Java linklist Code
1) read from output file
eg: 1222222 + 2333333
3444444 - 9999999
6666555 * 7
2) For addition and sutraction, Number1 and Number2 should be large integers and must be stored in a link list.
eg.output = 1222222 + 2333333 =
3) For multiplication, Number1 should be stored in a link list and the small integer in a variable.
output = 66666555 * 7 =
4) Write to output file
When I try to read from the output file, this error is generated
!!Error :Variable last might not have been initialize
Help me to clarify the issue becuase i don't think I have to initialize "last" as it has already been declared as a node type.
