Fall 2012 .S Pes) what the output o, .he bew coda men. , [5 pts) what is the output of tho below code? string hane Mack int valname JengthO ystem.out printinival) 7. [15 pts) See coding instructions lower on the page implement a class Cube. A cube has side length (a double) Provide a constructor with one argument public Cube (double sideLength) and methods public double getsideLength) public double get Vo lume / //volumes Ls calculated a side side side publie double growcube (double growength) increases the Supply a CubeTester class that tests all methods. You may lose points if you don't pay special attention to the following in your program: . Your code should be properly indented . Use appropriate data types, e.g, use integer data types where there will be no need to store floating point numbers. . Avoid magic numbers, i.e., use named constants instead of numeric/string literals and wri a short comment that explains its purpose. E.g., final double Pl = 3.14; //value of pi area Pl radius radius; instead of area 3.14 radius radius Mid Exam Page 3 of 4Explanation / Answer
1) valid/Invalid
3_stooges --> Invalid suffix "_stooges" on integer constant
stooges#3 --> Invalid stray #
threeStooges --> Valid variable name
3stooges --> Invalid suffix on integer constant
2) code segment is
int mystery = 0; // Initial value of mystery is "0"
mystery = val + 10; // now, mystery stores the value 10. i.e, mystery = 0+10 = 10.
3) Program
public class Test // Test is class name
{
public static void main(String[] args)
{
System.out.println("45 + 6"); // It displays 45+6 as output.
System.out.println(45 + 6); // It displays 51 as output.
}
}
Output
45 + 6
51
4) Given sequence
int mystery = 5; // Initial value of mystery is "5"
mystery = 2 * mystery + 1; // now, mystery stores the value 11. i.e, mystery = 2*5+1 = 11.
mystery = mystery - 1; // mystery = 11-1 = 10.value 10 is stored in mystery variable.
5) code fragment
String river = "Thames"; // String variable river stores "Thames"
river = river.replace("hame","am"); // It replaces the string "Thames" as "am" insteed of "hame".
System.out.println(river); // It displays output as --> Tams.
Output
Tams
6) code
String name = "Mark"; // String variable name stores "Mark"
int val = name.length(); // length of string that stored in name variable is taken and stores the length in val variable.i.e, Mark has 4 letters.
System.out.println(val); // It displays output as --> 4 .
Output
4
