GCC checked out on 2005-01-03 compiles the following code without
complaint, using the command line "gcj -C -Wall -W -pedantic
ArrayLength.java":
class ArrayLength {
static int extend(int[] array) {
/* array.length = 1; */
array.length++;
return array.length;
}
}
It generates the following bytecode for the method:
0: aload_0
1: dup
2: getfield <Field [I.length int>
5: iconst_1
6: iadd
7: putfield <Field [I.length int>
10: aload_0
11: arraylength
12: ireturn
However, if I uncomment the first assignment, I get this error:
ArrayLength.java: In class 'ArrayLength':
ArrayLength.java: In method 'ArrayLength.extend(int[])':
ArrayLength.java:3: error: Can't reassign a value to the final variable 'length'.
array.length = 1;
^
1 error
I think it is inconsistent to allow ++ if the field is final.
