doing it by using if-else is better. idea of putting code in separate function is awesome. thanks to all for showing interest.

Re: Swaping objects

ok i got it.
thanks once again.

Re: Swaping objects

Its perfectly working.
but what you did here is the same i did in my code the only difference is that i did it in separate class.
in your 1st post you said

In your sw method just you are swapping the reference. Not the original values.

i just want to know that whats the difference what you did in last post and in my first post.
according to your logic it should also be by reference

Re: if-statements in java

if two compared string are initialized at the time of declaration and than compared it will work finely

String a="xyz";
String b="xyz";
if(a==b)
{
//executed
}

in this case String b will not take separate memory instead it will refer to same memory location referring by String a. if you will initialize any one of them at run time than it will never effect other one instead it will take separate space.

Re: Swaping objects

thank you sir i got your point.
one more question
is there any way to swap value of two objects without referring to their instance fields by using only objects. is there any more method to do this??

aman rathi 3 Junior Poster in Training

Re: if-statements in java

if (name1 == "good")

replace by this

if(name1.equals("good"))
{
}

likewise all if conditions.

System.out.println(i+"\n"+j);
}

static void sw(emp a, emp b)
{
emp temp;
temp=a;
a=b;
b=temp;
}
}



class swap{
public static void main(String arg[])
{
emp e1=new emp(10,10);
emp e2=new emp(20,20);

Re: loops

i am using turbo c++ and i wrote another program where i define an integer
int size=5,arr;
but my compiler shows an error: on arr (constant value required).
now talking about your above program as far as my concern your logic seems correct

b[i]=b[i-1]+b[i-2];

but i think there is error in syntax.
if you want i can re write your program by changing little syntax.
can you tell is this program compiled successfully on your compiler.

By using this code you can find biggest and smallest number also you can sort a whole list of numbers in ascending order. Here in this program i used selection sort method you read more methods of sorting in your book good luck.

Re: what does it mean??

This [] type of symbol is used in arrays and using it twice ([][]) called two dimensional arrays and using thrice ([][][]) called three dimensional array.
by using arrays one can save his unnecessary efforts by declaring extra variables.....
for eg: you can add 10 numbers by declaring 10 different variables
(just an eg: for a very beginner)
(int v1,v2,v3.....,v9,v10) but it will takes your lots of time and extra effort you can also do it by using a simple and reliable declaration int v[10]. This declaration means now you can store 10 integers in memory. you can use loops for easy initialization for eg:

for(i=0;i<=9;i++)
scanf("%d",&v[i]);

now again look up at your problem....

char a[10][10]= {....}

this means you declare a two dimensional array having 10 columns and 10 rows which will be assign at run time (may possible at compile time)

= {....}

you can initialize any array at compile time as well as run time depends on your program.
i hope you understand this topic little bit by reading this......
for more details you must go though deep study of books and spend time on your system.
