    Conditional Statements To make a branch or decision in your program  use the following syntax: if (somethingIsTrue()) { doSomethingCool(99); } If you have an alternative choice, add this: else { doSomethingLame(0); } The syntax is NOT: (for all you BASIC lovers)   if () then

    Conditional Statements You only get one ‘else’ per ‘if’, so this doesn’t  work (or even make sense) if (something()) { shoutHoorah(); } else { doSomethingCool(99); } else { doSomethingLame(0); }

    Nested Conditionals If you need to make a decision that’s based on a  previous decision, you can nest… them… if (itsADog(dog)) { if (iLikeDogs(me)) me.shoutHoorah(); else me.shoutBoo(); } else { if (itsACat(cat)) me.shoutBoo(); if (itsACow(cow)) me.runAway(fast); } these are all nested inside the first selection

    Nesting When you’re nesting any code, make sure  you indent properly. Proper indentation is good for debugging  and also for the sake of anyone else who  has to look at your code.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
