Hi,

I want to use Type 4 Oracle Driver in servlet.(oracle.jdbc.driver.OracleDriver).

Where I can place classess111.jar file in weblogic server?

FileInputStream fin=new FileInputStream("tata.doc");
int i;
while((i=fin.read())!=-1)
{
System.out.print((char)i);
}

If I run above code for abc.java instead of tata.doc -> then its working fine. Its printing containts of abc.java on the console.
But If I run for tata.doc -> then its printing something different on the console.
Why this happen?

what is difference between windowClosing() & windowClosed() methods from WindowListener?

I want to print Hello with underline on the frame. How its possible?

Q1>How to use
protected String paramString() method of Button class?

Q2> How to use
public void addNotify() method of Button class?

If any one having examples for above methods Pl.help me.

1> class Demo1{
static int i=10;// initialize variable i
--------
-------

}
............................................................

2>class Demo2{
static int i;
static {i=10;}// initialize variable i in static initializer block


}

Q. is there any difference between class Demo1 & class Demo2?

In actual project where we can use static block?

But as per previous reply .....
class Demo
{
public static void main(String[] args)
{
float f1=11.2f;
float f2=11.2f;


if(f1==f2)
{
System.out.println("equal");
}
else
System.out.println("Not equal");

}
}


Above code gives me o/p- > equal?

But why you cant use float in switch case?

Can any one tell me,
Why float is not usefull in switch case?
