Basically I am doing project on Ewon Flexy hardware, Ewon hardware only supports jre javaetk, which is quite old. Now I have to use the concepts of HashMap in my project and but javaetk doesn't support HashMap . So is there any way I can use the functionality of latest JRE in older version of JRE?? Thanks in advance!
