Java Conditional Statements Quiz

Conditional Statements

• Conditional statements allow programs to take actions based on given conditions, making them "smarter"
• They typically compare two values to decide which action to take

Relational Operators

• Relational operators compare values in conditional statements using symbols like == (equals), != (not equals), < (less than), > (greater than), <= (less than or equal to), and >= (greater than or equal to)

IF Statements

• Handle one conditional expression
• They execute a code block if the condition is true, otherwise, no action is taken
• Example:

if (age >= 18) {
   System.out.println("You Have Access!"); 
}

IF-ELSE Statements

• Handle two conditional expressions
• Execute the first code block if the condition is true, else execute the second code block
• Example:

if (age >= 18) {
   System.out.println("You have Access!");
} else {
   System.out.println("Access Denied!") ;
}

IF-ELSE IF-ELSE Statements

• Handle three or more conditional expressions
• The program runs one specific code block depending on the condition that evaluates to true
• Example:

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!"); 
}

NESTED Conditional Statement

• A conditional statement within another conditional statement
• The nested statement can be any type of conditional statement
• Example:

if (age >= 18) {
    if (isVerified) {
       System.out.println("Qualified");
    }
}

Equals Function

• Used to compare strings more effectively
• Compares the content of strings, not their memory address
• Example:

String x = "Hello";
if (x.equals("Hello")) {
  System.out.println("Hi"); 
}

Logical Operators

• Combine multiple conditional expressions
• && (AND): Both conditions must be true
• || (OR): At least one condition must be true
• ! (NOT): Inverts the given condition

Grade Average Program

• Takes four user input grades for different subjects
• Calculates the average of the grades
• Prints a message based on the average grade:
  • Above 100 – Invalid Grade
  • 98 to 100 – With Highest Honors
  • 95 to 97.99 – With High Honors
  • 90 to 94.99 – With Honors
  • 75 to 89.99 – Passed
  • Below 75 - Failed
