unreachable statement

[Parameswaran Thangavel]

hi

why the compiler thrown unreachable error

how the true or false in while loop influence the unreachable statement at (1) and (2)


class Test
{

public static void main (String args[])
{
int i=1;
do

while(false) //always true
System.out.println( "Ok" ) ;//unreachable statement (1)
while( i < 1 );

System.out.println("hai");
}
}



class Test
{

public static void main (String args[])
{
int i=1;
do

while(true) // true
System.out.println( "Ok" ) ;
while( i < 1 );

System.out.println("hai");//unreachable statement (2)
}
}

hi Parameswaran

the statement System.out.println("hai");//unreachable statement (2) is unreachable because the while loop is infinite.
you have written while(true)!! it will never get out of that loop..

thus the last line

"System.out.println("hai");//unreachable statement (2)"

is unreachable.
