[Output will be not equal
bcoz when u use any method of string class , it's creates new string object and hence trim()will creat new string and hence results false condition
rahul
public class ObChk
{
public static void main(String[] args)
{
Ex e1=new Ex(1,2);
Ex e2=new Ex(1,2);
Ex e3=new Ex(4,5);
Ex e4;
e4=e2;
if (e1.equals(e2))
{
System.out.println("e1 and e2 Equal");
}

if (e1.equals(e3))
{
System.out.println("e1 and e3 Equal");
}
if (e2.equals(e4))
{
System.out.println("e2 and e4 Equal");
}
}
}

The above program outputs only
e2 and e4 are equal.
can u tell me y ?
thanks

hi friends ,
i am confused with the statements.
in jls it is mentioned that decimal integer or factorial values give compile time error if the value is greater than the range
of data type but then
how come following program get compile without error
public class test {
public static void main(String args[])
{
int i = 1000000 ;
System.out.println(i*i);//here result is 1000000000000 which
which is out of integer range
}
}

class Q81{
public static void main(
String args[]){
System.out.print(
Double.isNaN(3.0%0));
System.out.print(" ");
System.out.println(
Double.isNaN(3.0/0));
}//end main()
}//end class definition
what is the output of above program and y ?
thanks

hi fernando ,
i think sub3 should be legal .
sub4 is correct and sub5 is also legal .
bcoz as per rule overriding method can throw exceptions , those r thrown by overridden method or can throw exceptions those r subclass of the exception thrown by overridden method .this is true only for checked exceptions .
so as per rule sub4 is throwing an exception which is base class exception of amethod()which is illegal and sub5 is throwing an exception which is subclass of ioexception so legal .
only doubt is about sub3
actually sub3 should work .
so please check that out again .
bye rahul
