Please edit my following JAVA code so that there is no main function. Please show how to write the class so that only functions are called in a separate main.java file. The functionality of the current code should still hold. Thanks in advance.

import java.math.RoundingMode; import java.text.DecimalFormat; import java.util.Scanner; public class enterfingoals { private static DecimalFormat df = new DecimalFormat("0.00"); public static float readFloat(Scanner reader) { float num; while (true) { try { num = Float.parseFloat(reader.nextLine()); return num; } catch (Exception e) { System.out.println("Please enter a numerical value."); } } } public static void main(String args[]) { float saveAmt; float spendAmt; Scanner in = new Scanner(System.in); System.out.println("How much would you like to spend per week?"); spendAmt = readFloat(in); while (spendAmt < 0) { System.out.println("Please enter a value of 0 or higher."); spendAmt = readFloat(in); } System.out.println("Spending amount of $" + df.format(spendAmt) + " has been saved to your user profile!"); System.out.println(" "); System.out.println("How much would you like to save per week?"); saveAmt = readFloat(in); while (saveAmt < 0) { System.out.println("Please enter a value of 0 or higher."); saveAmt = readFloat(in); } System.out.println("Saving amount of $" + df.format(saveAmt) + " has been saved to your user profile!"); } }
