Question

Java programming

Create a simple tip calculator called TipCalcMethod. Your program should read in the bill amount from the command-line, then show 3 tip amounts: 15%, 20% and 25% of the bill. Don't worry about rounding the result to two decimal places, but make sure that the result includes cents (not just dollars). This program will be different than your first Tipcalc program because you will writea method to calculate the tip amount. program will have 2 methods: main) and tip) main( ) will be responsible for 1. converting the command-line value to the appropriate data type 2. calling the tip) method with the bill amount and each of the 3 tip percentages (you will call this method 3 times) 3. printing the results to the screern tip() will be responsible for 1. taking 2 values as input: the bill amount and the tip percentage 2. calculating the tip amount for the given input 3. returning the tip amount calculated name your method tip() as the grading script will be searching for this method to give you credit. Here is an example of what your program output should look like (assuming the command-line i nput was 19.98): 15%: $2.997 28x: $3.996 25%: $4.995

Your vote will motivate me to work better.

The following is the code
//File: TipCalcMethod,java

public class TipCalcMethod {
//Method calculates the tip percentage for the bill amount
public static double tip(double billAmount, double tipPercentage) {
return billAmount * (tipPercentage/100);
}
//Main method to read user input from cmdline and calculate different tip percentages
public static void main(String[] args) {
if(args.length == 0) {
System.err.println("Usage: java TipCalcMethod <bill amount>");
return;
}
double billAmount = Double.parseDouble(args[0]);
//Calculate and display tip percentages
System.out.println("15%: $" + tip(billAmount, 15));
System.out.println("20%: $" + tip(billAmount, 20));
System.out.println("25%: $" + tip(billAmount, 25));
}
}

And finally, this is the output when the code is executed
//Output:

java TipCalcMethod 19.98
