Hello Ranchers,

I have Cleared SCJP5.0 with 63%.This is not a good score but iam happy that i have cleared it.

Can anybody tell me what is the process of getting logo of Certified person,and in how many days will i get the certificate from SUN.

it is giving compile time error at line 1,5

class MCZ11 {
public static void main (String[] args) {
char a = '\c'; //line 1
char b = '\r';
char c = '\"';
char d = '\b';
char e = '\p'; //line 5
}}
please explain me why

please give me clear detail about the equals method and the "==" with a program and output explanation

1: if( new Boolean("true") == new Boolean("true"))
2: System.out.println("True");
3: else
4: System.out.println("False");

explain the program and output

explain program in full detail

01: class MyClass {
02: static int maxElements;
03:
04: MyClass(int maxElements) {
05: this.maxElements = maxElements;
06: }
07: }
08:
09: public class Q19 {
10: public static void main(String[] args) {
11: MyClass a = new MyClass(100);
12: MyClass b = new MyClass(100);
13:
14: if (a.equals(b))
15: System.out.println("Objects have the same values");
16: else
17: System.out.println("Objects have different values");
18: }
19: }

i thought the output will be
Prints "Objects have the same values"
but the output is "Objects have different values"

Hello ranchers,

I have one week for the exam,and i am not able to get good score so what should i do.I have read K&b 2 times but iam not able to get the flow of the programs.My percentage of mock exams are around is 50 - 55%.

How program flow is going on please explain in detail

import java.awt.Dimension;
class ReferenceTest1
{
public static void main(String[] args)
{
Dimension d=new Dimension(5,10);
ReferenceTest1 rt=new ReferenceTest1();
System.out.println("Before modify() d.height="+d.height);
rt.modify(d);
System.out.println("After modify() d.height="+d.height);
}
void modify(Dimension dim)
{
dim.height=dim.height+1;
System.out.println("dim="+dim.height);

}
}

How program flow is going can any body explain me in detail .



class ReferenceTest
{
public static void main(String[] args)
{
int a=1;
ReferenceTest rt=new ReferenceTest();
System.out.println("Before modify() a="+a);
rt.modify(a);
System.out.println("After modify() a="+a);
}
void modify(int number)
{
number=number+1;
System.out.println("number="+number);
}}

can anybody explain me the working of this program........?

class Top{
public Top(String s)
{
System.out.print("B");
}
}

public class Bottom2 extends Top
{
public Bottom2(String s)
{
System.out.print("D");
}

public static void main(String[] args)
{
new Bottom2("C");
System.out.println(" ");
}
}


The output is :"compilation fails".
Iam not able to understand how does the above output comes( ).

Thank you for replying , the above two answers are the best answers for me.

Thank you once again

can you explain me the output in detail:

class Red {
public int a;
public static int b;
public static void main (String[] in) {
Red r1 = new Red();
Red r2 = new Red();
r1.a++;
r1.b++;
System.out.print(r1.a+", "+r1.b+", "+r2.a+", "+r2.b);
}
}

output:1,1,0,1

How does this output comes?explain

Hi friends, can you just explain what "equals" and "instanceof" used for.what is the difference between them.

Can their be a static variable in a inner class?

can a inner class have static variable?
can someone explain about"Method local inner class"?
