Question

 write that in java code    Declare a variable named retVal of type List<PQEntry>   Set retVal equal to a new instance of ArrayList<PQEntry>   Declare a variable named lastAccept of type PQEntry   Set lastAccept equal to null   Declare a variable named mwatts of type int   Set mwatts equal to 0   while mwatts < needAmount && pq is not empty do     Set lastAccept equal to element returned when removing most important item in pq     Increase the value of mwatts by lastAccept.mwattBid     Add lastAccept to the end of retVal   end while   for-each PQEntry ent in retVal     Set ent.payment equal to lastAccept.rate * ent.mwattBid   end for-each   if mwatts > needAmount     Set lastAccept.payment equal to lastAccept.rate * (lastAccept.mwattBid - (mwatts - needAmount))   end if   Return retVal end 

Explanation / Answer

/* Prerequisite: Import java.util.Collection */ import java.util.Collection; /* Code begins here*/ List retVal; retVal=new ArrayList(); PQEntry lastAccept; lastAccept=NULL; int mwatts; mwatts=0; //The type of pq is not mentioned in the question while(mwattsneedAmount) { lastAccept.payment=lastAccept.rate*(lastAccept.mwattBid-(mwatts-needAmount)); } return retVal; /* Code ends here */ /*Declare a variable named retVal of type List*/ List retVal; /*Set retVal equal to a new instance of ArrayList*/ retVal=new ArrayList(); /*Declare a variable named lastAccept of type PQEntry*/ PQEntry lastAccept; /*Set lastAccept equal to null*/ lastAccept=NULL; /*Declare a variable named mwatts of type int*/ int mwatts; /*Set mwatts equal to 0*/ mwatts=0; /*while mwatts needAmount) { /*Set lastAccept.payment equal to lastAccept.rate * (lastAccept.mwattBid - (mwatts - needAmount))*/ lastAccept.payment=lastAccept.rate*(lastAccept.mwattBid-(mwatts-needAmount)); } /*Return retVal*/ return retVal;
