The document discusses conditional statements in Java programming. It describes if-else, if-else-if-else statements and nested conditional statements. It also covers relational operators like ==, !=, <, <=, >, >= and logical operators like &&, ||, ! that are used to evaluate conditions. Examples are provided to demonstrate how to use if, if-else, if-else-if-else statements to run certain code blocks based on conditional expressions. The equals function is also introduced to compare string values more efficiently.

1. Java Programming
Conditional Statements IF-ELSE-ELSE-IF

2. Objectives
 Conditional Statements
 Relational Operators
 IF Statements
 IF - ELSE Statements
 IF - ELSE IF – ELSE Statements
 Nested Conditional Statements
 Equals Function
 Logical Operators
 Grade Average Program

3. Conditional Statements
Allows a program to take action based
on the given condition. It makes our
program smarter.

4. Conditional Statements
Typically, It compares two values so
that our program can decide what
action should be taken.

5. Relational Operators
LABEL SYMBOL SYNTAX
Equals == X == y
NOT Equals != X != y
Less Than < x < y
Less Than or Equals <= X <= y
Greater Than > X > y
Greater Than or
Equals
>= X >= y

6. IF Statement
Handles 1 Conditional Expression, It
either does SOMETHING or NOTHING.

7. IF Statement
If(condition) {
//Do Everything you want here
}

8. IF Statement
If(age >= 18) {
System.out.println(“You Have Access!”);
}

9. IF – ELSE Statement
Handles 2 Conditional Expressions, It either
does the first Code Block or the second Code
Block.

10. IF – ELSE Statement
If(condition) {
//Do Everything you want here
}else{
//Do Everything you want Here
}

11. IF – ELSE Statement
If(age >= 18) {
System.out.println(“You Have Access!”);
}else{
System.out.println(“Access Denied!”);
}

12. IF – ELSE IF – ELSE Statement
Handles 3 or More Conditional Expressions,
The possibility of this Statements are limitless it will
run a certain code block based on the condition

13. IF – ELSE IF – ELSE Statement
If(condition) {
//Do Everything you want Here
}else if(condition) {
//Do Everything you want Here
}else {
//Do Everything you want Here
}

14. IF – ELSE IF – ELSE Statement
If(age >= 18) {
System.out.println(“You Have Access!”);
}else if(age >= 13) {
System.out.println(“You Need Parent
Consent!”);
}else {
System.out.println(“Access Denied!”);
}

15. NESTED Conditional Statement
A Conditional Statement within a Conditional
Statement.
PS: The Nested Conditional Statement can be
any Type of Conditional Statement.

16. NESTED Conditional Statement
if(condition) {
if(condition) {
//Do Anything You Want Here
}
}

17. NESTED Conditional Statement
If(age >= 18) {
if(isVerified) {
System.out.println(“Qualified”);
}
}

18. Equals Function
To compare Strings more efficiently we
need to make use of the Equals Function
because the Equal relational operators
compares the memory address not the
Content.

19. Equals Function
String x = “Hello”;
If(x.equals(“Hello”)) {
System.out.println(“Hi”);
}
