not all abstract classes have abstract methods.

The strings are not the same objects so the == comparison fails. See note #1 below.
As the value of the strings are the same equals is true. The equals method compares values for
Note: #1 ==
Compares references, not values. The use of == with object references is generally limited to the
Comparing to see if a reference is null.
Comparing two enum values. This works because there is only one object for each enum constant.
You want to know if two references are to the same object.

First line:
System.out.println("Result: " + 2 + 3 + 5);
String concatenation is produced.
Second line:
System.out.println("Result: " + 2 + 3 * 5);
3*5 is calculated to 15 and is appended to string 2. Result 215.
The output is:
Result: 235
Result: 215
Note #1:
To produce an arithmetic result, the following code would have to be used:
System.out.println("Result: " + (2 + 3 + 5));
System.out.println("Result: " + (2 + 1 * 5));
Result: 10
Result: 7
Note #2:
If the code was as follows:
System.out.println("Result: " + 2 + 3 + 5");
System.out.println("Result: " + 2 + 1 * 5");
The compilation would fail. There is an unclosed string literal, 5", on each line.

NO.8 Given:
package p1;
public class Test {
static double dvalue;
static Test ref;
public static void main(String[] args) {
What is the result?
A. p1.Test.class
B. <the summary address refrenced by ref> 0.000000
C. Null
D. Compilation fails
E. A NullPointerException is thrown at runtime
