if / else if / else

Know how to write an if statement that includes else if and else blocks to control program flow.

if (condition){
}
else if (next condition){
}
else{
}

The (condition) in the if statement above must be an expression that can be true or false. This is known as a boolean expression.

Some examples of a boolean expression are:

password.equals("password")
school.equalsIgnoreCase ("The League")

count == 10
count >= 33

Notice that to test if a String variable contains a particular value, you need to use the equals or equalsIgnoreCase method, whereas for an int you can use ==

It is a good idea to always have an else block for an if statement, so you catch any condition you didn’t think of.
