When invoked for the third time, basic code completion expands the suggestion list to all classes throughout the project, regardless of the dependencies.Ĭompletion in the Stream API chains is aware of type casts, so the list will not only contain items based on the existing call filter(String.class::isInstance), but also automatically typecasted suggestions. This shows inaccessible classes and members as well as static fields and methods. If necessary, press Ctrl+Space for the second time (or press Ctrl+Alt+Space). If automatic completion is disabled, press Ctrl+Space or choose Code | Code Completion | Basic from the main menu. By default, IntelliJ IDEA displays the code completion popup automatically as you type. If the necessary class is not yet imported, it will be imported automatically. When invoked for the third time in a row, IntelliJ IDEA will look for suggestions for classes and interface names in the entire project, regardless of dependencies. Invoking basic code completion for the second time shows inaccessible classes and members (these can be made public by applying an intention action). If basic code completion is applied to a part of a field, parameter, or variable declaration, IntelliJ IDEA suggests a list of possible names depending on the item type. However, IntelliJ IDEA does not recognize the structure of such files, and suggests options regardless of whether they are appropriate in the current context.īasic completion is also available for a non-English keyboard layout. When you invoke code completion, IntelliJ IDEA analyses the context and suggests the choices that are reachable from the current caret position (suggestions also include Live templates).Ĭode completion is available for custom file types.
Basic completionīasic code completion helps you complete the names of classes, methods, fields, and keywords within the visibility scope. This section covers various techniques of context-aware code completion that allow you to speed up your coding process.
