Java Experts...Help needed to correct code' Aug 30th 2012, 07:07
I need a java program for my project that reads the contents from one file, replace them and store in new text file...' ' I have text file "filenumber.txt" containing numbers...' The numbers should be replaced with specified character and stored to a new file "filealpha.txt" When I run my code, only string "1" is replaced with character specified...' Rest all remain same...:s' ' I tried a lot but could not succeed...:(whew):' ' Could any1 help me to correct the following java code...:(mm):' (You can also download source code from attachment "Problem_code.rar")' ' '
Code:
/* * Problem: Replace "1" string only instead of all */ import java.io.*; public class Replace { public static void main(String args[]) throws Exception { String str1; String n1 = "1"; String a1 = "A";
