checkStyle
2. PMD
3. sonar
4. findBugs

They have many in-built rules and you can configure them in eclipse also. So as and when, you type and save, these tools would also show warnings just like in-built eclipse warnings.
