我有一长行代码,我想在多行中分解。我用什么,语法是什么?
例如,添加一堆字符串:
val text = "This " + "is " + "a " + "long " + "long " + "line"

Kotlin 中没有续行符号。由于它的语法允许几乎所有符号之间有空格,因此您可以中断语句:
val text = "This " + "is " + "a " +
"long " + "long " + "line"
但是,如果语句的第一行是有效语句,它将不起作用:
val text = "This " + "is " + "a "
+ "long " + "long " + "line" // syntax error
为了避免在跨多行中断长语句时出现此类问题,您可以使用括号:
val text = ("This " + "is " + "a "
+ "long " + "long " + "line") // no syntax error
