Redundant 'else'
Reports redundant else
keywords in if
—else
statements and statement chains.
The else
keyword is redundant when all previous branches end with a return
, throw
, break
, or continue
statement. In this case, the statements from the else
branch can be placed after the if
statement, and the else
keyword can be removed.
Example:
if (name == null) {
throw new IllegalArgumentException();
} else {
System.out.println(name);
}
After the quick-fix is applied:
if (name == null) {
throw new IllegalArgumentException();
}
System.out.println(name);

Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.
ConfusingElseBranch
Disable the Report when there are no more statements after the 'if' statement option to ignore cases where the if
—else
statement is the last statement in a code block.
Here you can find the description of settings available for the Redundant 'else' inspection, and the reference of their default values.
