    Hi.
    I would like to ask you guys what is the difference between these sentences (I learned the if stuff but I learned more ways so just wanna know if it's the same or not):
    I hope it correct. I wanna say: If you come, I will laugh.

    もしあなたはくるなら私は笑います。

    あなたは来たら私は笑います。

    あなたはこれば、 私は笑います。

    あなたは来る場合、 私は笑います。

    So are they the same? Or are there more way how to express if statement? And which one is the most common to use?
    どうも ありがとう

    Not a native Japanese speaker, but for me I get the following impressions:
    1) なら adds emphasis to the condition. So if you come, I will laugh.
    2) たら adds emphasis to the result. So if you come, I will laugh.
    3) ば is the most neutral of all. It's like an "if... then..." statement in Maths.
    4) 場合 is like "in the case of" and is sort of formal. It seems to express some situation that will cause an effect.

    お役に立ったかな?

    日本語は母語の方は意見を教えていただけないでしょうか。

    The fourth one is easiest; as jamesh625 said, 'In case of/that~'. In Japanese, this is good when you select one from two or more.
    'In case of using product A, (not B, C..)' 製品Aを使用する場合は・・

    あなたが来るなら、私は笑います。
    あなたが来たら、私は笑います。
    あなたが来れば、私は笑います。

    They are all OK.

    I'll speak roughly..the first and the third ones are more hypothesis, 'a for-example-story'. なら and ば both work especially for hypothesis. You don't know if sb will come and you don't care about the possibility much.
    But the second one is different. This is when sb is more likely to come―becoming a reality more than the two. So this can be 'When you come~', too.

    Don't forget we often mix them breaking the wall of hypothesis vs likelihood. ば is often two-way.
