Question

What is the output of the program segment below?

final int num1 = 100;
final double num2 = 123.321;
System.out.println(num1 + " " + num2);
(A) 100 123.321
(B) 123.321 100
(C) 100 123
(D) Error message

Answer 1

The program segment in Java prints out the values of an integer and a double-precision floating-point number exactly as they are declared, resulting in '100 123.321'.

Step-by-step explanation:

The output of the provided program segment is not related to the calculation performed by a calculator. Instead, it is determined by the way the Java programming language handles string concatenation and printing values. The program segment declares two final variables, num1 with a value of 100, which is an integer, and num2 with a value of 123.321, which is a double-precision floating-point number.

When the System.out.println statement is executed, it prints the values of num1 and num2 as a string, separated by a space. Therefore, the program will output the integer and the double exactly as they are declared, resulting in 100 123.321.

The correct answer to the question is: (A) 100 123.321
