Question

Write the definition of a class Counter containing: An instance variable named counter of type int. An instance variable named limit of type int. A static int variable named nCounters which is initialized to 0. A constructor taking two int parameters that assigns the first one to counter and the second one to limit. It also adds one to the static variable nCounters. A method named increment. It does not take parameters or return a value; if the instance variable counter is less than limit, increment just adds one to the instance variable counter. A method named decrement that also doesn't take parameters or return a value; if counter is greater than zero, it just subtracts one from the counter. A method named getValue that returns the value of the instance variable counter. A static method named getNCounters that returns the value of the static variable nCounters.

Answer 1

Answer:

see explaination

Explanation:

public class Counter

{ int counter,limit;

static int nCounters = 0;

Counter(int a,int b)

{ counter=a; limit=b;

nCounters++;

}

void increment()

{ if(counter<limit)

counter++;

}

void decrement()

{ if(counter>0)

counter--;

}

private int getValue()

{ return counter;

}

private static int getNCounters()

{ return nCounters;

}

}
