Module 2_If,Else,Else if

IF,else and If else program

01.What is if condition?
Only if the condition is true.

if conditional syntax:
if()
{
}

02.What is else statement?
Used with if to run an alternative block if the condition is false.

else conditional syntax:
else
{
}

03.What is if else condition?
if...else is the full structure that checks a condition and handles both true and false cases.
You can think of if...else as a decision-making tool:
if: do something if true
else: do something else if false.

if else syntax:
if else()
{
}

04.What is else if condition?
Checks additional conditions.

Example:

public class ATM Withdrawal {

public static void main(String[] args) {


    int balance = 10000;

    int amount = 5000;

    // If statement
    if(amount <= 0)//false
    {
        System.out.println("Invalid amount, Please enter an amount grater than zero");
    }

    //else if statement
    else if(amount > balance)//false
    {
        System.out.println("Insufficient balance");
    }
    // else statement
    else {
        System.out.println("Collect your cash " + amount);
    }

}

amount == statement (True or false statement)

int amount = 20000;
if(amount != 30000)
{
System.out.println("True"+ amount);
}
else
{
System.out.println("Not Equal");
}

if condition (True)statement
if(true)
{
System.out.println("Collect your cash" + amount);
}
else
{
System.out.println("Fail");//Dead code
}

if condition (False)statement
if(false)
{
System.out.println("Collect your cash" + amount);//Dead code
}
else
{
System.out.println("Fail");
}
