exceptions

[ramya kandasamy]

can we say all compile time error messges are build in exceptions in java software

[jkmyoung]

Probably not. Some Java compilers are not be written in Java. Even if they are, the compiler may use something other than exceptions as a way of storing the compile time errors.

[ramya kandasamy]

which is the platform used for java development? and do we hava different compilers for different operating systems?

[jkmyoung]

1. I suggest googling "Java Platform". Java SE should fulfill most needs.

2. ...Not really a straight answer: Java compiles it's code into a code readable by a Java Runtime Engine (JRE), which executes the code.

JRE's are different for different platforms. So this makes your Java application portable.
