java - Jshell 如何在行尾没有分号的情况下工作

Question

我是 java 9 的新手，只是在 jshell 上练习一些代码片段

 jshell> System.out.println("hello");
 hello

 jshell> System.out.println("hello")
 hello

在这两种情况下，我都得到 hello 的输出，但 jshell 在行尾没有分号的情况下工作。我知道java需要分号

Answer 1

Jshell 自动添加分号。 Doc-Page-2-1或here

Snippets of Java code are entered into JShell and immediately evaluated. Feedback about the results, actions performed, and any errors that occurred is shown

Note:

Terminating semicolons are automatically added to the end of a complete snippet if not entered.
