The Extract Variable refactoring helps you simplify complicated statements in your code. For example, in the code fragment below, you can select an expression in the code:

提取变量重构代码可以帮助您简化复杂的语句。例如,在下面的代码片段中,您可以选择一个表达式的代码:

BufferedInputStream bis=new BufferedInputStream(new FileInputStream(filePath));

and press Ctrl+Alt+V (Refactor | Extract | Variable...). This will result in the following:The Extract Variable refactoring helps you simplify complicated statements in your code. For example, in the code fragment below, you can select an expression in the code:

2 注释

 You can comment or uncomment lines and blocks of code using Ctrl+斜杠 and Ctrl+Shift+斜杠.

Ctrl+斜杠 comments or uncomments the current line or selected block with single line comments (//...).

Ctrl+Shift+斜杠 encloses the selected block in a block comment (/*...*/).

To uncomment a commented block press Ctrl+Shift+斜杠 anywhere inside it.
