Advanced Insert Mode Entry
Task Instructions
Master all the ways to enter insert mode for different situations
Fix the Java class using different insert mode entries. Use 'A' to add semicolons at line ends, 'a' to add braces after methods, 'o' for closing braces on new lines, 'O' for annotations above, and 'i' for inline edits.
Learning objectives
- Master all insert mode entry methods
- Understand when to use each method
- Develop efficient editing patterns
Required keystrokes
Your submission is checked for these keystrokes, not just the final text — so reach for the technique, not a workaround.
- i Use insert mode
- a Use append mode
- A Use append at end of line
Helpful commands
- i
- Insert at cursor
- a
- Append after cursor
- I
- Insert at beginning of line
- A
- Append at end of line
- o
- Open new line below
- O
- Open new line above
Stuck? Peek at a hint 3 hints · try it on your own first
- I = insert at beginning of line, A = append at end of line
- o = new line below, O = new line above
- Choose the right entry point to minimize keystrokes
public class User {
private String name
private int age
public User(String name, int age)
this.name = name
this.age = age
public String getName()
return name
public void setName(String name)
this.name = name
// Add: semicolons at line ends (A)
// Add: opening braces after methods (a)
// Add: closing braces on new lines (o)
// Add: @Override annotation above setName (O)
// Add: 'final' before parameters (i)
