I am new very new to Java. I am trying to get the data from form and to email.

I am getting 3 fields of form two of them are String and one is array and want to store in one variable as to mail or print.

msg1 is String
msg2 is Array
msg3 is String

Now am trying to store like:

mailmsg=msg1+msg2+msg3;

System.out.println(mailmsg) this gt me the output msg1,last index of msg2 and msg3. I have problem with msg2 as this is array. How can I merge with
mailmsg=msg1+msg2+msg3;

Its Ok when there is a string but when array cames it became very difficuit for me to merge with string and mail it. Please check my following code

Thanks & best regards

String phone=req.getParameter("phone2");
String country=req.getParameter("country");
String[] btype=req.getParameterValues("btype");
 
msg1="<table border=0 cellpadding=4 align=center cellspacing=5 width=500>"+
     "<tr><td class=khan><font color=red>Country</font></td><td class=khan>"+country+"</td></tr>"+
     "<tr bgcolor=#EEEEEE><td class=khan><font color=red>Phone</font></td><td class=khan>"+phone+"</td></tr>";
 
	msg2="<tr><td class=khan><font color=red>Business Type</font></td><td class=khan>";
 
		for(i=0;i<btype.length;i++){
			if(!btype[i].e[]quals("")){
			btype[i]
			}
		}
 
	msg3="</td></tr>";
 
mailmsg=msg1+msg2+msg3;
System.out.println(mailmsg);

if msg2 is an array then you should store and retreive data on/from a particular index. you can do it like msg2[0] = "whatever written stores at index 0"; and so on.

If you are using Java 1.5 or later, there is a convenient toString(Object[] a) method on java.util.Arrays.

So you could write it like this:

mailmsg=msg1+Arrays.toString(msg2)+msg3;

Otherwise, you'll just have to iterate:

mailmsg = msg1;
for(int i = 0; i < msg2.length; ++i) {
    mailmsg += msg2[i];
}
mailmsg += msg3;

If you're going to be doing this a lot and msg2 is going to be a large array, you'll want to build up the string in a StringBuffer (StringBuilder in Java 1.5 or later):

StringBuffer buf = new StringBuffer(msg1);
for(int i = 0; i < msg2.length; ++i) {
    buf.append(msg2[i]);
}
buf.append(msg3);
mailmsg = buf.toString();

Have fun!
