Question
Analyze the following code: public class Test { public static void main(String[] args) { double[] x = {2.5, 3, 4}; for (double value: x) System.out.print(value + " "); } } Group of answer choicesThe program displays 2.5, 3, 4The program displays 2.5 3 4The program displays 2.5 3.0 4.0The program displays 2.5, 3.0 4.0The program has a syntax error because value is undefined.
Solution 1
The program displays 2.5 3.0 4.0. This is because the code is written in Java, and it creates an array of double values. The for-each loop then iterates over each value in the array, printing each one with a space after it. Since the values are of type double, they are printed with a decimal point and a trailing zero if necessary.
Solution 2
The program displays 2.5 3.0 4.0. This is because the code is written in Java, and it creates an array of double values. The for-each loop then iterates over each element in the array, printing each one with a space (" ") after it. Since the elements are of type double, they are printed with a decimal point and a trailing zero if the number is a whole number.
