Split Parameter value for the excel sheet name in Jasper Report [duplicate]

Question

I am generating an excel file with multiple sheets from Jasper.

I am getting some comma(,) separated values in Jasper's input

for eg:- 000324,000323,000322.

I want to split this value and give them as the sheet names in a single excel file.

As we can see in the above example we are having 3 inputs so 4 excel sheets will be generated first sheet name will be given as info and the remaining should be named 000324,000323 and 000322.

if there are 4 inputs then 5 excel sheets will be generated in a single excel file and apart from the first sheet other sheets will be named from that 4 values which will be taken as comma separated in the input field (eg: 001,002,003,004).

I am new to Jasper Report so can anyone help me to split this input and give the name to the excel sheets.

Thanks in Advance!
