which method is used to force calling class destructer?

define an integer instance that has a class access

how would you prevent a class from being used as a base class?

given the following :
string si="hi";
string s2="his";
string s3=s2;
s2=null;
s2=s1;
what is printed by the following?
system.out.println(s2+s3+s1+(s2==s1));

correct the following code segment :
public interface looney
{
public abstract void add();

void compute()
{
system.out.println("\nthis is it");
}
}

You are now going to write the printSign() method. Your method must: use the public access modifier
take a single formal argument of type double
return no value, i.e. have a void return type
use the divide() method to find the result of attempting to divide the argument by the current value of divisor and store the result in a suitable local variable called quotient
l using nested selection statements, print out to the Display Pane 'The quotient is zero', 'The quotient is positive', or 'The quotient is negative', depending on whether quotient is zero, greater than zero, or less than zero, , respectively.
Write the method printSign() as specified above. You should include an appropriate comment before the method header describing what the method does in terms of its argument and the output in the Display Pane.
