Private(Class Access) Public(Global Access) Default(Package Level Access) Protected(Inside the same Package and in the outside package we can access but based on only inhertance relationship )

3.  Final
 Synchronized
 Abstract
 static

4.  The final keyword prevents a method from being overridden
in a subclass
class SuperClass{
public final void showSample()
{
System.out.println("One thing.");
}
}
class SubClass extends SuperClass{
public void showSample()
{
// Try to override the final
// superclass method
System.out.println("Another thing.");
}
}

5. class Bank
{
int accountBalance ;
public Bank(){
accountbalance = 10000;
}
Synchronized void BalanceInquiry(){
System.out.println(“account
balance is :”+accountbalance);
}
}

6. abstract class Hotel
{
public void Idli(){
System.out.println(“Prepare Idli”);
}
abstract public void Dosa();
}

7. class Pageview
{
public static final int count = 0;
public Pageview()
{
count++;
System.out.println(“Number of views
to website”+count);
}
public static void main(String args[])
{
Pageview p = new Pageview();
}
}

8.  Arithmetic Operators
 Relational Operators
 Bitwise Operators
 Logical Operators
 Assignment Operators

16.  Bitwise operator works on bits and performs bit-by-bit operation. Assume
if a = 60; and b = 13; now in binary format they will be as follows:
 a = 0011 1100
 b = 0000 1101
 ------------------------------------------------------------------------------------------
 a & b = 0000 1100
 a || b = 0011 1101
 a ^ b = 0011 0001
 ~a = 1100 0011

25.  Conditional Operators are also called ternary
operator
 This operator consists of three operands.
 It is used to evaluate an expressions
 Syntax:
variable x = (expression) ? value if true : value if
false

26. public class Test{
public static void main(String args[])
{
int a, b;
a = 10;
b = 20;
( a > b ) ? a : b ;
( a <10 ) ? a : b ;
}
}

27.  Methods declared public in a superclass also must be public in
all subclasses.
 Methods declared protected in a superclass must either be
protected or public in subclasses; they cannot be private.
 Methods declared without access control (no modifier was
used) can be declared more private in subclasses.
 Methods declared private are not inherited at all, so there is no
rule for them.
