Hello solo learner's As we know java is very difficult as compared to python. One thing make it hard that is concepts of oops and classes basic language. In this hard pr
Get rid of shared state. Setting aside concurrency and memory visibility,staticmembers will be visible to all instances of the class. Omit thestatickeyword and make these into regular fields publicclassHost{privatefinalString hostName;privatefinalString ip;// Constructor, use this to build new inst...
