CTRL+SHIFT+F
It is used to perform a “format”.
CTRL+SHIFT+F “Formats” the selected code or file. This tool automatically formats your code according to project coding norms like indentation, line space, and bracket placement.
Pressing CTRL+SHIFT+F reformats the selected code or the entire file according to project formatting guidelines. This can make your code more readable and consistent with team or organizational conventions.
“Windows” -> “Preferences” -> “Java” -> “Code Style” -> “Formatter” in Eclipse’s main menu allows you to customize formatting rules.
CTRL+SHIFT+F can also “Cleanup” the targeted code or the entire file. This feature automatically fixes unused imports, missing Javadoc comments, and deprecated code.
CTRL+1:

Eclipse analyses the code at the cursor and suggests fixes when you hit CTRL+1. Press Enter to apply a fix after using the up and down arrow keys to navigate the list.
Quick Correct may instantly fix common coding bugs without manual intervention. It saves time and effort, especially for large projects with many files and sophisticated code.
CTRL+1 can also suggest code completion and restructuring, such as renaming variables and methods, adjusting access level, creating getters and setters, etc.
“Windows” -> “Preferences” -> “Java” -> “Editor” -> “Quick Fix” in Eclipse’s main menu allows quick fix configuration.
CTRL+SPACE
CTRL+SPACE activates “Content Assist” (code completion). This functionality autocompletes code sentences, variables, method names, etc.
Eclipse analyses code at the cursor and suggests code completions when you click CTRL+SPACE. Use the up and down arrow keys to browse the list of completions and hit Enter to put it into your code.
By suggesting variable and method names, import statements, and other code constructions, Content Assist speeds up code authoring. It saves time and effort, especially for large projects with many files and sophisticated code.
CTRL+SPACE can also display variables, methods, and other context-specific choices.
“Windows” -> “Preferences” -> “Java” -> “Editor” -> “Content Assist” in Eclipse’s main menu lets you set Content Assist.
CTRL+SHIFT+L
CTRL+SHIFT+L displays the perspective’s keyboard shortcuts. This tool helps you master Eclipse’s keyboard shortcuts rapidly.
CTRL+SHIFT+L opens a dialogue box with all keyboard shortcuts arranged by category. The scroll bar or search function might help you find a keyboard shortcut.
