Question

Java中如何将一个较长的字符串分成多行了书写

Answer 1

把大的list分成一个个小的list， 再用map储存

Answer 2

这个还真不好说。。

如果说只是String字符串的话，
String str = "aaaa\nbbbbbb\nccc";
String[] len = str.split("\n");

System.out.println(len.length);
但是你要是从inputStream之类的读取，用BufferedReader之类的吧

Answer 3

You can use auto-formatting (CTRL + ALT + L), after few changes in Code Style settings.

• Press CTRL + ALT + S to open Settings window

• Find Code Style / Java section

• Make sure to uncheck "Line Breaks" option and check "Ensure right margin is not exceeded" option

• Press OK to accept changes you've made

Now when using auto-formatting (CTRL + ALT + L) long strings exceeding line character limit will be automatically cut into multiple lines.
