Hi Saket
Must we return a value in native ? can native be final/protected ?
Can it be declared in abstract or interface ?

must we implement all abstract methods in a subclass ?
whats the difference btn the above ?

Ordered sometimes - mean the order which the element are being inserted into the List/Set
and it will be output depending on the sequence of the collection

what abt a+b ?

Hi

I am looking for all native declaration(legal) and where in a Java class can you place the native code .
Includind inner class, methods , etc.

Given the following class, which are correct implementations of the hashCode() method?
class ValuePair {
public int a, b;
public boolean equals(Object other) {
try {
ValuePair o = (ValuePair) other;
return (a == o.a && b == o.b)
|| (a == o.b && b == o.a);
} catch (ClassCastException cce) {
return false;
}
}
public int hashCode() {
// Provide implementation here.
}
}

i think i got it , thks Anupamm

oops sorry anu, just make it i =....

why error in the line after 12:
public static void main(String[] args) {
int counter = 0;
l1:
for (int i=0; i<10; i++) {
l2:
int j = 0;
while (j++ < 10) {
if (j > i) break l2;
if (j == i) {
counter++;
continue l1;
}
}
}
System.out.println(counter);
}
}

can somebody explain ? thks
public class Qf1e3 {
String s1;
String s2 = "hello";
String s3;
Qf1e3() {
s1 = "hello";
}
public static void main(String[] args) {
(new Qf1e3()).f();
}
{
s3 = "hello";
}
void f() {
String s4 = "hello";
String s5 = new String("hello");
assert(s1.equals(s2)); // (1)
assert(s2.equals(s3)); // (2)
assert(s3 == s4); // (3)
assert(s4 == s5); // (4)
}
}
