Trying to set java compiler to compliance level to 5.0

Question

I'm trying to compile some facebook sample code in eclipse and it says I need compliance level 5.0 or 6.0. I tried to set the compliance level by:

1. right clicking on project name b. clicked on properties -> java compiler

on the drop down for compliance level, it had 1.3, 1.4, 1.5, 1.6 and 1.7 but did not have 5.0.

Answer 1

Java versioning is somewhat odd and annoying. 1.6 and 1.7 are well-known examples but generally you can get away with using 1.X for X . Here you'd use 1.5 .

Answer 2

The trick is that 5.0 is the same as 1.5. Since java 1.5, the names are denoted without a leading 1. source

Answer 3

Java 1.5 is 5.0. You can read about this here :

J2SE 5.0 (September 30, 2004)

Codename Tiger . Originally numbered 1.5, which is still used as the internal version number. This version was developed under JSR 176.
