As the spec states, initialization does not apply to local variables. You
have the relevant text
in your quote of the spec:
"A local variable (�14.3, �14.12) must be explicitly given a value before it
is used, by either initialization (�14.3) or assignment (�15.25), in a way
that can be verified by the compiler using the rules for definite
assignment"
Just add two lines to your example main and it will not compile because a
local variable has
no intial value.
class Point {
static int npoints;
int x, y;
Point root;
}
public class Test {
public static void main(String[] args) {
Object localVar;
System.out.println("localVar=" + localVar);
System.out.println("npoints=" + Point.npoints);
Point p = new Point();
System.out.println("p.x=" + p.x + ", p.y=" + p.y);
System.out.println("p.root=" + p.root);
}
}
bash-2.02$ javac Test.java
Test.java:10: Variable localVar may not have been initialized.
System.out.println("localVar=" + localVar);
^
1 error
