I am working on something where i need to search and replace many variable names of a program.
I have a class Hello and its public variable is world, but the variable world has been changed to earth so now in the program i need to go and replace the world variable with earth. this is just one example but there are many different
variables to be replaced. code ..... [B]Hello.world[/B] replace by [B]Hello.earth[/B] code ....
so far i have a 2D array with old variable name and new variable name
but i am not able to find the strings such as world since it is in a single word Hellol.world
Please help on how to look for world in AnyClassName.old_VariableName and replace it by AnyClassName.new_VariableName
