Java Keywords

This is the correct answer. If a data member is made transient, it will not be serialized.

The keyword extends is used to implement the inheritance in Java.

Both the given statements are true that is the super keyword is used to access the constructor of superclass and variable from the subclass.

Interface can be implemented using the implements keyword because definition is not allowed within the interface. So, it has to be implemented.

This is the correct answer.  The static keyword is used to  declare a variable class level.  For example, counters are made class level so that different class objects can access the same variable and perform actions on it.

All the variables within the interface must be final and initialized within the interface.

There is no such keyword as virtual in Java. 

The protected access specifier works as private for outside world, but works as public for derived classes in Java.

If the first statement of a constructor has the form this(parameter list), then the constructor calls another constructor of the same class. For example:
class Emp
{
    int m;
    double n;
    public Emp(int x)
    {
            this(789.89,x);
     }
}
Here, this(789.89,x) statement calls the constructor Emp(double,int)

The protected access specifier is very useful in multilevel inheritance because the protected member of super class A can be accessed by the subclass C in the following way.
A(Super Class)$\rightarrow$ B(Subclass of A) $\rightarrow$C(Subclass of B)

This is a false statement. There can only be one finally block for each try block. Since the statement is false about 'finally' block in Java, it is the correct alternative.
