convert characters while writing into outputfile

Gayathri Venugopal

Hello, I have an input_filename which says hello world. In the output file named output_filename, I have to read the input_filename and convert those exact words as upper case.eg: output file name contains HELLO WORLD. Please tell me how do I do that. PS : my code logic is different ,I am just asking this as an example to know, how do I read from a file and convert characters and then write it to output_filename.

Read the Javadoc in the String class and the Files class.  They have the methods you require.
