[Java] Memo on how to write the source

I learned a new word today. The word [coding convention]. Of course, I think there are subtle differences depending on the site. There was a beauty rule in the clean sauce ☆

It's hard to get it right away, but ... seniors say "Make a check sheet and check it." I made an Excel sheet separately from this memo.

So, memo memo.

■ {[Space] in front of (wave brackets)

■, [Space] behind (comma)

■ [Space] before and after =, +, <,>,

■ In the if statement, else and else if ... Continue with a space after the closing parenthesis of if}

  if(int i = 0; i < a.length; i++) {
  
  } else {
  
  }

■ Pay attention to the indent (check what the paragraph is like)
