Find Differences between two files/folders and change or merge content

Hi all,

When I was working with 2 similar kind of files. Both files will have the same content except some few changes in words or lines. I was experimenting on one file and i finalized the file. I don't want to repeat the same steps in 2nd file, as what I have done for the 1st file.

I remembered one command in UNIX called diff, which will get the differences from 2 files. So, I have searched for similar command in Windows and I got DiffMerge GUI tool.

DiffMerge is an application, which shows the differences between 2 files visually to the user. It got one more weapon called merging the content.
Once we found the differences between 2 files, we can change or merge the content in the file. It is just a click away.

I personally felt that, this will be very useful for the developers, who are developing similar kind of programs for two or more different clients.

Java/Android Currency (Money) Field Validation

Hi everyone,

Today, I have come across one situation where money(currency) field has to be validated. According to Indian currency, we will consider 2 digits after period(.)

When I want to validate the particular field, I have tried with substring() and indexOf() methods. But I am not getting the expected result. I want to have the output ending with .##, So, I have come to know about NumberFormat class from java.text package.

Here goes sample code with output:
Input: 234 / 234.232 / 234.3
Output: 234.0 / 234.23 / 234.3

NumberFormat nf = new DecimalFormat(".##");
System.out.println("Input: "+234+"Output: "+nf.format(234));
