So if that line is a method, we'll execute that entire method in one fell swoop. When our code hits a breakpoint during debugging, we can step over the current line with Run – Debugging Actions – Step Over ( F8).

We can toggle a breakpoint at the current line with Run – Toggle Breakpoint – Line Breakpoint ( Ctrl + F8 / Cmd + F8). We view the current breakpoints with Run – View Breakpoints ( Ctrl + Shift + F8 / Shift + Cmd + F8). We can still save all files manually with File – Save all ( Ctrl + S / Cmd + S). IntelliJ IDEA automatically saves our code, for instance, before running it.

That is Ctrl + Shift + / in Windows and Alt + Cmd + / in macOS. We can even comment out a whole block of code with Code – Comment with Block Comment. We can use Code – Surround with ( Ctrl + Alt + T / Alt + Cmd +T) to put control structures around our code, such as an if statement. And with Code – Generate ( Alt + Insert / Cmd + N), we can create common methods like getters, setters, or toString().

Code – Code Completion – Complete Current Statement ( Ctrl + Shift + Enter / Shift + Cmd + Enter) finishes our current line.Ĭode – Override Methods ( Ctrl + O) lets us pick inherited methods to overwrite.

We may need to type a closing parenthesis and have to put a semicolon at the end. This function also automatically launches after a brief delay in the default IntelliJ IDEA configuration. When we start to type the name of variables, methods, or types, IntelliJ IDEA helps us finish those names with Code – Code Completion – Basic ( Ctrl + Space). Once we arrive at the right file and the right place, we can start editing our code.
