Selenium Java Code需要在对代码进行更改时从头开始

I am Using Eclipse, Selenium Web Driver and Java to automate our Web Application. As part of execution in debug mode, i have made a change in the code and saved. But the code changes are not reflecting in the current execution, need to restart the execution from the begin. Please suggest, do we have any solution to continue the execution with the changes made.I am Using Eclipse, Selenium Web Driver and Jav
