The document discusses basic operators, loops, and control statements in Java. It covers arithmetic, relational, logical, bitwise, and assignment operators. The core loops covered are for, while, and do-while loops, including their syntax and usage. Break and continue statements are also discussed, explaining how break exits the current block/loop and continue skips to the next iteration. The document provides examples of each concept and proposes programming tasks to demonstrate understanding.

1. Basic Operators and Loop
Control in Java.
•Arithmetic Operators?.
•Logical Operators?.
•Relational Operators?.
•Bit wise Operators?.
•Assignment Operators?.
•For, while, do whole loop in java?
•Break and Continue Statements?

2. Basic Operators
• Arithmetic Operators: These are same which are
used in mathematical expressions.
• These are (+,-,*,/,%,++,--).
• Relational Operators: These are used to relate
expressions methomatically
• These are (==, >=, <=, >, <, !=) used in java.
• Bitwise Operator: Operations performed on bits
• These are (&’bitwise AND’, II’or’, ^’XOR’,
<<‘LEFTSHIFT’, >>’rightshift’, >>>’zeroshift’ ).

3. Basic Operators.
• Logical Operators: These are used when
there are two condition in a statement.
• These are (&&, II, !).
• Assignment Operators: These are operators
which are used to assign the values.
• These are(=,=+, -=, *=, /=, %=,<<=, >>=)

4. Write a program to demonstrate all
basic operators in java.

5. Program Cont…
• Guess the output of the above program.
• Note: Write a program to use all the types of
each basic operator.

6. Loops
• Loops are used to execute a code of block for several times.
• A loop Consists of a conditional code and a condition.
• The code of block will run till the condition is true.
There are three loops in java.
If true
else

Condition Execute
Code

7. 1. While Loop
• Continues or execute the code till the condition
is true.
• Tests condition before executing the code.
• Syntax: while(condition){}
• E.g: int a=4, b=11;
while(b<12){
System.out.println(“output=”+(a+b));
}

8. While Syntax
While(bool exp)
if true
else
4/10/2019 Jamsher Bhanbhro(F16CS11) 8
Condition
Boolean
Expression
Execute
Code

9. 2. For Loop
• Executes the code multiple times
• Approximately same as while but there is some
difference.
• In this loop we will give initialization, condition
and increment values.
• for(init, cond, update){code body}
e.g: int a=11;
for(int i=0; i<=a; i++){
System.out.println(“Hello”);
}

10. For Syntax
While(bool exp)
if true
else incr
4/10/2019 Jamsher Bhanbhro(F16CS11) 10
Condition
Boolean
Expression
Execute
Code
Update
Cond

11. 3. Do While Loop
• Same as while loop but..
• Executes at least once without checking
condition.
• do{}while(cond)
int a=1, b=3;
do{
System.out.println(a*b);
}while(a!=b)

12. 3. Do Syntax
While(bool exp)
if true
else

Condition
Boolean
Expression
Execute
Code

13. Why Loops are used write the
advantages.
• Loops are used to reduce the code.
• Loops provide flexibility to the code.
• Loops are highly used in the programming
specially when we are related with arrays.
• Although it is very important to remember the
syntax and the phenomenon of the loops
structures.

14. Break and Continue Statements
• When the break statement is encountered inside a
loop.
• It breaks the statement and gives the current flow
to the next level.
• Switch() in the cases this break is used.
Eg: int a=11;
if(a>10){
break;
}

15. Continue Statement
• Continue statement is used when we want to continue our
block of code.
• Used for jumping purpose.
• In the for loop continue is used to jump to update statement.
• In while continue used to jump to a Boolean expression.
• Syntax: continue;
int a=15;
if(a>11){
continue;
}

16. Tasks
Write a program to draw shape of
• Triangle
• Rectangle
• Pyramid
• Diamond
• Write a program to make a simple calculator of
at least six functions using break and continue
statement.
