Java Remove duplicate lines from first file comparing second file

Hi,
I have two files with below data::
file1:-
Code:
123|aaa|ppp
445|fff|yyy
999|ttt|jjj
555|hhh|hhh

file2:-
Code:
445|fff|yyy
555|hhh|hhh

The records present in file1, not present in file 2 should be writtent to the out put file.
output:-
Code:
123|aaa|ppp
999|ttt|jjj

Is there any one line command for this? please share with me.

Thanks in advance.

Thanks all...
The command is working fine.

Can we put the output file as file1?? (the original file should be my output file).
