How to achieve padding( with zero) on textfield.

[manit.deepak]

Our Requirement is to achieve padding with '0' for Number field and '#' to Varchar field:

We have a TextField of width=100. 

When the report is generated, dynamically data is populated into that field.

Let the data populated length be 20. We have right aligned the textfield.

Now the problem is we want to prepend 100-20= 80 Zeros' to the data. How we can achieve the same using Jasper or Java programming?

Thanks

Make use of String.format() function.

String: String.format("%10s", field) will pad spaces at the left of the string. To pad them to the right use String.format("%-10s", field). The amount of spaces to be added will be {10 - field length}

Integer: String.format("%06d", field) will pad {6 - field length} zeros to the left, in this case. It is important to note that the field HAS to be an Integer of any type. Without the zero, the output will be with padded spaces
