HI,
can u anybody explain what is the drawback of "new" key word?
Let me know
String s ="hello";
In this statement The reference s wherer it is sorted? that means stack,heap or StringPool
String s = new String("hello");
in this statement the reference 's' where it is stored?
Let me know
GC
I have a code

class C13
{
public static void main(String[] args)
{
C13 c1 = new C13();
C13 c2 = m(c1);
C13 c3 = new C13();
c2 = c3; // line 1

// here code is there
}
static C13 m(C13 obj)
{
obj = new C13();
return obj;
}
}
After line 1 how many obj are eligible to GC ?
Can You please explain ?
I have a code

class Int
{
public static void main(String[] args)
{
a(Integer.MAX_VALUE , Integer.MAX_VALUE);
}
staticvoid a(double a , float b)
{
if( a == b)
System.out.println("equal");
else
System.out.println("not equal");
}
}

This is gives "not equal"

This is only for Integer.
But if you use Byte,Short, Long, Float it gives "equal"
Let me know what is the behind reason
String s ="hai";

In this line how many objects are created?
I think 2 obj, one is 's' and another is 'hai'


String s = String("hai");

and this statement also 2 obj are created
Let me know am i right or not?
I have a pice of code:

class StringExample
{
public static void main(String[] args)
{
String s ="Hello";
String t = s.toLowerCase();
String u = s.toLowerCase();
if( t == u)
System.out.println("equals");
else
System.out.println("false");
}
}
In this code string obj 't' and 'u' are created using 's' obj
but it prints false
i can't under stand why like that?
I think toLowerCase() gives every time a new obj? am i right?
let me know?
if you send -ve parameter in abs() it gives +ve value
but
Math.abs(Integer.MIN_VALUE) & Math.abs(Long.MIN_VALUE)
gives -ve value
i don't how it is given like that

Can u plz explain?
Class A
{
public static void main(String [] args){
String s = null;


}
}


In this statement Object 's' is created or eligible for garbage collection?
