Chains of Conditional Statements

if-else statements can be chained in following form:
if ( Expression₁ ) {
    Statement_1a
    Statement_1b
    ...
} else if ( Expression₂ ) {
    Statement_2a
    Statement_2b
    ...
} else if ( Expression₃ ) {
    Statement_3a
    Statement_3b
    ...
} else {
    Statement_4a
    Statement_4b
    ...
}

The execution evaluates all conditional expressions beginning from Expression₁ until the first expression is found that evaluates to true. Then the corresponding statement sequence is executed, or, if none of the expressions evaluated to true, the statement sequence of the final else part.
