Is there a hot key or easy way to replace an if-else if statement with a switch in IntelliJ? I would prefer not to manually convert the if-else if statement to a switch. I am looking to be able to highlight the if-else if statement and press a combination of keys or use a menu button.

You can always convert an if statement to a switch statement. The break keyword must be used in a switch statement; otherwise, a syntax error occurs. The default case must be specified in a switch statement.
The if-else statement is used to choose between two options, but the switch case statement is used to choose between numerous options. If the condition inside the if block is false, the statement inside the else block is executed. If the condition inside the switch statement is false, the default statements are run.
A switch statement can replace multiple if checks. It gives a more descriptive way to compare a value with multiple variants.
Update: as @christopheml pointed out in comments on another answer, "Replace If with Switch" seems to have disappeared in IntelliJ 2018.1. A bug has been filed here.
There are IntelliJ intentions named "Replace If with Switch" and "Replace Switch with If". Check your preferences to see if those options are enabled. If so, I would expect that you would see a quickfix option (Option+Enter on Mac, Alt+Enter on Windows) whenever IntelliJ can automatically handle the conversion from one to the other.

I just found out that you have to click on the first if, wait for the light bulb icon to appear and then choose Replace if with Switch.

Android studio (intelliJ idea):
Put your cursor on the switch/if statement and:
mac: option + return
win: alt + enter

If it doesn't offer the replacement anymore, its probably because disabled feature on "Intentions". (Android studio (IntelliJ))
Solution is simple:
