Then can i say all wrapper classes are immutable??

Thaks for your reply!!

But can you please tell me why it happens to integers??

hi

How strings are immutable when compared with integers?

But we are changing the string values like
String s = "abc"

s= s.concat("de");

Hi ranchers!!

I am preparing for SCJP and planing to take soon.One thing i came across from this forum some people are getting 210 minutes who took the exam recently.But in the website it's showing 175.SO please let me know what exactly the time occording to that i will prepare my self for the exam.

Thanks in advance

Thnaks all

1. class Example {
2. public static void main(String[] args) {
3. Short s = 15;
4. Boolean b;
5. // insert code here
6. }
7. }
Which, inserted independently at line 5, will compile? (Choose all that apply.)
A. b = (Number instanceof s);
B. b = (s instanceof Short);
C. b = s.instanceof(Short);
D. b = (s instanceof Number);
E. b = s.instanceof(Object);
F. b = (s instanceof String);

how the answer is D (b aslo)
But expalin how d is also correct??

HI

Please tell me why i1 and i2 are different and i3 and i4 are same

Integer i1 = 1000;
Integer i2 = 1000;
if(i1 != i2) System.out.println("different objects");
if(i1.equals(i2)) System.out.println("meaningfully equal");
Produces the output:
different objects
meaningfully equal

Integer i3 = 10;
Integer i4 = 10;
if(i3 == i4) System.out.println("same object");
if(i3.equals(i4)) System.out.println("meaningfully equal");
This example produces the output:
same object
meaningfully equal

Thanks in advance
