该条件（常规脚本）的返回值是多少？

Question

What will be the return value of this if/else statement?

if (salary <= 3000) {
  return discount < 0.40
}
else {
  return discount < 0.60
}

I'm not sure if the return value of each if and else will be a boolean or 0.40 and 0.60 ?

Answer 1

It is a boolean. The < , > , != , >= , == , <= expressions will evaluate to a boolean value:

def mustDiscount(salary, discount = 0.5) {
    if (salary <= 3000) {
      return discount < 0.40
    }
    else {
      return discount < 0.60
    }
}

mustDiscount(2000).with {
    assert it in Boolean
    assert !it
}


mustDiscount(4000).with {
    assert it in Boolean
    assert it
}

Answer 2

The return type for that would be a boolean (true or false), both in the if block and else block.

Also return discount == 0.50 would return a boolean.
