IntelliJ show JavaDocs tooltip on mouse over
问题 In Eclipse, when hovering over a method, variable, etc. a tooltip is displayed with the corresponding JavaDocs. Is there such a feature in IntelliJ? 回答1: For IntelliJ 13 , there is a checkbox in Editor's page in IDE Settings EDIT: For IntelliJ 14 , the option has been moved to Editor > General page. It's the last option in the "Other" group. (For Mac the option is under the menu "IntelliJ Idea" > "Preferences"). EDIT: For IntelliJ 16 , it's the second-to-last option in Editor > General >
