Salesforce If else Statements
If else Statements
If else statements are used to control the conditional statement that are based on various conditions. It is used to execute the statement code block if the expression is true. Otherwise, it executes else statement code block.
Syntax:
if (Boolean_condition) //Statement1 else //statement 2
Example: Check the condition for voting
integer age=20;
if(age>=18) //checks the condition
{
System.debug('ELIGIBLE FOR VOTING');
}
else
{
System.debug('NOT ELIGIBLE');
}
Output:
In the above example, the conditional statement returns true because it matches the given condition.
Example:
integer marks=28;
if(marks>=33)
{
System.debug('PASS');
}
else
{
System.debug('FAIL');
}
Output:
In the above example, the conditional statement returns false because it doesn`t match the given condition.
Example: Comparing two different ages
integer age1=22; //my age
integer age2=20; //my brother`s age
if(age1>age2)
{
System.debug('I am elder');
}
else
{
System.debug('My brother is elder');
}
Output:
If else if Statement
Syntax:
if (expression1)
{
//statement
else if(expression2)
{
//statement
}
else if(expression3)
{
//statement
}

else
{
//statement
}
Example: Positive Number
integer num=10;
if(num>0)
{
System.debug('Number is positive');
}
else if(num<0)
{
System.debug('Number is negative');
}
else
{
System.debug('Number is Zero');
}
Output:
Example: Negative Number
integer num = (-50);
if(num>0)
{
System.debug('Number is positive');
}
else if(num<0)
{
System.debug('Number is negative');
}
else
{
System.debug('Number is Zero');
}
Output:
Example: Zero
integer num=(0);
if(num>0)
{
System.debug('Number is positive');
}
else if(num<0)
{
System.debug('Number is negative');
}
else
{
System.debug('Number is Zero');
}
Output:
Example:
integer place=1;
String medal_color;
if(place ==1)
{
medal_color='gold';
}
else if (place==2)
{
medal_color='silver';
}
else if(place==3)
{
medal_color='bronze';
}
else
{
medal_color='null';
}
System.debug('You have scored '+medal_color + 'Medal. Congratulations');
Output:
Example:
integer top_score=99,second_score=80,your_score=85;
if(your_score>top_score)
{
System.debug('You have scored the highest marks');
}
else if((your_score<top_score)&& (your_score>second_score))
{
System.debug('You have scored greater than the second score');
}
else if((your_score<top_score)&&(your_score<second_score)&&(your_score>65))
{
System.debug('You can do better');
}
else
{
System.debug('Work hard');
}
Output:
In the above example, we have created three integer variable top_score, second_score, your_score, and initialized them with 99, 80, 85 values.
In first if block, we are checking if your_score is greater than top_score i.e., 85>99, so the first if block will not get executed because the condition is false.
In the next else block, if your_score is less than top_score i.e., 99<85 (this condition is true) and the second condition is your_score is greater than second_score i.e., 85>80 (this condition is true).
There is a && operator. In the && operator, both the condition needs to be true. So, this block will get executed because both these conditions are true.
Once any of the blocks gets executed, the rest of the conditions will be skipped.
Example:
integer salary=250000;
Decimal bonus,salary_after_bonus;
if(salary>=200000)
{
bonus=15;
}
else if(salary>=150000)
{
bonus=12;
}
else if(salary>=10000)
{
bonus=10;
}
else
{
bonus=5;
}
salary_after_bonus=salary+(salary*(bonus/100));
System.debug('Salary '+salary);
System.debug('Bonus '+bonus+ '%');
System.debug('Salary after bonus'+ salary_after_bonus);
Output:
