Reports if statements that can be replaced with switch statements.

The replacement result is usually shorter and clearer.

Example:

After the quick-fix is applied:

This inspection only reports if the language level of the project or module is 7 or higher.

Use the Minimum number of 'if' condition branches field to specify the minimum number of if condition branches for an if statement to have to be reported. Note that the terminal else branch (without if) is not counted.

Use the Suggest switch on numbers option to enable the suggestion of switch statements on primitive and boxed numbers and characters.

Use the Suggest switch on enums option to enable the suggestion of switch statements on enum constants.

Use the Only suggest on null-safe expressions option to suggest switch statements that can't introduce a NullPointerException only.
