substrings

Posted: Oct 19, 2003 10:27 PM

I am trying to figure out a way to insert a second string into a first string to make a new string. I'm trying to figure out how to utilize the substrings with a position integer so that my input will apply.

if the length of the String is 20 and if you want to insert after 10th position

You have to take a subsstring from start {0} to the point{10} where you want to insert the new string and store in a variable. The from 11 to 20 subsstring and keep it in another variable and then add the three string together where your string which needs to be inserted is in the middle. Or use StringBuffer to do the concatenation.

String are immutable so you can insert something in the middle of already existing string with out creating a new String.

I might have made a mistake with the indexes please reffer the Java Doc for Strings on substring. I am not sure the indexes are inclusive or exclusive
