granite: weight=25.0 value=4 numkind=7
public class inherit
{
abstract class stone
{
protected float weight = 13;
protected int value = 4;
abstract public string tostring( );
}
class aggregate
{
protected int numkind;
}
class granite extends aggregate
{
granite( )
{
weight = 25; numkind = 7;
}
public string tostring( )
{
return "granite: weight="
+ weight + " value="
+ value + " numkind="
+ numkind;
}
}
inherit( )
{
granite g = new granite( );
system. out. println(g);
}
public static void main(string[ ] args)

The instruction ishl (shift left integer) exists in jvm but not in ijvm. it uses the top two values on the stack, replacing the two with a single value, the result. the sec- ond-from-top word of the stack is the operand to be shifted. its content is shifted left by a value between 0 and 31, inclusive, depending on the value of the 5 least signifi- cant bits of the top word on the stack (the other 27 bits of the top word are ignored). zeros are shifted in from the right for as many bits as the shift count. the opcode for ishl is 120 (0x78).a. what is the arithmetic operation equivalent to shifting left with a count of 2? b. extend the microcode to include this instruction as a part of ijv.

Write a full class definition for a class named player , and containing the following members: a data member name of type string .a data member score of type int .a member function called setname that accepts a parameter and assigns it to name . the function returns no value. a member function called setscore that accepts a parameter and assigns it to score . the function returns no value. a member function called getname that accepts no parameters and returns the value of name .a member function called getscore that accepts no parameters and returns the value of score .this is what i have, aparently this is wrong: class player{private: string name; int score; public: void player: : setname (string n){name =n; }void player: : setscore (int s){score = s; }string player: : getname (){return name; }int player: : getscore (){return score; }};
