Thread: Alternative method solutions

Still practicing java questions for improvement
I completed 2 solutions to a question, please tell me which one is more accurate:

This is what the question is based on:
land line to land line :20 cents
land line to LOWCALL mobile: 50 cents
land line to other mobile network: 1.20

Packages:
0 -NONE
1: GOLD >>>100.00 1 MONTH, 500 free land line mins and 50 free LOWCALL mobile mins
2: PLATINUM>>>150.00 1 MONTH, UNLIMITED free land line mins and 100 free LOWCALL mobile mins


So with the given parameters I had to calculate the number of landLine mins using a mthod:
Here is my 1st solution:

public static double calcLandMinutes (int numLandLineMins, int packageNum){
	double landLineCost=0;
 
	if(packageNum==0)
	{
		landLineCost = numlandLineMins * 0.20;
	}
	else if(packageNum==1)
	{
		landLineCost = 100;
	}
	else if(packageNum==2)
	{
		landLineCost= 150;
	}
}

Here is my 2nd solution:

public static double calcLandMinutes (int numLandLineMins, int packageNum){
	double landLineCost=0;
 
	if(packageNum==0)
	{
		landLineCost = numlandLineMins * 0.20;
	}
	else if(packageNum==1)
	{
		if (numLandLineMins > 500) 
		{
			landLineCost = (numlandLineMins - 500 )* 0.20;
		}
		else 
		{
			landLineCost = 100;
		}
	}
	else if(packageNum==2)
	{
		landLineCost= 150;
	}
}

Am not sure that's why I posted
