help in java coding

[aal300m]

I am trying to define a java class named NumberCruncher that has a single int variable as its only instance variable. Then I have to define methods that perform the following operations on its number: get, double, triple, square, and cube. Sent the intial value of the number with a constructer.

Can anyone help me with this. It will be deeply appreciate it.

I'm assuming this is homework for a beginner course in java. Since this task is rather simple I'll also assume that the problem lies in the fact that you don't know how to construct a class. So I'll give you a skeleton for this problem and allow you to fill in the missing code.

NumberCruncher.java

public class NumberCruncher{

private int number;

public NumberCruncher(int num)
{
//set number equal to num
}

public int getNumber()
{
//return the original number
}

public int doubleNumber()
{
//calculate and return double the original number
}

public int tripleNumber()
{
//calculate and return triple the original number
}

public int squareNumber()
{
//calculate and return the square of the number
}

public int cubeNumber()
{
//calculate and return the cuber of the number
}

}


testNumberCruncher.java

public class testNumberCruncher{

public static void main (String[] args){

NumberCruncher test = new NumberCruncher(2);
System.out.println("The number in the cruncher is " + test.getNumber());
System.out.println("Double the number is " + test.doubleNumber());
System.out.println("Triple the number is " + test.tripleNumber());
System.out.println("Square of the number is " + test.squareNumber());
System.out.println("Cube of the number is " + test.cubeNumber());
}

}
