Java- How do i fix these errors

Public static void main (String[] args) Scanner userlnput = new Scanner(System.in); int amount = 0; int $20 = 0; int $10 = 0; int $5 = 0; int $1 = 0; System.out.print(\"Enter the amount: \"); amount = userInput.nextInt(); if (amount > 500) {System.out.println(\"Limit of $500 exceeded!\");} else {System.out.println(\"Bills by denomination: \"); $20 = amount/20; int rest_amount = amount % 20; $10 = rest_amount/10; rest_amount = rest_amount % 10; $5 = rest_amount/5; rest_amount = rest_amount % 5; $1 = rest_amount/1; System.out.printin(\"\\t$20: \" + $20); System.out.printin(\"\\t$10: \" + $10); System.out.printin(\"\\t$5: \" + $5); System.out.printin(\"\\t$l: \" + $1); System.out.println(\"$\" + amount +\"=(\"+ $20 + \" * $20) + (\" + $10 + \" * $10) + (\" + $5 + \" * $5) + (\" + $1 + \" * $1)\");}}}

Solution

//Atm.java

/*

This regex describes something which starts with lowercase and the remainder
is composed of uppercase, lowercase, and numbers
we need to change the name of variables

import java.util.Scanner;

Output:

Enter the amount:
