Comparison oin java

Question

i have this code that write a class Compare3 that provides a static method largest. Method largest should take three
Comparable parameters and return the largest of the three (so its return type will also be Comparable)
public class Compare3 {
public static Comparable largest(Comparable x, Comparable y, Comparable z)
if (x.compareTo(y) >= 0 && x.compareTo(z) >= 0)
     return x;
     else if (y.compareTo(x) >= 0 && y.compareTo(z) >= 0)
     return y;
     else
     return z;
and then i want to Write a class Comparisons whose main method tests your largest method above.
(a) First prompt the user for and read in three strings, use your largest method to find the largest of the
three strings, and print it out. (It's easiest to put the call to largest directly in the call to println.) Note
that since largest is a static method, you will call it through its class name, e.g.,
compare3.largest(val1, val2, val3) and
(b) Add code to also prompt the user for three integers and try to use your largest method to find the
largest of the three integers. Does this work? If it does, it?s thanks to autoboxing, which is Java 1.6?s
automatic conversion of ints to Integers.
can someone give me a clue?.
i have something like this but am not sure
ublic class Comparisons
public static void main(String[] args)
               if ( args.length < 3 ){
               System.out.print("This program will find the largest ");
                         System.out.println("of 3 floating-point numbers");
                         System.out.println("entered as command-line arguments.");
               System.out.println("To run this program, type:");
               System.out.println(" java Compare3 num1 num2 num3");
               System.out.print("using numeric values in place of ");
               System.out.println("num1, num2, and num3.");
                         System.exit(x);
                    } // if
               float number1 = Float.parseFloat(args[x]);
               float number2 = Float.parseFloat(args[y]);
               float number3 = Float.parseFloat(args[z]);
               // Find the largest of all three numbers
               // by comparing the third number to the
               // largest of the first two:
               if ( numberz > largest )
               largest = numberz;
               System.out.println("The largest of " + number1
               + ", " + number2
               + ", and " + number3
               + " is " + largest + ".");
it gives me a lot off errors
i DONT KNOW IF I'M DOING THE RIGHT THING,

Answer 1

To start with:
float number1 = Float.parseFloat(args[x]);
float number2 = Float.parseFloat(args[y]);
float number3 = Float.parseFloat(args[z]);What are these mysterious 'x', 'y', and 'z' variables doing here? It looks like you want the first, second, and third command line arguments, but throwing 'x', 'y', and 'z' symbols isn't going to make any magic happen. You need:
float number1 = Float.parseFloat(args[0]);
float number2 = Float.parseFloat(args[1]);
float number3 = Float.parseFloat(args[2]);
Next:
if ( numberz > largest )
largest = numberz;Again, where did this 'numberz' come from? Also, where did 'largest' come from?
You're just throwing code at a wall hoping some of it will stick and hoping for magic to happen.
i DONT KNOW IF I'M DOING THE RIGHT THINGClearly you're not. It isn't magic. It requires actual logical thinking.
