IntelliJ IDEA快捷鍵：Ctrl+Shift+空格

The smart type code completion may be used after the new keyword,to instantiate an object of the expected type.For example,type StringBuffer buffer = new and press Ctrl+Shift+空格:StringBuffer buffer = new StringBuffer();

能夠在new關鍵字以後使用智能類型代碼完成來實例化指望類型的對象。例如，鍵入StringBuffer buffer = new並按Ctrl + Shift +空格：StringBuffer buffer = new StringBuffer();
