Slot Machine Code Problem

I've got everything finished for the program, but it's telling me that the "else if" won't work because I don't have an "if" but I have the "if" right above it. I tried making them all "if" to see if it worked but then it just makes the player win everytime without being able to exit. I don't know what I'm doing wrong. I appreciate any help. Thank you.

        int Coins = 1000;
        int Wager;




        System.out.println("Slot Machine");
        System.out.println("You have " + Coins + " coins.");
        System.out.println("Press 0 to exit, any other number to play that many coins per spin.");

You are missing the braces! use:

if( boolean equation ) {
    many_statements;
    many_statements;
    many_statements;
}

OR

if( boolean equation ) 
    on_single_statement;

you must put curly braces in every if conditions. not because it's only 1 line of statement you didn't have to use curly braces. Curly braces is essential you must put it.
