How this Keyword Work in this program and problem in returning object?

Consider the fallowing example.

public class TestingThis {

int a=0;
TestingThis(int b){
public TestingThis myPrint(){
System.out.println("Your value is : " + this);
return this;
public String toString(){
return a +"";
public static void main(String args[]){
TestingThis ba=new TestingThis(10);
TestingThis ba1=new TestingThis(11);

1) In above program how this keyword in return  statement returns and in print statement calls the toString method, How this work internally in java compiler?

2) In last line of the program ba1.myPrint() statement i didn't assign return value to any object,When compile this program didn't get any error and when run this program it work's fine.My question is,Where the return object is stored? How java compiler work for this?

Give me the solution for this Hard-disk Problem.

I am using Windows Xp service Pack 2.Due to some problem I have tried to Format the System. When I tried to Format my system using Xp service Pack 2 , I got Partition  window and I Formatted my C drive and then continue my process, After that selection for OS I got an error Something like “Hard Disk May crash or Check out Power Cable”. I check out my power cable, it’s well. Then restart the machine same problem continues. So that gets into an idea of Backtrack Linux. I have made it live and Boot via USB. Work’s Fine. In terminal window I am trying Hard Disk via fdisk command and disktype command it shows error something like “disktype: data read failed at position 0”,” unable to read /dev/sda”.

Is it any chance to make it work via Backtrack or some other way ? 

If possible post you command here or mail (svelmuruganrvs@gmail.com) me the procedure document.

Why Eclipse show this error?

Program :-

class A
int a;
float b;
double c;
String s;
StringBuilder s1;
StringBuffer s2;
public A(int a,float b,double c,String s,StringBuilder s1, StringBuffer s2)
b=(float) 9.0;
public String toString(){
return a + " : " + b + " : " + c + ": " + s + ":" + s1+":"+s2;
public class ClassTestCopy {
public static void main(String[] args) {
A a=new A(1, 2, 3,null, new StringBuilder("Null"),new  StringBuffer("hello"));
A b=a;

Error in Eclipse:-
Exception in thread "main" java.lang.NoSuchMethodError: A.<init>(IFDLjava/lang/String;Ljava/lang/StringBuilder;Ljava/lang/StringBuffer;)V
at ClassTestCopy.main(ClassTestCopy.java:25)

Javac Ouput :-
1 : 9.0 : 3.0: null:Null:hello
1 : 9.0 : 3.0: null:Null:hello

But when compiled by myself using javac and when run using java compiler it working fine. Then what is the problem in Eclipse?

How this problem occur in Java?

Example Program :

public class TestME {
public static void main(String args[]) {
StringBuilder s=new StringBuilder("Hello");
StringBuffer s2=new StringBuffer("Hello");
String s1="Hello";
new StringTest(s);
new StringTest(s1);
new StringTest(s2);
System.out.println("String Builder :" + s);
System.out.println("String :" + s1);
System.out.println("String Buffer :" + s2);

Integer i=0;
IntegerTest t=new IntegerTest(i);

class StringTest{
StringTest(String s){
StringTest(StringBuilder s) {
s=new StringBuilder("Welcome");
StringTest(StringBuffer s) {
s=new StringBuffer("Welcome");
class IntegerTest{
IntegerTest(Integer s){

Integer and String are Reference type. Then When we pass an argument it will pass as Reference .Once we change the argument value then it will also affect in argument original value.In this program it will not change the original value.How this stuff work's? and also what is the Difference between StringBuilder and StringBuffer ?

Post your command in command box and also mention if anything went wrong in this post.

Program Output :-

String Builder :Hello
String :Hello
String Buffer :Hello

Excepted :-

String Builder :Welcome
String :Welcome
String Buffer :Welcome
