private void amethod(int iBase){
System.out.println("Base.amethod");
}
}

class Over extends Base{
public static void main(String argv[]){
Over o = new Over();
int iBase=0;
o.amethod(iBase);
}

public void amethod(int iOver){
System.out.println("Over.amethod");

v.i=30;
another(v,i);
System.out.print( v.i );
}//End of amethod

public void another(ValHold v, int i){
i=0;
v.i = 20;

Yes
if the start() method on a dead thread object
is invoked.

Exception will be throw is it Correct.

hi all

class test { static boolean m(double v) { System.out.println(v! = v); return(v != v == Double.isNaN(v)); } public static void main (String args[]) { double d1 = Double.NaN; double d2 = Double.POSITIVE_INFINITY; double d3 = Double.MAX_VALUE; System.out.println(m(d1) + "," + m(d2) + "," + m(d3)); } }
This code will compile & run fine

Result is true ,true,true

my doubt is

i can not understand return startment ( return(v != v == Double.isNaN(v)); )

anybody explain this line return(v != v == Double.isNaN(v))

Best & regards

hi Chris Allen

Thanks for ur help

bye

my question is

interface I1 {}
interface I2 {}
class Base implements I1 {}
class Sub extends Base implements I2 {}
class Orange {
public static void main(String args[]) {
Base base = new Base();
I1 i1 = base; // 1
Sub sub = (Sub)base; // 2
}}

Result is Run-time error at line 2

any one explain this question why runtime error come at 2 properly casting
is done .

why runtime error come?

Base base=null;
then casting it would come any runtime error .
why?

This is my question
class test {
public static void main (String[] args) {
char a = 061; // 1
char b = '\377'; // 2
System.out.print(""+a+b);
}}

this compiled fine but i will declar like that char b = '\378' it would not compile.

char b='\0' to char b='\377' this range work fine but after '\377' is not compile, Any body know help me
