Please help me to creating dynamic VARIABLE in java, with predefined name.

You can't without substantial byte code fiddling. Better use a Map<String, Object>
in which you store the associations between names and values.

kind regards,

HOW TO DO THIS ?


//Variable Declaration
String col_width_1 = "100px";
String col_width_2 = "150px";
//etc String col_width_N = "XXXpx";

//loop
for (int h = 0; h < hrecset.getRowC ount(); h++)
{
//some code
//create the variable name with a concat with the loop counter variable name to get the value of the concatened variable
out.println("<t d style=\"width: "+col_width_+h+ " \">")//Do you understand what i mean?
//some code
}

Use an array or read my first reply; btw, don't hijack threads; it is considered rude. Start your own thread instead.

Don't use this .. because every time the system executes hrecset.getRowC ount().
Instead use,

int rowCount = hrecset.getRowCount();
for (int h = 0; h < hrecset.getRowCount(); h++)
{
 //some code
}

Possibly a typo on your part but you posted the same code that he used.
