Exam 1z0-808 topic 1 question 117 discussion

Answer is C

Correct Answer is D float var1 = (12_345.01 <= 123_45.00) ? 12_456 : 124_56.02f; // 124_56.02f value assigned to var1 float var2 = var1 + 1024; // 124_56.02f +1024 System.out.println(var2); // 13480.02

Indeed, the key aspect here is the return type of the ternary expression, which is determined by the possible types of the operands. In this case, even though the boolean expression involves doubles, the ternary operator considers the common type compatible with both branches, which is float because float can accommodate both 12_456 and 12456.02f. This is why the result is float and not double.

Answer is D. is tested

Answer is D. To test: public static void main(String[] args) { float var1 = (12_345.01 <= 123_45.00) ? 12_456 : 124_56.02f; float var2 = var1 + 1024; System.out.println(var2); }

Answer is D. float var1 = (12_345.01 <= 123_45.00) ? 12_456 : 124_56.02f; float var2 = var1 + 1024; System.out.println(var2); // 13480.02

The answer is the letter D, analyzing the expression, it returns a false, so it returns 124_56.02f (remembering that the _ does not separate the decimal place, it only separates the number, it only serves to help reading) so when adding 12456.02 + 1024 = 13480.02

B, if returns true so double comes. Then it couldn’t be assigned float

Correct answer C

The correct answer C, Tested 13480.0

float var1 = (12_345.01 >= 123_45.00) ? 12_456 : 124_56.02f; float var2 = var1 + 1024; System.out.println(var2);

Correct answer : C - 13480.0 float var1; if(12_345.01 >= 123_45.00){ var1 = 12_456; }else{ var1=124_56.02f } => the condition is true : 12345.01 > 12345.00 => var1 = 12_456 which means 12456 (The underscore is useful just for the readability). Then var 2 = var1 + 1024; => var 2 = 13480 => Output: 13480.0.

tested. correct id D. but still can't say why

this is a tricky question. the boolean statement is double and double doesn't fit inside the float. Looks like false/true return type matters here, not data type inside the boolean expression.
