Q)What is the output of the following piece of code?
int a=10;
a *=3;//compound assignment
System.out.println(a);

Ans:- 30

Q)What is the output of the following piece of code?
int a=10,b;
b=++a;//pre-incrementation
System.out.println(b);

Ans:- 11

Q)What is the output of the following piece of code?
int a=10,b;
b=a++;//post-incrementation
System.out.println(b);

Ans:- 10

Q)Explain about relational operators.
=>relational operators are also known as comarision operators.
=>They are used to compare two values and return a boolean value.
=>As they act upon two operands, they are binary operators.
=>The following are the relational operators.

==(equality operator)
!=(inequality operator)
>
>=
<
<=

Q)What is the output of the following piece of code?
int a=10,b=20;
System.out.println(a==b);

Ans:- false

Q)What is the output of the following piece of code?
int a=10,b=20;
System.out.println(a!=b);

Ans:-true


Q)What is the output of the following piece of code?
int a=10,b=10;
System.out.println(a<=b);

Ans:- true
Q)Explain about logical operators.
=>There are 3 logical operators.
     1)&&(logical and operator)
     2)|| (logical or operator)
     3)! (logical not operator)

Q)Explain about "logical and" operator.
     =>It is a binary operator
    =>It is  used to combine two relational expressions
   =>It acts upon 2 operands and returns a boolean value.
   =>It returns true if and only if both the operands are true.
                                  Result
           T   &&   F           F
	   F   &&   T           F
	   F &&    F            F
	   T  &&  T             T


Q)What is the output of the following piece of code?
int a=10,b=20,c=40;
System.out.println(a>b && b<c);

Ans:-  F

Q)Explain about "logical or" operator.
 =>It is a binary operator
 ||  is the logical or oeprator
 =>It is  used to combine two relational expressions
 =>It acts upon 2 operands and returns a boolean value.
   =>It returns true if atleast one operand is true.
                                  Result
           T   ||   F             T
	   F   ||   T             T
	   F  ||    F             F
	   T  ||  T               T
                                
Q)What is the output of the following piece of code?
int a=10,b=20,c=40;
System.out.println(a>b || b<c);

Ans:- true

Q)Explain about logical not operator.
=>It is a unary operator
=>It acts upon a boolean expression and complements it.
Q)What is the output of the following piece of code?
int a=10,b=20,c=40;
System.out.println(!(a>b  || b<c));

Ans:- false
                  FLOW CONTROL STATEMENTS
	          ---------------------------------
Q)What features should an application posses to solve a computing problem?
     1)sequence
     2)selection
     3)iteration(repetetion)
=>sequence is the  feature of a program by which, its code is executed sequentially
line by line(line after the line).
Note:- By default, every Java program has sequence feature.
Q)What is "selection" feature?
=>selection is the ability of a program to select some portion of code for execution
when some condition is satisfied.

Note:- selection feature is not implicit(automatic) in a Java program

Q)What is repetetion?
=>repetetion is the ability of a program to execute some portion of code repeatedly.

Note:- repetetion feature is not implicit(automatic) in a Java program
Q)What is a flow control statement?How are flow control statements classified?

=>A statement that controls the order of execution of the other statements of
the program is nothing but a flow control statement.

=>There are two types of flow control statements in Java.
     1)Selection statements/branching statements
     2)iteration statements/repetetion statements/looping statements

Q)What are the branching statements in Java?
=>There are 5 branching(selection/decision making) statements in Java.

         1)simple if statement
	 2)if else statement
	 3)if else ladder statement
	 4)nested if  statement
	 5)switch statement

Note:- These statements provide "selection" feature to Java application.

Q)What are the iteration statements in Java?
        1)for statement
	2)enhanced for statement(for each statement)
	2)while statement
	3)do while statement
