Hi Somw help to get the answers for these Questions

Question

Q1 Which one of the following is NOT polymorphic behavior?
a.     Method overloading -- having methods with the same name but different signatures
b.     Implicit type conversion -- for instance, a java.util.List class converts its members to Objects
c.     Explicit type conversion -- when a class is converted to another class by a class cast statement
d.     Method inheritance -- when a subclass inherits the behavior of the class from which it inherits
e.     Using interfaces -- where any class can implement an interface for a given behavior, e.g. Runnable
Q2 The following code defines the Example class.
package com.brainbench.javaexamples;
public class Example {
public static final int VALUE = 10;
// Additional code not shown.
Referring to the sample code above, what classes modify the value of Example.VALUE
a Inner classes of Example only
b Classes in the same package only
c Classes in the same source code unit only
d. Classes in Java standard packages only
e. None of the classes
Q3 What is a classpath?
a.     A search path for loading class files from disk
b.     It exports Java code remotely
c.     It protects the multiple JVMs from interfering with each other
d.     It specifies which Java files must be compiled.
e.     The security behavior of java.security
Q4 Which one of the following is NOT a configurable JVM option?
a.     Collect profiling and debugging statistics.
b.     Set the maximum memory allocation pool size.
c.     Set the initial memory allocation pool size.
d.     Modify the garbage collector's behavior
e.     Modify the number of bits a double variable uses.
Q5 a. public void foo() {..}
b. void foo() {..}
c. protected void foo() {..}
d. private void foo() {..}
e public final void foo() {..}
Which of the methods above are overridden via inheritance?
a.     a and c
b.     a and e
c.     a, b and c
d.     a, b and d
e.     c, d and e

a.     Method overloading -- having methods with the same
name but different signatures
b.     Implicit type conversion -- for instance, a
java.util.List class converts its members to Objects
c.     Explicit type conversion -- when a class is

d.     Method inheritance -- when a subclass inherits the
behavior of the class from which it inherits
e.     Using interfaces -- where any class can implement

_________I would say c) beacause you need to state it clearly to the compiler, so it is not this great automatic polymorphic java behaviour.

Q2 The following code defines the Example class.
package
com.brainbench.javaexamples;
public class Example {
public static final int VALUE = 10;
// Additional code not shown.

classes modify the value of Example.VALUE
a Inner classes of Example only
b Classes in the same package only
c Classes in the same source code unit only
d. Classes in Java standard packages only
e. None of the classes
___I would say e) beacause this variable is final which means you can't change it once initialized.

a.     A search path for loading class files from disk
b.     It exports Java code remotely
c.     It protects the multiple JVMs from interfering
with each other
d.     It specifies which Java files must be compiled.
e.     The security behavior of java.security
________a). Using classpath class loader load the classes.

a.     Collect profiling and debugging statistics.
b.     Set the maximum memory allocation pool size.
c.     Set the initial memory allocation pool size.
d.     Modify the garbage collector's behavior
e.     Modify the number of bits a double variable uses.
_______I would say e) because in Java every primitive value (including double) has the same size on every platform. Thats one thing why Java is portable.

c. protected void foo() {..}
d. private void foo() {..}
e public final void foo() {..}
Which of the methods above are overridden via
inheritance?
a.     a and c
b.     a and e
c.     a, b and c
d.     a, b and d
e.     c, d and eI would say b) but I think the order is also important which is not stated in this question ( c) would be also good if methods in reverse order - c -> b -> a ) a) not because you can't reduce the visibility of a method. And two others includes private method, which doesn't take part in inhertiance at all (it is invisible when inheritted so can't be overriden, or you can't reduce visibility to private).
