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);

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.
