don't use any IDE for SCJP

[jagan kay]

please dont use any IDE while preparing for SCJP. as of my experience the foll., prg., compiles & runs successfully in 'Eclipse editor'

abstract class Abs{
static int a;
static final int b;

static void displayB(){
System.out.println("Inside class 'Abs' & b="+b);
}
void displayA(){
System.out.println("Inside class 'Abs' & a="+a);
}
}
public class StatInAbsClsTest extends Abs{
public static void main(String... s){
System.out.println("Abs.a="+a);
System.out.println("Abs.b="+b);
//Abs obj=new StatInAbsClsTest();
//obj.displayA();
//displayB();
}
}
 
Output:
-------
Abs.a=0
Abs.b=0

when it's run on 'command prompt' the prg., doesn't compile. foll., error comes.

 
C:\Jagan\scjp_practise>javac StatInAbsClsTest.java
StatInAbsClsTest.java:1: variable b might not have been initialized
abstract class Abs{
         ^
1 error

that's what we need. matter of fact i'm preparing for SCJP & have been using Eclipse editor. now, going to use notepad & command prompt.

Java 1.6 Compiler is catching the Compile-time exceptions in my IDE

"Error(3,18): field b might not have been initialized"

I am using Oracle JDeveloper

[Marius Paraschiv]

Mine shows "The blank final field b may not have been initialized"

I have Eclipse 3.4 and JDK 1.5.0_15.

your right about not using eclipse for scjp work. I find netbeans ok though for non-classpath related work.
@jagan - you havn't stated what version of jre/eclipse your using, also check your jdk compiler compliance level

eclipse 3.3.1.1 & jdk 1.6.0_05 seems consistent in this situation

hi Frank Zito, sorry i forgot to mention it. mine is jdk 1.5 & Eclipse-SDK-3.3.2
Thanks to all.

If you're preparing for the SCJP, I think you're much better off working in an environment that doesn't instantly flag potential errors for you. You need to develop your own ability to look at the code and recognize what -- if anything -- might be wrong.

Eclipse has its own built-in Java compiler (based on IBM's Jikes compiler). Ofcourse that compiler is supposed to be 100% compatible with Sun's compiler from the JDK, but like any big and complicated piece of software Eclipse isn't completely bugfree.

I'm using Eclipse everyday, and it's rare, but I've encountered situations once or twice where the Eclipse compiler would give an error while the JDK compiler would not or the other way around.

For preparing for SCJP, it's best to use Sun's compiler from the JDK.
