Hi,

Could anyone tell me is JDK6.0 can support all the java code worked in JDK1.3 ?

Thanks,

any Swing code written in 1.3 might have problems in 1.6 - the focus subsystem changed about 1.4

Generally, though, Java is backwards compatible - any code written and/or compiled using an earlier JDK will work on later JREs.

Although the behaviour may be slightly different, like the example Michael mentioned. Any workaround for a bug in Java 1.3 may now actually do something you don't want it to do.
