Please edit my following JAVA code so that if the user enters a letter or any symbol (anything non-numeric) that an error message will be given: "Please enter a value greater than 0." Thanks in advance.

import java.math.RoundingMode; import java.text.DecimalFormat; import java.util.Scanner; public class EnterFinancialGoals { private static DecimalFormat df = new DecimalFormat("0.00"); 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=in.nextFloat(); while (spendAmt<0) { System.out.println("Please enter a value of 0 or higher."); spendAmt = in.nextFloat(); } 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=in.nextFloat(); while (saveAmt<0) { System.out.println("Please enter a value of 0 or higher."); saveAmt = in.nextFloat(); } System.out.println("Saving amount of $" + df.format(saveAmt) + " has been saved to your user profile!"); } }
