Eclipse : Java Compliance Level 5.0

what is the significance of Java Compliance Level : 1.5/5.0 in eclipse ?

What if i set this to 1.5 and not 5.0 ?

thanks in advance....

Same result. 5.0 is a synonym of 1.5.

I think, you didn't understand my question. i'm asking why the compiler throughs error sometimes if i use generics, etc if i do not switched to 5.0 from 1.5 in eclipse?
Is there anything related to JDK ?

If the Compiler Compliance Level is not at 1.5 or later, then 1.5-level features get flagged as errors. And for me the Compiler Compliance Level drop-down offers the choices of 1.6, 1.5, 1.4, and 1.3 (5.0 is not an option). So where are you seeing the 5.0?

What version of Eclipse are you running?

thanks for your response but there are other options such as 5.0, 6.0 etc. See the atachment for more understanding.

Which version of Eclipse are you running? I looked in 3.5 and 3.6 and in both the compiler compliance levels are 1.3, 1.4, 1.5 and 1.6.

its eclipse 3.2 version

That would explain it. You might consider upgrading to a more recent version of Eclipse.
