java - 如何在 Java 中打断长行

Question

在official document of Oracle about coding conventions他们写道:

"Following are two examples of breaking an arithmetic expression. The first is preferred, since the break occurs outside the parenthesized expression, which is at a higher level."

longName1 = longName2 * (longName3 + longName4 - longName5)
 + 4 * longname6; // PREFER

longName1 = longName2 * (longName3 + longName4
 - longName5) + 4 * longname6; // AVOID

“更高级别”是什么意思？与表达式中的求值顺序有关吗？

Answer 1

来自官方文档的先前声明:

"Prefer higher-level breaks to lower-level breaks"

换句话说，避免因可读性而破坏嵌套表达式。

表达式嵌套在括号中的次数越多，级别越低。
