this is java code
-------------------------
Consider the following code:
int [ ] a = [1, 2, 3];
Object o ="123";
String t = "12";
String w = t + "3";
Boolean b = o.equals (a);
Boolean b2 = o.equals (t);
Boolean b3 = o.equals (w);
Boolean b4 = (o == w);
Show the effect of executing this code by means of a diagram similar to that in Figure 2.2. Also explain how the code arrived at the results in b, bl, b2, and b3.

Hi Friend,
Your code:
class Check
{
public static void main(String[] args)
{
int [ ] a = {1, 2, 3};
Object o ="123";
String t = "12";
String w = t + "3";
Boolean b = o.equals(a);
Boolean b2 = o.equals(t);
Boolean b3 = o.equals(w);
Boolean b4 = (o == w);
System.out.println(b);
System.out.println(b2);
System.out.println(b3);
System.out.println(b4);
}
}
returns following output:
false
false
true
false
Thanks
